I believe the function I posted earlier should work for all these cases.
Pb with space wc -l Because I don't have the space problem, I made a slightly different wc function for testing here. Code:
vnix$ type -all wc
wc is /usr/bin/wc
vnix$ wc () {
> set -- `/usr/bin/wc "$@"`
> echo $1
> }
vnix$ wc /etc/motd
8
vnix$ wc -l /etc/motd
8
vnix$ /usr/bin/wc /etc/motd
8 50 338 /etc/motd
vnix$ wc -l </etc/motd | cut -d ' ' -f1
8
vnix$ if [ `wc -l </etc/motd` -eq 8 ] ; then echo foo ; fi
foo
vnix$ F=/etc/motd
vnix$ wc -l $F | awk '{ print $1 }'
