Hi,
I would disagree. While I am more apt to use perl or gawk for one liners
there have been several times it has been nice to use ruby for oneliners.
They aren't just for showing off, they are often nice for quickly filtering
a file or something, and I have never bothered to learn sed over simple
replacements so one liners become quite useful in this regard. While most
of the one liners I have written haven't required the special characters to
do this I don't think dismissing one liners as simply for showing off is at
all fair.
Long term scripts shouldn't require one liners but for quickly scanning for
some info from a file or some basic filter one liners are what makes UNIX so
incredibly useful to programmers.
