NAME
install-tl - TeX Live cross-platform installer
SYNOPSIS
install-tl [option]...
install-tl-windows.bat [option]...
DESCRIPTION
This installer creates a runnable TeX Live installation from various media, including over the network,
from local hard disk, a DVD, etc. The installer works on all platforms supported by TeX Live. For
information on initially downloading TeX Live, see <https://tug.org/texlive/acquire.html>.
The basic idea of TeX Live installation is for you to choose one of the top-level schemes, each of which
is defined as a different set of collections and packages, where a collection is a set of packages, and a
package is what contains actual files. Each package is in exactly one collection, while schemes can
contain any combination of packages and collections.
Within the installer, you can choose a scheme, and further customize the set of collections to install,
but not the set of the packages. To work at the package level, use "tlmgr" (reference just below) after
the initial installation is complete.
The default is "scheme-full", which installs everything, and this is highly recommended.
REFERENCES
Post-installation configuration, package updates, and more, are handled through tlmgr(1), the TeX Live
Manager (<https://tug.org/texlive/tlmgr.html>).
The most up-to-date version of this installer documentation is on the Internet at

EXAMPLES
With no options, "install-tl" drops you into an interactive menu where essentially all default settings
can be changed. With options, you can initialize the settings in various ways, or perform the
installation without interaction. Some examples:
"install-tl --paper=letter"
Initialize paper size setting. The only values allowed are "letter" and (the default) "a4".
"install-tl --scheme" scheme
Initialize the installation scheme; the default is "full". For a list of schemes, see the
interactive "S" menu.
"install-tl --no-interaction"
Perform the installation immediately after parsing options, without entering the interactive menu.
"install-tl --profile" texlive.profile
Install, without interaction, according to the given TL profile file; see "PROFILES" below. To
initialize from the profile and then enter the interactive menu, add "--init-from-profile".
Full documentation follows.
OPTIONS
As usual, all options can be specified in any order, and with either a leading "-" or "--". An argument
value can be separated from its option by either a space or "=".
The options relating to customization of the installation can also be selected in the interactive
installation menus (GUI or text).
-gui [[=]module]
-no-gui
If no module is given, starts the Tcl/Tk (see below) GUI installer.
If module is given loads the given installer module. Currently the following modules are supported:
"text"
The text mode user interface (default on Unix systems, including Macs). Same as the "-no-gui"
option.
"tcl" (or "perltk" or "wizard" or "expert" or nothing)
The Tcl/Tk user interface (default on Windows). It starts with a small number of configuration
options, roughly equivalent to what the former wizard option offers, but a button "Advanced"
takes you to a screen with roughly the same options as the former "perltk" interface.
The default GUI requires Tcl/Tk. This was standard on Macs, but has been removed in the latest macOS
releases. It's often already installed on GNU/Linux, or can be easily installed through a distro
package manager. For Windows, TeX Live provides a Tcl/Tk runtime.
-lang llcode
By default, the Tcl GUI uses the language detection built into Tcl/Tk. If that fails you can select a
different language by giving this option with a language code (based on ISO 639-1). Currently
supported (but not necessarily completely translated) are: English (en, default), Czech (cs), German
(de), French (fr), Italian (it), Japanese (ja), Dutch (nl), Polish (pl), Brazilian Portuguese
(pt_BR), Russian (ru), Slovak (sk), Slovenian (sl), Serbian (sr), Ukrainian (uk), Vietnamese (vi),
simplified Chinese (zh_CN), and traditional Chinese (zh_TW).
-repository url|path
Specify the package repository to be used as the source of the installation. In short, this can be a
directory name or a url using http(s), ftp, or scp. The documentation for "tlmgr" has the details
(<https://tug.org/texlive/doc/tlmgr.html#OPTIONS>).
For installation, the default is to pick a mirror automatically, using
<https://mirror.ctan.org/systems/texlive/tlnet>; the chosen mirror is then used for the entire
download. You can use the special argument "ctan" as an abbreviation for this. (See
<https://ctan.org> for more about CTAN and its mirrors.)
After installation is complete, you can use that installation as the repository for another
installation. If you chose to install less than the full scheme containing all packages, the list of
available schemes will be adjusted accordingly.
-select-repository
This option allows you to choose a particular mirror from the current list of active CTAN mirrors.
