Great idea!

Don't forget to make .preexec.bash executable, just "chmod +x .preexec.bash"

unfortunately, I just get "-bash: preexec_install: command not found" when I start a terminal. the .preexec.bash seems to be fine, I see the function defined -- are we sure this works with the default bash setup and default terminal on Tiger?

I don't think sourced shell init files need to be executable. .bash_profile isn't. I didn't make .preexec.bash executable, and it works for me.

But I do have the unhelpful "Some command" message.

function preexec () {
	export PREEXEC_CMD="$BASH_COMMAND"
	echo "DEBUG: PREEXEC_CMD set to '$BASH_COMMAND'"
	export PREEXEC_TIME=$(date +'%s')
}
