Hi...
I want to write a shell script to change my password and I want that password to be picked up from a file and I'm not supposed to type anything once I run that script and change the password.Is it possible...if yes please send me the solution.

Thanks in advance,

man chpasswd
But it's not really a good idea :)

Cheers,

Hi Gurus ,

I am a new member to this group and also a novice user for unix . I have to write a shell script which can change the password of a userid four times. I want that it should read the first 3 passwords from a file . The fourth time the password will be the one which was in the beginning .

Kindly help me .

Regards,
Satya

Looks like I'll need a script to do this same thing, as well, I'm seeing. I found one thing that doesn't work.

Code:
passwd < [file name]
I'm trying to do this for another similar reason as you guys. I'll check out that man page too. It might work for me.

Sounds like this exercise may be part of the curriculum of some similar course the three of you are taking when considering the quote below.

And now, I've found what does work for me, in my limited case of what I needed. If this solution works for you too, then here it is:

Code:
echo [passwd] > /tmp/[password file]
passwd --stdin [user] < [file with password]

When I found this, by the way, it was after looking up chpassword, and I couldn't make it work for me, for some reason.