This option is supported in the "text" and "gui" installer modes, and will also offer to install from
local media if available, or from a repository specified on the command line. It's useful when the
(default) automatic redirection does not choose a good host for you.
-all-options
Normally options not relevant to the current platform are not shown (e.g., when running on Unix,
Windows-specific options are omitted). Giving this command line option allows configuring such
"foreign" settings.
-custom-bin path
If you have built your own set of TeX Live binaries (e.g., because precompiled binaries were not
provided by TL for your platform), this option allows you to specify the path to a directory where
the binaries for the current system are present. The installation will continue as usual, but at the
end all files from path are copied over to "bin/custom/" under your installation directory and this
"bin/custom/" directory is what will be added to the path for the post-install actions. To install
multiple custom binary sets, manually rename "custom" before doing each.
For more information on custom binaries, see <https://tug.org/texlive/custom-bin.html>. For general
information on building TeX Live, see <https://tug.org/texlive/build.html>.
-debug-fakenet
Pretend we're doing a network install. This is for the sole purpose of testing the code to handle
broken downloads, via moving package files aside in a tlnet mirror hierarchy.
-debug-setup-vars
Print final values of directory variables; for more debugging information on how they were set, also
specify "-v".
-debug-translation
In the former Perl/Tk GUI modes, this option reported any missing, or more likely untranslated,
messages to standard error. Not yet implemented for the Tcl interface. Helpful for translators to see
what remains to be done.
-force-platform platform
Instead of auto-detecting the current platform, use platform. Binaries for this platform must be
present in "bin/"platform"/" and they must be runnable, or installation will fail. "-force-arch" is a
synonym.
-help, --help, -?
Display this help and exit. (This help is also on the web at
<https://tug.org/texlive/doc/install-tl.html>). Sometimes the "perldoc" and/or "PAGER" programs on
the system have problems, possibly resulting in control characters being literally output. This can't
always be detected, but you can set the "NOPERLDOC" environment variable and "perldoc" will not be
used.
-in-place
This is a quick-and-dirty installation option in case you already have an rsync or svn checkout of
TeX Live. It will use the checkout as-is and will just do the necessary post-install. Be warned
that the file "tlpkg/texlive.tlpdb" may be rewritten, that removal has to be done manually, and that
the only realistic way to maintain this installation is to redo it from time to time. This option is
not available via the installer interfaces. USE AT YOUR OWN RISK.
-init-from-profile profile_file
Similar to -profile (see "PROFILES" below), but only initializes the installation configuration from
profile_file and then starts a normal interactive session. Environment variables are not ignored.
-logfile file
Write both all messages (informational, debugging, warnings) to file, in addition to standard output
or standard error.
If this option is not given, the installer will create a log file in the root of the writable
installation tree, for example, "/usr/local/texlive/YYYY/install-tl.log" for the YYYY release.
-no-cls
For the text mode installer only: do not clear the screen when entering a new menu. For debugging.
-no-continue
Quit early on installation failure of a non-core package.
By default, a few core packages are installed first; then, a failed installation of any other (non-
core) package is noted, but does not stop the installation. Any such failed packages are retried,
once.
If the retry also fails, by default the installer proceeds to completion anyway, with the idea that
it was a transient network problem and reinstallation will succeed later. If this option is
specified, and the retry fails, the installer aborts.
-no-doc-install
-no-src-install
Do not install the documentation resp. source package files, both for the immediate installation and
for future updates. After installation, inclusion of the doc/src files can be re-enabled via "tlmgr":
tlmgr option docfiles 1
tlmgr option srcfiles 1
If you later find that you want the doc/src files for a package that has been installed without them,
you can get them like this (using the "fontspec" package as the example):
tlmgr install --reinstall --with-doc --with-src fontspec
The source files mentioned here are those relating to TeX packages, such as ".dtx" files. The sources
that are compiled to make the binaries are available separately: see <https://tug.org/texlive/svn/>.
-no-installation
Do not perform any installation. This is for debugging the initialization and setup routines without
touching the disk.
-no-interaction
Do not enter the interactive menu; immediately perform the installation after initialization and
option parsing. Also omit the check for a previous installation and asking about importing previous
settings.
-no-persistent-downloads
-persistent-downloads
For network installs, activating this option makes the installer try to set up a persistent
connection using the "LWP" Perl module. This opens only one connection between your computer and the
server per session and reuses it, instead of initiating a new download for each package, which
typically yields a significant speed-up.
