I'd second that.

Note that grep's equivalent option is -h, --no-filename (no
plural).

Another addition could be --with-total, so that the total always
be included even if there's only one argument (as in wc
--with-total ./*.txt).

Note that the awk '$2 != "total" {print $1}' is not reliable
unless you can guarantee filenames don't contain newline
characters and are not called "total" or
"total[[:blank:]]anything".

A

  -Z, --null                print 0 byte after FILE name

like grep's (to pipe to awk -vRS='\0' or sed/sort -z for
instance) would help.

For now, one needs to do things like:

wc -l ./*.txt | awk '/\//{print $1}'

or

find .//. -name '*.txt' -exec wc -l {} + | awk '
   /\/\// {print $1}'
