One of the nice parts about shell is that you can quickly prototype things. But eventually they become too brittle or limited or complex and you need to switch to a better langauge. Pipelines are powerful, but real data structures are better.
The brevity is nice though. From the ia-save
script,
these four lines of shell…

…become twelve lines of python. The data in the python version
ends up in a set (in this case accomplished by a dict
) which makes
it easier to work with than the stream it’s in for the shell version.
In addition it’s easy to see how to give it a list of urls to not save.

Sometimes “more” code is better.
