update-fonts-alias assembles a fonts.alias file in an X font directory using one or more alias files found in a subdirectory of /etc/X11/fonts/. It is typically invoked only from the post-installation and post-removal scripts of a package containing X Window System fonts that provide aliases for their XLFD names, but may be invoked at any time to reconstruct fonts.alias files. For each directory, which is simply the last component of its path (such as '75dpi' or 'misc'), update-fonts-alias will assemble either /usr/lib/X11/fonts/directory/fonts.alias or /usr/share/fonts/X11/directory/fonts.alias from the files found in /etc/X11/fonts/directory/package.alias.
This enables multiple packages to provide aliases for fonts in the same directory. No font package actually provides the fonts.alias file in the X font directory itself, so there is no danger of overwriting one package's aliases with those of another.
For instance, the two packages 'xfonts-base' and 'xfonts-base-transcoded' may both install fonts into the directory /usr/lib/X11/fonts/misc. They each place their fonts.alias files in /etc/X11/fonts/misc/xfonts-base.alias and /etc/X11/fonts/misc/xfonts-base-transcoded.alias (respectively). update-fonts-alias concatenates these two files (as well as any others that match /etc/X11/fonts/misc/*.alias) into /usr/lib/X11/fonts/misc/fonts.alias.
The format of fonts.alias files is described in the (1x) manual page.
update-fonts-alias takes one or more X font directory names to operate on as operands. Only the final path component of the directory name should be specified; e.g.,
