I find myself doing this sort of thing a fair bit and setting up a local param_val() function makes the code much more maintainable/extendable/readable,
and as long as your only processing a few files the overhead can pretty much be ignored, more often than not the file will still be in the cache anyway.


Remember your going to be comming along in a year or two and going "What the $%#$ is this damn awk script doing!"
Code:
#!/bin/bash
 
function param_val {
    sed -n "s/^${1}=//p" $2 2> /dev/null
}
 
 
for i in `ls -c1 /usr/share/applications`
do
    CF=/usr/share/applications/$i
    name=$(param_val Name $CF)
    executable=$(param_val Exec $CF)
    icon=$(parm_val Icon $CF)
    categories=$(param_val Categories $CF | cut -d\; -f1)
done

gtk-update-icon-cache

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.
