Question

I am writing my first ever Shell script today. I think I have found everything I need online but need help on one thing:

I want to be able to pass a couple of optional arguments when the script is called: e.g myscript.sh -filename somefilename -location some/file/location -deleteoption yes

all them 3 options are optional so I need my script at the very first stage to loop through each argument and then depending on the descriptor of the argument (e.g -filename) store the value (somefilename) in to the correct variable?

another thing is that the options can be given in any order.

How do I go about achieving this functionality?

If you’re using bash, you might want to use getopts. Otherwise, googling for “shellname option parsing” should return something similar for your shell of choice.
