Hello :),

Thanks for your hard work :)
I had a need for a variant of wordcount without filenames in the output,
tuesday.

https://github.com/LLyaudet/DevOrSysAdminScripts/commit/f0cb3291de4ad0bc63e40baf31364d1af6849f12
I started to make a patch on GNU coreutils on that day,
but I had to interrupt and continue today.
Here is the patch joined to this email.


Best summary of the feature is just to copy-paste my commit message:
wc: Add an option -n --no-filenames.

wc now has an option -n or --no-filenames to remove the filenames
from the output lines.
It is useful when used in conjunction with a single option
-c, -m, -l, -L, or -w,
since the result is a single number per line that can be easily used
in shell (Bash) scripts,
without having to pipe the result with cut.

doc/coreutils.texi: Add option -n to documentation.
NEWS: Mention the change option -n added and justify it.
src/wc.c: Modify the source code to have an option -n.
tests/wc/wc-no-filenames.sh: Test --no-filenames option for wc.


Note that it should be a -f --filenames option if the default was different.
If the default was configurable,
then we should have -f --filenames -n --no-filenames options,
like is possible in some of the latest versions of argparse in Python
(argparse.BooleanOptionalAction).
I don't know how to handle that in C code.
Please accept my patch and improve upon it if needed.

Best regards,
     Laurent Lyaudet
