I would like to grep all values other than encrypted password from /etc/shadow file. Could someone please help me?
For example,each line consists of 8 fields separated with :/
The only thing that I want not to print out is the contents between first : and second : (encrypted password)
Can someone please please help me???

No, post #2 is correct; OP wants everything EXCEPT field 2 (passwds).

So, should it be
cut -d ":" -f 2 /etc/shadow
???
or cut -d ":" -f 2 --complement /etc/shadow ?? doesn't complement converts my selection?? so it would just print out passwords?

Assumes there is always 8 fields...

Code:

awk -F ':' '{print $1,$3,$4,$5,$6,$7,$8}' < /etc/shadow

With the cut you want complement because if you're just selecting column 2 you'll get nothing but the passwords. By complementing the selection of column 2 you are saying everything but the passwords.
