Dear Gilbert,
I have replaced wc with make install from /usr/src/usr.bin/wc and now it
works. Up now wc -l gave no results, now it give proper number.
Could you, please, explain the following line: [ $n -gt 0 -a $rc -lt 1 ] ???
Why are there [] ? When I write it at prompt as
[0 -gt 0 -a - lt 0] it writes [: 0: unexpected operator, but
[0 -gt 0 -a -lt ] writes nothing.
What is it ? What type of command is written such kind ?
Peter Rosa
P.S. Now awk -F: '$3==0 {print $1,$3}' /etc/master.passwd | tee /dev/stderr
| sed -e '/^root 0$/d' -e '/^toor 0$/d' | wc -l returns
root 0
toor 0
1