This option is turned on by default, and the installation program will fall back to using "wget" if
this is not possible. To disable usage of LWP and persistent connections, use
"-no-persistent-downloads".
-no-verify-downloads
By default, if a GnuPG "gpg" binary is found in PATH, downloads are verified against a cryptographic
signature. This option disables such verification. The full description is in the Crytographic
Verification section of the "tlmgr" documentation, e.g.,
<https://tug.org/texlive/doc/tlmgr.html#CRYPTOGRAPHIC-VERIFICATION>
-non-admin
For Windows only: configure for the current user, not for all users.
-paper "a4"|"letter"
Set the default paper size for all TeX Live programs, as specified. The default is "a4". The paper
size can be set after installation with the "tlmgr paper" command.
-portable
Install for portable use, e.g., on a USB stick. See the "instopt_portable" description below for
details.
-print-platform
Print the TeX Live identifier for the detected platform (hardware/operating system) combination to
standard output, and exit. "-print-arch" is a synonym.
-profile profile_file
Load profile_file and do the installation with no user interaction, that is, a batch (unattended)
install. Environment variables are ignored. See "PROFILES" below.
-q Omit normal informational messages.
-scheme scheme
Schemes are the highest level of package grouping in TeX Live; the default is to use the "full"
scheme, which includes everything. This option overrides that default. The scheme argument value may
optionally have a prefix "scheme-". The list of supported scheme names depends on what your package
repository provides; see the interactive menu list.
-texdir dir
Specify the system installation directory; the default is "/usr/local/texlive/YYYY" for release YYYY.
Specifying this option also causes the "TEXMFLOCAL", "TEXMFSYSCONFIG", and "TEXMFSYSVAR" directories
to be set as subdirectories of dir, so they don't have to be set individually.
There is a brief summary of these directories trees at "DIRECTORY TREES" below; for details on the
trees set up by default, and their intended usage, see the main TeX Live documentation at
<https://tug.org/texlive/doc>.
-texuserdir dir
Specify the user installation directory; the default is "~/.texliveYYYY" (except on Macs, where there
is no leading dot). Specifying this also causes the "TEXMFHOME", "TEXMFCONFIG", and "TEXMFVAR"
directories to be set as subdirectories of dir.
-texmflocal dir
Specify the "TEXMFLOCAL" directory; the default is "/usr/local/texlive/texmf-local", that is, one
level up from the main installation. This is so locally-installed packages can be easily used across
releases, which is usually desirable. Specifying the "-texdir" option changes this, putting
"TEXMFLOCAL" under the main tree. The "-texmflocal" option can be used to specify an explicit
directory.
Anything installed here must follow the TeX directory structure (TDS), e.g.,
"TEXMFHOME/tex/latex/mypkg/mypkg.sty". TDS reference: <https://tug.org/tds>.
-texmfhome dir
Specify the "TEXMFHOME" directory; the default is "~/texmf", except on Macs, where it is
"~/Library/texmf". Analogously to "TEXMFLOCAL", the "-texuserdir" option changes this default.
Also as with "TEXMFLOCAL", anything installed here must follow the TDS.
-texmfsysconfig dir
-texmfsysvar dir
Specify the "TEXMFSYSCONFIG" and "TEXMFSYSVAR" system directories.
-texmfconfig dir
-texmfvar dir
Specify the "TEXMFCONFIG" and "TEXMFVAR" user directories. The defaults are
"~/.texliveYYYY/texmf-{config,var}", except on Macs, where the leading dot is omitted
("~/texliveYYYY/...").
-v Include verbose debugging messages; repeat for maximum debugging: "-v -v". (Further repeats are
accepted but ignored.)
-version, --version
Output version information and exit. If "-v" is also given, the versions of the TeX Live modules
used are also reported.
PROFILES
A profile file normally contains all the values needed to perform an installation. After a normal
installation has finished, a profile for that exact installation is written to the file
"tlpkg/texlive.profile". In addition, from the text menu one can select "P" to save the current setup as
a profile at any time. These are small text files; feel free to peruse and edit them according to your
needs.
Such a profile file can be given as the argument to "-profile", for example to redo the exact same
installation on a different system. Alternatively, you can use a custom profile, most easily created by
starting from a generated one and changing values. An empty profile file will cause the installer to use
the defaults.
