Szekely-Benczedi Endre spake thusly:
There is a nice small shell script at www.rootshell.com, longpath.sh, wich exploits some bug in Linux about long pathnames...
[snip]
I heard that it is possible to erase it with mc (Midnight Commander). Well, I can tell you' this ISN'T true ;-) I tried the script on a RedHat Linux, and... well... I can't erase the directory now ;-) I wonder if anyone of you knows the problem, and can help me with that..
#!/usr/local/bin/perl5 # this basically does an rm -r, only on directories. Be careful. :) $junk="junk.$$"; mkdir $junk, 0700 || die "$0: $!"; $seq=0; sub newseq { return ($seq++);} foreach (@ARGV) { rename $_, $junk."/".&newseq || die "$0: $!"; } chdir $junk || die "$0: $!"; $current=0; while ($current<$seq) { foreach (glob "$current/*") { rename $_, "./".&newseq || die "$0: $!"; } $current ++; } foreach (glob "*") { rmdir ($_) || die "$0: $!"; } chdir ".." || die "$0: $!"; rmdir $junk || die "$0: $!"; Just give it the name of the top-level evil directory (making sure to run it in the same filesystem), and it'll clean things up. Next time, be more careful.:) -- Mordechai T. Abzug "Grad school is the snooze button on the clock-radio of life." - comedian John Rogers (who holds a graduate degree in physics)
