Redirect stderr to stdout

Very simple, just remember:

• 1 = stdout
• 2 = stderr

In python, its

unittest

module loves to dump test results to stderr (rather than stdout). In order to pipe the results to

less

, you may need to redirect stderr to stdout:

python eggtest.py 2>&1 | less

To redirect stderr into a file:

python eggtest.py 2> result.txt

To redirect both stdout and stderr into a file:

python eggtest.py &> spam.txt