As mentioned above, the installer only supports selection by scheme and collections, not individual
packages, so packages cannot be specified in profile files either. Use "tlmgr" to work at the package
level.
Within a profile file, each line consists of
variable [value]
except for comment lines starting with "#". The possible variable names are listed below. Values, when
present, are either 0 or 1 for booleans, or strings (which must be specified without any quote
characters). Leading whitespace is ignored.
If the variable "selected_scheme" is defined and no collection variables at all are defined, then the
collections required by the specified scheme (which might change over time) are installed, without
explicitly listing them. This eases maintenance of profile files. If any collections are specified in a
profile, though, then the scheme is ignored and all desired collections must be given explicitly.
For example, a line
selected_scheme scheme-small
along with definitions for the installation directories (given below under "path options") suffices to
install the "small" scheme with all default options. The schemes are described in the "S" menu in the
text installer, or equivalent.
In addition to "selected_scheme", here are the other variable names supported in a profile:
collection options (prefix "collection-")
Collections are specified with a variable name with the prefix "collection-" followed by a collection
name; there is no value. For instance, "collection-basic". The collections are described in the "C"
menu.
Schemes and collections (and packages) are ultimately defined by the files in the "tlpkg/tlpsrc/" source
directory.
path options
It is best to define all of these, even though they may not be used in a given installation, so as to
avoid unintentionally getting a default value that could cause problems later.
TEXDIR
TEXMFLOCAL
TEXMFSYSCONFIG
TEXMFSYSVAR
TEXMFCONFIG
TEXMFVAR
TEXMFHOME
installer options (prefix "instopt_")
"instopt_adjustpath" (default 0 on Unix, 1 on Windows)
Adjust "PATH" environment variable.
"instopt_adjustrepo" (default 1)
Set remote repository to a multiplexed CTAN mirror after installation; see "-repository" above.
"instopt_letter" (default 0)
Set letter size paper as the default, instead of a4.
"instopt_portable" (default 0)
Install for portable use, e.g., on a USB stick, without touching the host system. Specifically, this
forces the user directories "TEXMFHOME", "TEXMFCONFIG", "TEXMFVAR" to be identical to the system
directories "TEXMFLOCAL", "TEXMFSYSCONFIG", "TEXMFSYSVAR", respectively (regardless of other options
and environment variable.)
In addition, on Windows, it disables the desktop integration, path adjustment, and file associations
actions usually performed.
"instopt_write18_restricted" (default 1)
Enable "\write18" for a restricted set of programs.
tlpdb options (prefix "tlpdbopt_")
The definitive list is given in "tlpkg/TeXLive/TLConfig.pm", in the hash
%TeXLive::TLConfig::TLPDBOptions, together with explanations. All items given there except for
"tlpdbopt_location" can be specified. Here is the current list:
tlpdbopt_autobackup
tlpdbopt_backupdir
tlpdbopt_create_formats
tlpdbopt_desktop_integration
tlpdbopt_file_assocs
tlpdbopt_generate_updmap
tlpdbopt_install_docfiles
tlpdbopt_install_srcfiles
tlpdbopt_post_code
tlpdbopt_sys_bin
tlpdbopt_sys_info
tlpdbopt_sys_man
tlpdbopt_w32_multi_user
platform options (prefix "binary_")
For each supported platform in TeX Live (directories under "bin/"), the variable "binary_"PLATFORM can be
set with value 1. For example:
binary_x86_64-linux 1
If no "binary_" settings are made, the default is whatever the current machine is running.
In releases before 2017, many profile variables had different names (not documented here; see the
"install-tl" source). They are accepted and transformed to the names given above. When a profile is
written, the names above are always used.
For more details on all of the above options, consult the TeX Live installation manual, linked from
<https://tug.org/texlive/doc>.
ENVIRONMENT VARIABLES
For ease in scripting and debugging, "install-tl" looks for the following environment variables. They are
not of interest for normal user installations.
"NOPERLDOC"
Don't try to run the "--help" message through "perldoc".
"TEXLIVE_DOWNLOADER"
"TL_DOWNLOAD_PROGRAM"
"TL_DOWNLOAD_ARGS"
These override the normal choice of a download program; see the "tlmgr" documentation, e.g.,
<https://tug.org/texlive/doc/tlmgr.html#ENVIRONMENT-VARIABLES>.
