*nix systems typically have a
locate utility installed. It has a database, usually updated nightly, that has the names of (almost) all files on your system. Just run:
and you should see a list of files that were in that directory as of the last database update. You can diff this against the current list.
Because it will be overwritten automatically with a new version, you might make a back-up copy of that database now. On debian-influenced systems, it is stored in
How to show missing files
Make a backup of the old database:
cp /var/lib/mlocate/mlocate.db ~/old.db
Update the database. The command to do this may vary. On a debian-like system, try:
Get the new and old file lists for your directory:
locate -d ~/old.db /your/dir | sort >~/old.list
locate /your/dir | sort >~/new.list
Get a list of all new and missing files:
diff ~/old.list ~/new.list
Not all files are listed in locate's database. A configuration file, typically
/etc/updatedb.conf, determines which files and directories are excluded.
In the past I have used some version of
locate that, by default, would only list files that still exist. If that is the case for your
locate, you will want to turn that feature off.
