perl-rename 's/b(\d{2}A)/\1/' * finds and renames every part of any file with

  1. "b" followed by

  2. 2 digits followed by

  3. "A"

Is there an option or way to make the regular expression case-insensitive, i.e. also matches either an uppercase "B" for the first part and/or a lowercase "a" for the last part?

    Can you provide some samples? its not clear what you mean by "an uppercase "A" for the first part and/or a lowercase "a" for the last part?"

  • Is [aA] what you're looking for?

  • @Kusalananda Yes. The matching works then. If you provide your comment as an answer, I can mark it as solved.

  • @Inian I made a mistake with the "uppercase "A"". It should have been "B" instead. I genuinely thought the enumerated list was self-explanatory.

The s/// substitution command in Perl (and thus in the Perl rename command) has a flag /i to do case insensitive match. All you need to do is

perl-rename -n 's/b(\d{2}A)/\1/i' *.jpg

Remove the -n flag when you identify the files are renamed as expected. It only does a dry-run to show how the files will be eventually renamed.

To selectively allow case insensitive matching of one or several characters, use e.g. [aA] (will match either a or A).
