| Most zip or tar archives are made so that they unpack into a sub-directory. However, every now and then you run into one that wasn't done that way, and if you happen to unpack it in a directory that already has files, you end up with confusion: what was just unpacked and what was already here? Of course an "ls -lt" gives you some idea, though not for directories: you'll need just "ls -l" to see recent dates for any directories created by the archive. For illustration, I created three empty files (a, b, c) in a directory and then unzipped an archive into it. The results of various "ls" commands are shown: $ ls -l total 17064 drwxr-xr-x 4 foo group 136 Oct 7 16:35 BuildFiles -rw-r--r-- 1 foo group 17984 May 5 2004 COPYING drwxr-xr-x 3 foo group 102 Oct 7 16:35 Cd -r--r--r-- 1 foo group 15377 Oct 14 2003 Citrix EULA.txt drwxr-xr-x 3 foo group 102 Oct 7 16:35 Floppy -rw-r--r-- 1 foo group 1099 May 5 2004 LICENSE drwxr-xr-x 5 foo group 170 Oct 7 16:35 RebuildIsoWithConf -rw-r--r-- 1 foo group 8684127 Oct 7 16:35 Thinstation-2.1.1-prebuilt-LiveCD.zip -rw-r--r-- 1 foo group 6263 Jul 28 13:01 _HowTo-LiveCD.txt -rw-r--r-- 1 foo group 0 Oct 7 16:35 a -rw-r--r-- 1 foo group 0 Oct 7 16:35 b -rw-r--r-- 1 foo group 0 Oct 7 16:35 c $ ls -lt total 17064 drwxr-xr-x 4 foo group 136 Oct 7 16:35 BuildFiles drwxr-xr-x 3 foo group 102 Oct 7 16:35 Floppy drwxr-xr-x 5 foo group 170 Oct 7 16:35 RebuildIsoWithConf drwxr-xr-x 3 foo group 102 Oct 7 16:35 Cd -rw-r--r-- 1 foo group 8684127 Oct 7 16:35 Thinstation-2.1.1-prebuilt-LiveCD.zip -rw-r--r-- 1 foo group 0 Oct 7 16:35 a -rw-r--r-- 1 foo group 0 Oct 7 16:35 b -rw-r--r-- 1 foo group 0 Oct 7 16:35 c -rw-r--r-- 1 foo group 6263 Jul 28 13:01 _HowTo-LiveCD.txt -rw-r--r-- 1 foo group 1099 May 5 2004 LICENSE -rw-r--r-- 1 foo group 17984 May 5 2004 COPYING -r--r--r-- 1 foo group 15377 Oct 14 2003 Citrix EULA.txt What a mess. There's no easy way to identify what came from this archive if we didn't already know. So, the easiest thing to do is to delete it and start over in a clean sub-directory. But how can you delete files if you don't know which ones should be deleted? Not so hard, actually. Try this: $ mkdir t $ cd t $ unzip ../Thinstation-2.1.1-prebuilt-LiveCD.zip Archive: ../Thinstation-2.1.1-prebuilt-LiveCD.zip inflating: COPYING inflating: Cd/thinstation.iso inflating: Floppy/thinstation.profile/thinstation.conf.user inflating: BuildFiles/thinstation.conf.buildtime.prebuilt-cd inflating: BuildFiles/build.conf.prebuilt-cd inflating: LICENSE inflating: Citrix EULA.txt inflating: _HowTo-LiveCD.txt inflating: RebuildIsoWithConf/rebuild-iso.bat inflating: RebuildIsoWithConf/mkisofs.exe inflating: RebuildIsoWithConf/cd-files/delme.txt $ for i in *; do rm -rf "../$i"; done $ cd .. $ ls -l total 16968 -rw-r--r-- 1 apl staff 8684127 Oct 7 16:35 Thinstation-2.1.1-prebuilt-LiveCD.zip -rw-r--r-- 1 apl staff 0 Oct 7 16:35 a -rw-r--r-- 1 apl staff 0 Oct 7 16:35 b -rw-r--r-- 1 apl staff 0 Oct 7 16:35 c drwxr-xr-x 2 apl staff 68 Oct 7 16:38 t All clean. The files are in "t" and the mess is gone. Unless there were "." files in that mix; this script doesn't touch those. Add .[0-z]* if you must.
