mkfontscale - create an index of scalable font files for X
mkfontscale [ -b ] [ -s ] [ -o filename ] [
  -x suffix ] [ -a encoding ] ... [ -f
  fuzz ] [ -l ] [ -e directory ] [ -p
  prefix ] [ -r prefix ] [ -n prefix ] [
  -u | -U ] [ -v ] [ -- ] [ directory ] ...
For each directory argument, mkfontscale reads all of the scalable font
  files in the directory. For every font file found, an X11 font name (XLFD) is
  generated, and is written together with the file name to a file
  fonts.scale in the directory.
The resulting fonts.scale file should be checked and
    possibly manually edited before being used as input for the
    mkfontdir(1) program.
  - -b
- read bitmap fonts. By default, bitmap fonts are ignored.
- -s
- ignore scalable fonts. By default, scalable fonts are read. If -b
      is set, this flag has the side effect of enabling the reading of
      fonts.scale files.
- -o filename
- send program output to filename; default is fonts.scale if
      bitmap fonts are not being read, and fonts.dir if they are. If
      filename is relative, it is created in the directory being
      processed. If it is the special value -, output is written to
      standard output.
- -x suffix
- exclude all files with the specified suffix.
- -a encoding
- add encoding to the list of encodings searched for.
- -f fuzz
- set the fraction of characters that may be missing in large encodings to
      fuzz percent. Defaults to 2%.
- -l
- Write fonts.dir files suitable for implementations that cannot
      re-encode legacy fonts (BDF and PCF). By default, it is assumed that the
      implementation can re-encode Unicode-encoded legacy fonts.
- -e
- specifies a directory with encoding files. Every such directory is scanned
      for encoding files, the list of which is then written to an
      "encodings.dir" file in every font directory.
- -p
- Specifies a prefix that is prepended to the encoding file path names when
      they are written to the "encodings.dir" file. The prefix is
      prepended literally: if a `/' is required between the prefix and the path
      names, it must be supplied explicitly as part of the prefix.
- -r
- Keep non-absolute encoding directories in their relative form when writing
      the "encodings.dir" file. The default is to convert relative
      encoding directories to absolute directories by prepending the current
      directory. The positioning of this options is significant, as this option
      only applies to subsequent -e options.
- -n
- do not scan for fonts, do not write font directory files. This option is
      useful when generating encoding directories only.
- -u, -U
- disable (-u) or enable (-U) indexing of ISO 10646:1 font
      encodings (default: enabled).
- -v
- print program version and exit.
- --
- end of options.
X(7), Xserver(1), mkfontdir(1), ttmkfdir(1), xfs(1), xset(1)
The format of the fonts.scale, fonts.dir and encodings.dir
  files is documented in the mkfontdir(1) manual page.Mkfontscale will overwrite any fonts.scale file even
    if it has been hand-edited.
mkfontscale -b -s -l is equivalent to mkfontdir.
The version of mkfontscale included in this X.Org Foundation release was
  originally written by Juliusz Chroboczek <jch@freedesktop.org> for the
  XFree86 project. The functionality of this program was inspired by the
  ttmkfdir utility by Joerg Pommnitz.
