etc/passwd edition

[Theadmin77]

Ok , i need to make some changes on user password policies by editing the etc/passwd file ...

I need to change joeblow /etc/shadow entry so that he must change his password once every 90 days, receiving a warning 5 days prior to his password expiring, with no minimum time before user can change his passwords .

So far i can accomplish the first part (90 days to change password) thru this command:

chage -M 90 joeblow

But i am a little stock with the rest .

Any idea anyone ?

I appreciate any help

you do not want to manually modify your /etc/shadow file. use the proper tools, like usermod or passwd to change them. check your passwd, usermod man page for instructions.
