google, where does $A get it's value in your script? Or do you mean that it should be used inside the loop? If it is, then you're doing a ton more work reading the file again in each iteration of the loop..
kevin, if all you want to do is display the names, part of google's script will work for you with a small addition:
Code:
awk -F: '{print "Found " $1}' /etc/passwd
If you want to operate on each name, you could use this:
Code:
#!/usr/bin/bash
while read A
do
USER=`echo “$A” | cut -f 1 -d “:”`
echo “Found $USER”
done < /etc/passwd
But I still think your initital problem was using single quotes by mistake...
