Echo a command, then execute it

v () { echo "$@"; "$@"; }
You can use this in shell scripts to show which commands are actually run. Just prepend every "critical line" with "v˽". $TMP=/tmp echo "Let me create a directory for you" v mkdir $TMP/new In scripts this can be more useful than "set -x", because that can be very verbose with variable assignments etc. Another nice use is if you prepend every "critical" command with "v", then you can test your script by commenting out the actual execution.
Sample Output
$ v rm -v *~
rm -v example~
removed `example~'
