[SOLVED] How to change login password in BASH script?

I found 

 # echo "somewords" | passwd --stdin username

won't work. So what should be used instead of that option "--stdin " ? Or do you have any other way of doing it？

Where did you get "--stdin" from?  passwd reads from stdin by default.  But you do need to enter the password twice.  I don't know if this is the best way, but this works:

printf "somewords\nsomewords\n" | passwd username

Actually there is a tool specfically for scripted password changes: `chpasswd`.  Use that:

echo username:somewords | chpasswd
