What does this do that the shell built-in read doesn't? A simple

read -s VAR

seems a good deal simpler than a mess of Perl.

(The -s flag puts it in silent (noecho) mode; other options let you show a prompt, time out, etc. It's available in sh, bash, zsh etc.)

And, as other posters have mentioned, if the result's going on a command line then it doesn't matter how you construct it, coz ps or top will see it anyway...

Well for one reason not to use read is that it does nothing from the command line.
<code>
% read foxhole
hello
% echo $foxhole
foxhole: Undefined variable.
</code>

You are wrong, this works perfectly well.
