/dev/null is to keep grep quiet... otherwise it would output the line that
matched. If you want to see it when a match is found, then you could take
that out. The break is there so when it finds a match it breaks out of the
loop, since there's no reason to keep looping once a match is found.
If you want to pipe the output of scs2ascii through this script, you would
have to do it like so:
#! /bin/bash
file=`cat /dev/stdin`
users="PHILLIP SAM RICHARD"
for user in $users; do
echo "$file" | grep $user >/dev/null && echo "$file" >
/home/misadmin/"$user"_`date
+%Y-%m-%d-%H:%m` && break
done

Toby,
That certainly worked for me. Would you explain the reason for
/dev/null and the break command? In the mean time, I will research it
in my book.
Also, will this script work by piping the output of scs2ascii to my
script? I haven't tried that yet. Here is the script, so far:
#! /bin/bash
file=/home/misadmin/ID-4892.txt
users="PHILLIP SAM RICHARD"
for user in $users; do
grep $user $file >/dev/null && cat $file > /home/misadmin/"$user"_`date
+%Y-%m-%d-%H:%m` && break
done
Something like this should work...
users="user1 user2 user3 user4 user5"
file=<name of file>
for user in $users; do
grep $user $file >/dev/null && cat $file > /tmp/"$user"_`date
+%Y-%m-%d-%H:%m` && break
done
