[linux-help] Re: Quick BASH/Perl Question

[Steven Saner <ssaner@xxxxxxxxxxxxxxx>]

Since John answered the first question, I will answer the second.

There are a couple ways. Assume that the string is in $str and you
want the first letter in $val.

$str =~ m/^(.)/;
$val = $1;

or

$val = substr($str, 0, 1);

Might be more ways too
