Please try to post in plain text. Thanks.
Do you really want $prmpt to be true if $_ matched your pattern,
and false if it didn't? Perhaps you meant "=~" instead of "=".
What exactly is Perl's "complaint" about your pattern? I have a
few suggestions:
o Use a different pattern delimiter if you want to match
forward slashes, to avoid the "leaning toothpick"
phenomenon.
o You don't need to turn a single character into a
character class: remove the brackets from the "[:]".
o Unless you need $1 later, you don't need parentheses
around the whole pattern. My guess is that Perl
didn't like having the "start" anchor inside parens.
Rewriting your pattern, then, I get this:
$prmpt =~ !^(.*:/home/oracle[:=>]{1,2})!;
$prmpt = $1;
Is that what you really meant?
Good luck,
Joe
