diff two commands
by Tyler on Jan.17, 2011, under Programming, scripting
Ran across this problem with a friend today. How does one diff the output of two commands without first dumping the output of the two commands to files? I found a solution that seems to work:
diff <(command1) <(command 2)
Suppose we wanted to diff the contents of two directories:
diff <(ls directory1) <(ls directory2)
