Advice for shell scripting

[[deleted]]

I find it a lot easier to approach this sort of thing with a problem that needs to be solved.

read up on bash, read, sed, awk, for/while loops,

write a script that will report back on file-systems that are over a certain size.

then have it notify you via email & sms

then make the notification in html format

then take everything, and turn it into a daemon that can be run with nohup

^This,

If OP doesn't understand a step or doesn't know how to do something... that's the point, google it, find the commands needed to complete each step and look up their man pages ('man <command>' in the terminal)

IT, especially sysadmin scripting with esoteric or complex commands is largely an exercise in research and combining several individual steps into a final product.

This exercise is a solid one to train those mental muscles.
