Hello CodeForces, today I tried solving an output-only problem for the first time but had lots of difficulties with bash scripting to create zips, direct input-output and stuff like that. I have always memorised the stress testing code from Errichto's amazing yt video on stress testing and since it is quite short it has served me well upto this point and so I never learned bash scripting. But now I really started thinking that I should learn it to solve output only problems. I'd like to hear your thoughts on the matter and get some nice links or resources.

Thanks for your attention
