How does one go about using diff to compare the output of two commands?
I know how to use it to compare the contents of a file filename1 with the output of a command cmd2:
cmd | diff filename -
How do I make it so that I can have another command, say cmd1 in place of filename?
I'm using dash, which doesn't support process substitution.
diff stdout dash
