Follow-up Comment #4, bug #54730 (project findutils):
I agree. I'm trying to find a good example.
What about the following?
---------------------------------------------------------------------------
Find the name of a file in the current directory (and below) which contains
the word "needle", and stop when the first such file is found.
# Prepare 4 files, 2 of them contain the word "needle".
$ touch a b c d
$ echo needle > b
$ echo needle > dc
Without -quit, 'find' would call 'grep' for every file (and there's
currently no option to make 'grep' stop after a match across files):
$ find -type f \
-printf 'Checking: %p ...\n' \
-exec grep -FH needle '{}' \;
Checking: ./c ...
./c:needle
Checking: ./d ...
Checking: ./a ...
Checking: ./b ...
./b:needle
With -quit, 'find' stops after the first match:
$ find -type f \
-printf 'Checking: %p ...\n' \
-exec grep -FH needle '{}' \; \
-quit
Checking: ./c ...
./c:needle
--------------------------------------------------------------------------
