I wouldn't think so. You don't know where your script will be called from, and many times the parameters to the script are file paths, which are relative to the caller's path. So you usually don't want to do it.

I collected many tips&tricks from my experience with shell scripts that you may also find useful: https://raimonster.com/scripting-field-guide/

I agree. I make an effort to not change directory wherever possible and if a change is needed, do it in a subshell and just for the command that needs it (hardly any commands actually need it, anyway).

Edit: just had a quick look at your recommended link and spotted a "mistake" in 4.7 - using "read" without "-r" would get caught out by shellcheck.

Fixed, thanks!

In e.g. "Read the great Oil Shell blogpost." it's not clear there's a link there: the "blogpost" is a link but you only see that if you hover your mouse.

Oh, I hadn't noticed that links are not highlighted as such (unless already visited).

Fixed, thanks!
