Line number exit outpu command ? #126

Hey guys,

Is there any way to display, for example, the number of lines in the output of a command?

Ex.

$ ls 1 file1 2 arch2 3 arch3

There's the nl command, or equivalently a custom bit of Bash could do the same in a few lines, but I don't think there's any way to hook into the pipeline like this at the time(s) bash-preexec is running without somehow modifying the command itself.
