diff

[אורי]

Hi,

Actually I prefer the "<(..)" method, because sometimes I want to compare 2
commands:

diff <(pip freeze | sort) <(cat requirements.txt | sort)

Or even use cat and echo to add a specific line to one of the outputs. If I
want the result to be completely null. For example to run in crontab and
send me mail whether it's not null.
