without this option, control of when the total is output
is quite awkward. Consider trying to suppress the total line,
which could be achieved with something like:
wc-no-total() { wc "$@" /dev/null | head -n-2; }
As well as being non obvious, it's also non general.
It would give a non failure, but zero count if passed a file on stdin.
Also it doesn't work in conjunction with the --files0-from option,
which would need to be handled differently with something like:
{ find files -print0; printf '%s\0' /dev/null; } |
wc --files0-from=- |
head -n2
Also getting just the total can be awkward as file names
are only suppressed when processing stdin, and
also a total line is only printed if processing more than one file.
For completness this might be achieved currently with:
wc-only-total() {
wc "$@" |
tail -n1 |
sed 's/^ *//; s/ [^ 0-9]*$//'
}
