Script for friendlier home partition under other OS

[Gábor Iglói]

Only one thing remained now:

To speed up things I should clear up before tarring ~/.thumbnails
containing several MB of image thumbs and Firefox's page cache. The
first is easy enough for me, but Firefox stores it's user spec things
under a "randomsequence".default folder under ~/.mozilla/firefox. I
managed to get this folders name with

user at ubuntu1:~$ cat /home/user/.mozilla/firefox/profiles.ini | grep Path=
Path=u8n5vr1q.default

But how can I cut out the "u8n5vr1q.default" string from that
command's output? I'd like to clear the
/home/user/.mozilla/"randomsequence".default/Cache folder from my
script.
