Disk information (including directory contents) that has recently been access is stored in the disk cache in memory by the kernel should it be needed again. Until something overwrites this cache (eg. a newer read on a large file) or the related data on the disk gets changed (the cache pages becomes "dirty") any reads on that data are done in memory.

GTK-UPDATE-ICON-C(1)						  [FIXME: manual]					      GTK-UPDATE-ICON-C(1)

NAME
gtk-update-icon-cache - Icon theme caching utility SYNOPSIS
gtk-update-icon-cache [--force] [--ignore-theme-index] [--index-only] [--source [name]] [--quiet] [--validate] {iconpath} DESCRIPTION
gtk-update-icon-cache creates mmap()able cache files for icon themes. It expects to be given the path to a 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 gtk-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 mmap()ed shared between multiple applications, the overall memory consumption is reduced as well. OPTIONS
--force, -f Overwrite an existing cache file even if it appears to be uptodate. --ignore-theme-index, -t Don't check for the existence of 'index.theme' in the icon theme directory. Without this option, gtk-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. --index-only, -i Don't include image data in the cache. --source, -c Output a C header file declaring a constant name with the contents of the icon cache. --quiet, -q Turn off verbose output. --validate, -v Validate existing icon cache. BUGS
None known yet. [FIXME: source] 10/11/2013 GTK-UPDATE-ICON-C(1)
