in reply to perl grep clone

# 5 0 5 0 3 print grep/$ARGV[0]/,<>; [download]
This dosen't work for me because perl tries to interpret the pattern as a file name, but I found it does not use this behavior when using <STDIN> instead of <>.

# 5 0 5 0 5 9 print grep/$ARGV[0]/,<STDIN>; [download]
print grep/@ARGV/,<STDIN>; [download]
