Search in paragraph's text

Revision as of 21:11, 16 February 2022 by Poulteki (talk | contribs) (verify the presence of a word or regular expression within several paragraphs of text (structured or not))
(diff) ← Older revision | Latest revision (diff) | Newer revision → (diff)

The goal is to verify the presence of a word or regular expression within several paragraphs of text (structured or not) and to print the relevant paragraphs on the standard output.

Search in paragraph's text is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

So here, let’s imagine that we are trying to verify the presence of a keyword "SystemError" within the paragraphs "Traceback (most recent call last):" in the file Traceback.txt

cat Traceback.txt :
