You can enter this at the command line if the Ruby interpreter is installed:

ruby -e "File.open("sourcefile").each_line { |line| system("command #{$1} #{$2}") if 
/(.*)t(.*)/=~line }"

Replace 'sourcefile' with your file 'command' with the command and flags you
want to run. #{$1} and #{$2} are the $x and $y, respectively.

This is my first one liner, BTW. :)
