Actually, no, '==' could not be used. Witness this code:
$abc="b";
print "yes\n" if ($abc=="b"); # appears that == works
print "yes\n" if ($abc=="e"); # shows that == does not work
Output:
yes
yes
To do string comparisons, you must use 'eq', 'ne', etc.
$abc="b";
print "yes\n" if ($abc eq "b"); # appears that 'eq' works
print "yes\n" if ($abc eq "e"); # and indeed it does
Output:
yes
