See, sometimes learning a proper language can help do certain things, i.e. a
full singing all dancing interface... however other times its easier just to
make a bash script, because all your wanting to do already exists in
several, well designed, individual tools that linux/gnu have provided us
over the years. In fact I know many people who make bash scripts, or use
linux/gnu tools, and then wrote up an interface in python to use said
scripts - just so it looked nicer for the user... sometimes this is all you
need! Why re-write something that already does the job, and does the job
well! For example `grep`, I don't think I would even TRY to recreate that,
there's no need... or `sed`... `wget`... `lsof`... `find`... etc... these
tools are fantastic, people should use them! I mean, many before us have
spent years making and perfecting them, why let them go to waste. So yeah, I
fully agree with you - never listen to someone who says "learn a proper
language" - scripting is there to help people, why should we deny them that
right as linux users.


Actually I'm down towards Barrow. Funny, but it's less miles to Carlisle

Manchester is a lot further away from me to be honest, so would be a pain to
get down there... also, Barrow isn't that far away... I've went there and
back a few times... think the main thing is that you have that lovely road
that goes across (fantastic view of the river/trees/lakes/etc)... and then
after you've got the boring M6 up (Carlisle) or down (Manchester). So I know
what you mean by it feeling like its a lot longer than it is.
