The part you may have overlooked is the 'cut' command at the end of
$ cat crontab | egrep '^[0-9\*]' | cut -f3-

'egrep' selects the relevant lines (but the _complete_ lines)
'cut' cuts away a part of the lines (that where previously selected with egrep)

Anyway, using one of the proposed ruby variants will be much simpler
(and more on-topic ...).
