Question

I have to find all initializations (captial letter words, such as SAP, JSON or XML) in my plain text files. Is there any ready-made script for this? Ruby, Python, Perl – the language doesn’t matter. So far, I’ve found nothing.

Regards,

Stefan

Answer 1

Here you go:

perl -e 'for (<>) { for (m/\b([[:upper:]]{2,})\b/) { print "$1\n"; } }' textinput.txt

Grabs all all-uppercase words that are at least two characters long. I use [[:upper:]] instead of [A-Z] so that it works in any locale.
