       @b0rk_reruns @b0rk Does anyone have any good way of remembering what each of these syntaxes do? Each time I use them, I have to look it up in the docs to make sure I'm using the right thing.How do you remember which of ${var#pattern} or ${var%pattern} removes a prefix or a suffix?I have such a hard time remembering I look it up each time. Anyone have some tricks for remembering?

       @tomjennings @b0rk_reruns @b0rk I guess "man bash" followed by "/suffix" will find it for you; I have usually skipped the Bash man page as I seem to recall it just being a stub that pointed to info docs that were too hard to search, but maybe I'm misremembering or maybe they've finally decided to give up the GNU crusade against man pages.
