Hi, leider "passwd" command in einer Script zu benutzen ist nicht möglich. Dafür habe ich ein C code, compile it, und danach kannst du von deine shellscript abrufen ...
Usage: # chpwd <user> <password>
chpwd.c

/*
chpass - change a user's password from a script
Use the following command to compile:
# cc -o chpass chpass.c -ls

#include <pwd.h>
#include <usersec.h>
