NAME

       gtk4-update-icon-cache - Icon theme caching utility

SYNOPSIS

       gtk4-update-icon-cache [OPTIONS...] <PATH>

DESCRIPTION

       gtk4-update-icon-cache creates mmap(2)-able cache files for icon themes.

       It expects to be given the PATH to an icon theme directory containing an index.theme, e.g.
       /usr/share/icons/hicolor, and writes  a  icon-theme.cache  containing  cached  information
       about the icons in the directory tree below the given directory.

       GTK  can  use  the  cache files created by gtk4-update-icon-cache to avoid a lot of system
       call and disk seek overhead when the application starts. Since the  format  of  the  cache
       files  allows  them  to  be shared across multiple processes, for instance using the POSIX
       mmap(2) system call, the overall memory consumption is reduced as well.

OPTIONS

       -f, --force
          Overwrite an existing cache file even if it appears to be up-to-date.

       -t, --ignore-theme-index
          Don't check for the existence of index.theme in the icon theme directory.  Without this
          option,  gtk4-update-icon-cache  refuses  to  create an icon cache in a directory which
          does not appear to be the toplevel directory of an icon theme.

       -i, --index-only
          Don't include image data in the cache.

       --include-image-data
          Include image data in the cache.

       -c, --source <NAME>
          Output a C header file declaring a constant NAME with the contents of the icon cache.

       -q, --quiet
          Turn off verbose output.

       -v, --validate
          Validate existing icon cache.

                                                                         GTK4-UPDATE-ICON-CACHE()
