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 :(
