I was just trying to match a string and save it in a single statement
as follows:
$extracted = "cp xyz";
$state_var = $extracted =~ m/cp\s+(.*)/;
print "$state_var $1 \n";
The output is: 1 xyz
So the assignment to $state_var does not work. Is this an incorrect
way.
In scalar context a match returns true if it matches or false if it
doesn't. You want to use list context to cause the match to return
the captures:
($var) = $foo =~ /(blah)/;
It's not required, but this is one of the places where I would use
explicit braces.
($var) = ($foo =~ /(blah)/);
Not so much because the left hand side is in braces, but because I'm
never really sure which one, = or =~, has higher precedence.
There are no braces {} in that expression. See:
http://en.wikipedia.org/wiki/Bracket
for the correct nomenclature.
