Change password with usermod

Hi,

I'm trying to set a password directly from a script, using usermod, but=
=20
i get an error, i shouldn't get:

#!Bin/bash
groupadd postgres
useradd -g postgres postgres
PASS=3D`mkpasswd secret`
ID=3D`cat /etc/passwd | grep postgres | cut -f3 -d':'`
usermod -p $PASS -u $ID

This gives me:
"usermod: user 502 does not exist"

But the odd thing is that it exists with that uid.

Any ideas ?

Warm Regards,
M=E1rio Gamito
