I am looking for an explanation how
grep --label=LABEL works: Maybe somebody can give me an example [or two] on what
--label= is for.
I understand what
zgrep are supposed to do – the latter is mentioned in the entry on
--label= in the
... especially useful when implementing tools like `zgrep'
98% of what I found so far is copy/paste from
info grep and the other two percents the command is embedded in a script which I don't understand.
