How to recover a file overwritten with another in Linux? [closed]

Question

I did this on the command line(Ubuntu 12.04)

mv some_arbit_file required_file

Is there any way I can recover required_file. I had put so much work into this. I usually backup files. But, I forgot this time. Will appreciate any help.

Thanks.

You can't "undo" your command. Maybe you can found some recovery tools that will help you...

By the way the next time, to avoid this kind of trouble I suggest you use the -i option. It will tell you if you're going to overwritte a file.

You can create aliases in ~/.bashrc :

alias mv="mv -i"
#you can also add aliases to cp and rm
alias cp="cp -i"
alias rm="rm -i"
