I was not aware of this technique until recently... and yes I see also there are more use cases e.g. with `cp` and `mv`. 👍

E.g. cp a{,.bak} or me b{,.old}

I can never remember whether that you need a comma to separate items (because glob expansion produces spaces). If I tried to build that command I would get errors or subfolders called ; 😅

Like in any Script:

tempdir_for_script=“/tmp/tempdir_for_$(basename “$0”)

Later in the script:
<result to log> >> “$tempdir_for_script”

Last line of script:
# rm -r “$tempdir_for_script”

(Remove # after full debugging)

Once in a while I have some random insights that I deem worth sharing. However, while I write up those thoughts I usually doubt whether it is worth the effort...

Therefore, it is really nice to hear that one of those thoughts inspired you that much that you still remember it (and its provenience).

I highly recommend reading the man page of bash, it's all in there! It's loong though.
