while(<>)  {
        print "yes\n" if /(^y$|^yes$)/i;
}

So could `while(<>) { print "yes\n" if /^y$/i \|\| /^yes$/i; }` [download] `while(<>) { print "yes\n" if /^y$/i; print "yes\n" if /^yes$/i; }` [download] By the way, useless capturing greatly slows down pattern matching.	[reply] [d/l] [select]
