So depending on your filesystem you may or may not get it. LOGFS (or any log structured file system) : They generally have snapshots or some kind of file versioning. So you can retreive it from there. ext2 : After deletion ext2 doesn't zero the block pointers. So it is possible to get it from there using debugfs. ext3 : Search google for "Carlo wood + ext3grep" ext4 : I don't know of any method ... You can try the /proc/****/fd/** approach . It has worked for me in past......but that was for a running binary. I am not sure about shellscript kind of thing. There are some other tools too to recover , unfortunately I don't remember the name but google should be good enough.