"TEXLIVE_INSTALL_ENV_NOCHECK"
Omit the check for environment variables containing the string "tex". People developing TeX-related
software are likely to have many such variables.
"TEXLIVE_INSTALL_NO_CONTEXT_CACHE"
Omit creating the ConTeXt cache. This is useful for redistributors.
"TEXLIVE_INSTALL_NO_DISKCHECK"
If set to 1, omit free disk space check. By default, if a POSIX-compliant "df" program (supporting
"-Pk") is available, the installer checks for available disk space in the selected installation
location, and will abort installation if there is insufficient disk space, plus a margin of 100MB. An
equivalent check is made on Windows (not involving "df").
"TEXLIVE_INSTALL_NO_RESUME"
Omit check for installing on top of a previous installation and then asking about importing previous
settings.
"TEXLIVE_INSTALL_NO_WELCOME"
Omit printing the welcome message after successful installation, e.g., when testing.
"TEXLIVE_INSTALL_PAPER"
Set the default paper size for all relevant programs; must be either "letter" or "a4". The default is
"a4".
"TEXLIVE_INSTALL_PREFIX"
"TEXLIVE_INSTALL_TEXMFCONFIG"
"TEXLIVE_INSTALL_TEXMFVAR"
"TEXLIVE_INSTALL_TEXMFHOME"
"TEXLIVE_INSTALL_TEXMFLOCAL"
"TEXLIVE_INSTALL_TEXMFSYSCONFIG"
"TEXLIVE_INSTALL_TEXMFSYSVAR"
Specify the respective directories. "TEXLIVE_INSTALL_PREFIX" defaults to "/usr/local/texlive". All
the defaults can be seen by running the installer interactively and then typing "D" for the directory
menu.
The various command line options for specifying directories override these environment variables;
since specifying both is usually accidental, a warning is given if the values are different.
DIRECTORY TREES
There are a plethora of ways to specify the plethora of directory trees used by TeX Live. By far the
simplest, and recommended, approach is not to change anything. The defaults suffice for the vast majority
of installations.
But, for the sake of explanation, here is a table of the trees and the command line options that change
them. The first group of three are system directories, and the second group of three are user
directories; the two groups are quite analogous.
+----------------+--------------------------------------+--------------+------------------+
| tree | default | group change | single change |
+----------------+--------------------------------------+--------------+------------------+
| TEXMFLOCAL | /usr/local/texlive/texmf-local | --texdir | --texmflocal |
| TEXMFSYSVAR | /usr/local/texlive/YYYY/texmf-var | --texdir | --texmfsysvar |
| TEXMFSYSCONFIG | /usr/local/texlive/YYYY/texmf-config | --texdir | --texmfsysconfig |
+----------------+--------------------------------------+--------------+------------------+
| TEXMFHOME | ~/texmf | --texuserdir | --texmfhome |
| TEXMFVAR | ~/.texliveYYYY/texmf-var | --texuserdir | --texmfvar |
| TEXMFCONFIG | ~/.texliveYYYY/texmf-config | --texuserdir | --texmfconfig |
+----------------+--------------------------------------+--------------+------------------+
In addition, as mentioned in the previous section, each tree has an environment variable
"TEXLIVE_INSTALL_"tree which overrides the default; command line and profile settings both override
environment variable settings.
The defaults vary slightly on Macs, as explained above in "OPTIONS".
For the user trees, the default value uses "~", and this is left as a literal "~" in "texmf.cnf". That
way, each user can have their own "TEXMFHOME", etc., as intended. On the other hand, for the system
trees, if "~" is used during the installation, this is assumed to simply be a typing shorthand, and the
expanded home directory is written in "texmf.cnf", since it doesn't make sense to have user-specific
system directories.
For more on the directory trees and their intended usage, see the main TeX Live documentation at
<https://tug.org/texlive/doc>.
BUGS
The "install-tl" script copies itself into the installed tree. Usually, it can be run from there, using
the installed tree as the source for another installation. Occasionally, however, there may be
incompatibilities in the code of the new "install-tl" and the infrastructure, resulting in (probably)
inscrutable Perl errors. The way forward is to run "install-tl" out of the installer package
("install-tl-unx.tar.gz" or "install-tl.zip") instead of the installation. Feel free to also report the
issue; usually the code can be easily synced up again.
By the way, do not try to use "install-tl" to adjust options or installed packages in an existing
installed tree. Use "tlmgr" instead.
