This tip is for people who have ever hosed important files by using > when they meant to use >>. Add the following line to .bashrc: set -o noclobber. The noclobber option prevents you from overwriting existing files with the > operator.

Code Listing 1


% program > file2
bash: file2: cannot overwrite existing file

In some cases you may really want to overwrite the file. In this case, instead of turning noclobber off, you can use >| to force the file to be written.

Code Listing 2


% program >| file2
