Trying to extract a field from /etc/passwd file..
Hello, was looking for some help on extracting a field from the passwd file.
So far I have made a copy of the passwd file and changed my rights so I can edit it. Every user's password is coded as an :x:, and my goal was to change that x to a blank, and then try to extract any user with that field is blank. So far I've tried grep '^[a-z]::' passwordfile. Which doesn't seem to work. Any ideas would be greatly appreciated.Thanks!
STEVE...

Code:
sed -e 's#\(.*\):x:\(.*\)#\1::\2#g' /personal/etc/passwd

What are you trying to do ? Extract the blank field ? Or extract the user whose password field is blank ? Smilie
