Bilal Muddassir forced the electrons to say:
> bilal:/home/bilal $ cat ./test
> #!/bin/sh
> echo `date` `finger @$1|grep -v $1|grep -v Login|wc -l` $1 \
> | awk '{print $8" ---------- " $7" user(s) present on "$2" "$3" at
> "$4}
May I offer a suggestion?
awk in itself is very powerful, and perform the functions of grep and wc on
its own. So a simpler version will be:
finger @$1 | awk -vnum=0 ' /./ { num++ } END { print num - 2 } '
(The -2 is for the two lines that appear at the beginning of finger o/p - one
with the machine name and the other, a header line.)
This works even if somebody has a login ID as 'Login'.
Put the o/p of the above in a variable, and if it is < 0, finger failed
(connection refused). For other values, print out the string you want.
