Diff two command outputs (stdout) without using files
Raw
readme.md

Source: https://crashingdaily.wordpress.com/2008/03/06/diff-two-stdout-streams/

You can diff two commands stdout without creating two files. <( ... ) command creates a temporary file with the stdout of the command inside it.

Example:

diff -B <( ls -1 / ) <( ls -1 ~ )

<( ... ) enables you to use any stdout as a "file" input to commands that need to work on files (like diff does).
