Hi, Thank you for your answer.
usermod needs a login name rather than the userid and you don't need -u option: # usermod -p $PASS postgres
I tried that but didn't work for me: "[root@mail ~]# usermod -p $PASS postgres usage: usermod [-u uid [-o]] [-g group] [[-a] -G group,...] [-d home [-m]] [-s shell] [-c comment] [-l new_name] [-f inactive] [-e expire ] [-p passwd] [-L|-U] name"
However, I usually user chpasswd to change the password from a script, so your script becomes: # echo postgres:secret | chpasswd
But this does :) Thanks a bunch. Warm Regards, Mário Gamito - To unsubscribe from this list: send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
