In Using Perl saves time....:
ls -1 | wc
In Re: Using Perl saves time....:
Why did you use -l for the ls?
I think your computer is not showing you the difference between a digit one and the letter ell. The original post is an (unnecessary) digit one. You're complaining rightly about the expense of a letter ell long listing (if that was indeed the case).

It's unnecessary because ls has two behaviors, depending on whether the output is a terminal or not (something I count as being broken, but oh well). To a terminal, it columnizes, but to a pipe or file, it's automatically one element per line (classic mode). Thank the idiots at Bezerkley for this abomination. This leads people to believe that they need to add "-1" to get one column, when in fact that's usually not necessary.

As an example, compare "ls" with "ls | cat".
