Prevent overwriting file when using redirection

If you set noclobber to on, bash won't allow redirection to overwrite existing files .

set -o noclobber command turn the option on (default it s off ) .

You can still append information but not overwrite the file .to turn it back off use : $ set +o noclobber .

I use it because i overwrite a file by accident , after thought , content of the file was very important , creating a one more file mean nothing for my hard disk (we are not anymore on the 64 k memory time) , but content of file is far much important . What we call exeprience :(

Alternatives

There is 1 alternative - vote for the best!

Know a better way?

If you can do better, submit your command here.

What others think

if you really need to overwrite a file when noclobber option is on, then do this (add pipe after ">"):
