Hi!

I'm a bit noob on Unix/Linux world, so sorry any lame question i may make...
Oh.. and my english too.. is not so famous lol..

The deal is to use crontab to change my admin password every weak to something like "mypasswordcurrrentday" that is... i want evey weak to change my password but only the current day... for example

Fryday 6
mypassword6

Fryday 13
mypassword13

Fryday 20
mypassword20

I know i probably have to do a Shell Script but i don't think thats the problem i just need someone to indicate me what command i should use, because i can't seem to do it... If anyone knows something similar it would be usefull to.

Thanks in Advance.

command passwd lets you change the password. crontab -e will help you in setting the cron job. You may have to use Expect in your script to feed password to passwd command. But then the script used in the cron job would expose your logic of making the password (unless it is a compiled script or program).

Consider the security risk before implementing this feature.

Using expect in this way may help you, but as Yogesh pointed, there will be a security risk by exposing the logic. Why changing the password in this manner is needed ? Does anyone else has root access to this machine ?
