In the below example you are saying if $gimp equals "gimp" or if "gimps".
The First part of the if is actually testing values while the second part
of the if statement is always true... therefore always printing working.
you could try
if ($gimp =~ /gimp/)
{
print "working";
}
The above example matches if the word gimp is found anywhere in $gimp.

| Subject: needing help with the or, || operators
|
>------------------------------------------------------------------------------------------------------------------------------|
I've been coding some basic programs learning perl and I'm having some
problems with the or operators. Here are a couple coding samples if anyone
knows what I'm doing wrong with this please tell me.
#!/usr/bin/perl
$gimp=<STDIN>;
chomp ($gimp);
if ($gimp eq "gimp" || "gimps") {
print "working";
}
print "\n";
With this one I'm trying to just print out the string "working" if the user
enters either "gimp" or "gimps". No matter what is entered here it still
prints out "working" though.
I've also replaced the "||" with "or" in that last example but it does the
same thing.
I can fix the program with either this bit of code:
#!/usr/bin/perl
$gimp=<STDIN>;
chomp ($gimp);
if ($gimp eq "gimp") {
print "working";
} elsif ($gimp eq "gimps) {
print "working";
}
print "\n";
or this one:
#!/usr/bin/perl
$gimp=<STDIN>;
chomp ($gimp);
if ($gimp eq "gimp" || $gimp eq "gimps") {
print "working";
}
print "\n";
Is this a problem with the or operators or do I just always have to specify
$gimp eq "string1" || $gimp eq "string2"? I would think you would be able
to
just leave off the second $gimp eq.
