NAME

       lensfun-update-data - update Lensfun's database

SYNOPSIS

       lensfun-update-data

DESCRIPTION

       Lensfun is a library that corrects flaws in photographic images introduced by the lens.  It also contains
       a  comprehensive  database  of cameras and lenses together with their characteristics to be able to apply
       automatic corrections of images taken with  these  devices.   Lensfun  is  used  by  darktable,  digiKam,
       rawstudio, GimpLensfun, UFRaw, and others.

       lensfun-update-data  is  a  command-line program that updates Lensfun's database.  It looks whether a new
       version is available online, and if this is the case, it fetches  the  latest  version  and  installs  it
       locally.   If  called  as  root, the database is installed system-wide, otherwise, it is installed in the
       user's directory.

FILES

       lensfun-update-data will place the fetched database in /var/lib/lensfun-updates/ (if called as  root)  or
       in  ~/.local/share/lensfun/updates/  (otherwise).  If necessary, it will create this directory.  If there
       is already a database, it is replaced fully.  If Lensfun detects a database in one of these  directories,
       it will use that instead of the default location below /usr/....

DIAGNOSTICS

       lensfun-update-data prints log messages to stdout.

       Exit status:
                                     ┌───┬──────────────────────────────────────┐
