Go to your backups and restore the file.
Anything else will require filesystem reconstruction and depending on 
much the filesystem has been used since, it may not work.
For such a reconstruction you would need to have an in-depth knowledge 
of the filesystem structure.

Assuming it's an ext2 filesystem:

	/usr/src/linux/fs/ext2

Also, the source code for the programs in the e2fsprogs package.

I can't recall if it deals with filesystem reconstruction, but for a 
good read on the topic you should get hold of
UNIX Filesystems by Steve Pate. Also search google for fsdb (the 
filesystem debugger).
For a more Linux twist on things, I could recommend Understanding the 
Linux Kernel by Bovey & Cesati.

I recommend Midnight Commander (mc), which has a function in it which
undeletes files for the ext2 filesystem.

There is also a howto called the Ext2 Undeletion HOWTO, as well as a Ext2
Undeletion Dir Struct HOWTO. These give you the methods step by step, though
they are a bit dated. In theory they will work with ext3 (if you unmount it
cleanly).

If you are just looking for a setup that lets you undelete a file (e.g. you
haven't deleted it yet but think you will) you can use libtrash. This is a
preloaded library which uses hacks to hide files instead of deleting them
(it does the override at the library call level, so only staticly linked
binaries can delete files). This is as good as you can get w/o patching the
kernel.

Look in your home directory for the tmp directory.  Some distributions
link the rm command to the mv command and actually move a file you delete
into HOME/tmp rather than actually erasing the file.

It's also possible that any file you rm is actually moved someplace else.
You might want to check your personal and/or system login-in files
(/etc/profile, HOME/.profile, HOME/.bash_profile, etc) for pertinent alias
commands and such.
