[Klug-general] auto-delete menu entries as part of a bash script

[James Morris]

You can use sed with a regular expression:
sed  '\|\[exec[]]\s[(]\(.*\)[)]\s[{]/usr/lib/xscreensaver/\1
-root[}]|d' path/to/menufile

the above command output the menufile to stdout minus matching lines,
it assumes no variation in spaces between the { and } characters from
the example you showed.

once you have confirmed that it works and is not removing lines which
you do not wish removed, pass the -i option for it to edit the file
proper.

i've tested it in debian, using the following file:

----8<--------8<--------8<--------8<--------8<----

[begin] (Fluxbox 1.3.5)
[encoding] {UTF-8}
      [exec] (xterm) {xterm}
      [exec] (firefox) {firefox}
      [exec]   (Run) {fbrun}
[submenu] (Terminals)
      [exec]   (xterm) {xterm}
[end]


[exec] (foobar) {/usr/lib/xscreensaver/foobar -root}
[exec]  (foobar1) {/usr/lib/xscreensaver/foobar1 -root}
[exec] (foobar)   { /usr/lib/xscreensaver/foobar -root }
[exec] (fooba3r)  {/usr/lib/xscreensaver/fooba3r  -root }
[exec] (bar) {/usr/lib/xscreensaver/bar -root}
[exec] (barf) {/usr/lib/xscreensaver/barf -root}

----8<--------8<--------8<--------8<--------8<----

note it won't remove the menu entries with the extra spaces between  { }.
