By running: echo "set -e" >> ~/.bash_profile You can put your shell (well, at next login) into an enhanced error checking mode. This makes it much easier to detect when any program you run has errors thus allowing you to learn from mistakes and avoid making them again. It will also prevent you from accidentally using undefined variables, so "rm -rf $HOM/bin" instead of "rm -rf $HOME/bin" won't delete (or attempt to delete) /bin. The enhanced error checking has long been recommended for shell scripts, but don't miss the opportunity to benefit from it on the command line, too. Elijah ------ try also "set -C" for anti-clobber protection
