Find removed files still in use via /proc

Oracle DBA remove some logfiles which are still open by the database and he is complaining the space has not been reclaimed? Use the above command to find out what PID needs to be stopped. Or alternatively recover the file via:

cp /proc/pid/fd/filehandle /new/file.txt

Alternatives

There are 3 alternatives - vote for the best!

Terminal - Alternatives
ls -l /proc/*/fd/* | grep 'deleted'| grep "\/proc.*\file-name-part"

Accidentally deleted some file while used by a program ? (Eg: a song)

Use this command to find the file handle and recover using

cp /proc/pid/fd/filehandle /new/recoverd-file.ext

Know a better way?

If you can do better, submit your command here.

What others think

This will also work with:

# lsof | grep deleted

lsof is more efficient for finding files open files.

But for quickly finding files that can be "undeleted", i.e. that are opened, so their content is recoverable, this command is great. Thumbs up.
