NAME

       dirconv — locate and transcode mixed-encoding file names

SYNOPSIS

       dirconv [-078dFhnpruvw] [-f charset] [-x regex] [path ...]

DESCRIPTION

       The  dirconv  utility  recursively  scans  the  specified  path(s)  and  classifies files and directories
       according to whether their names are pure 7-bit ASCII, non-ASCII but valid UTF-8,  double-UTF-8  (WTF-8),
       or neither.

       Names in the latter category are assumed to be Latin-1, unless a different encoding is specified with the
       -f option.

       By default, the dirconv utility then prints the names that are neither pure 7-bit ASCII nor valid UTF-8.

       The following options are available:

       -0      Print a NUL character rather than a newline after each path.  This option has no effect if the -n
               option was also specified.

       -7      Select names that are pure 7-bit ASCII.

       -8      Select  names  that  contain  non-ASCII  characters but are not valid UTF-8.  This is the default
               unless the -7, -u and / or -w options are specified.

       -d      Show debugging information.  This option can be specified multiple times to increase the level of
               detail.

       -F      In conjunction with the -r option, force renaming a file when the target already exists.

       -f charset
               Specify the assumed character set for non-ASCII, non-UTF-8 names.  The default is “iso8859-1”.

       -h      Print a usage message and exit.

       -n      In conjunction with the -r option, show what would have happened, but do not actually rename  any
               files.

       -p      Print the selected names.

       -r      Attempt to convert the selected names to UTF-8 and rename the files and directories.

       -u      Select names which contain non-ASCII characters and are valid UTF-8 but not WTF-8.

       -v      Print the source reversion number and exit.

       -w      Select names which seem to be WTF-8-encoded.

       -x regex
               Do  not  inspect files and directories whose unconverted names match the specified POSIX extended
               regular expression.

AUTHORS

       The dirconv utility and this manual page  were  written  by  Dag-Erling  Smørgrav  <des@des.no>  for  the
       University of Oslo.

NOTES

       The dirconv utility works by attempting to decode each name as if it were a sequence of UTF-8 characters.
       It is possible, but highly unlikely, that a random string of characters in a non-UTF single-byte encoding
       would look like a valid UTF-8 sequence.

       Reliable detection of WTF-8 is only possible if the original 8-bit encoding is known.

       The  exclusion  filter  is  applied  before  name  conversion.  Character classes are unlikely to work as
       expected on unconverted names.
