in reply to Re: Baby Steps
in thread Baby Steps "if" behavior?
'exists' is used to find out if a hash key exists,
this is needed because perl will create a key/value pair even if
you are just 'seeing if it's there'. (e.g, its
not use on scalars as such)
also, the -e (and friends) flags are file test operators
where parameter is the name of a file.
if (-e /mnt/dos/command.com)
{
print "good choice, show who's in charge\n";
}
see 'perldoc perlfunc' for a list of the file tests you can perform.
