Top Forums Shell Programming and Scripting How to switch user in shell scripting (without root)? Post 302964867 by rbatte1 on Wednesday 20th of January 2016 09:17:13 AM

The sudo tool is designed to give you the choice and it is probably the best way.

Incidentally, you should not really try to force the password in like this. If you have a process to run that is automated, i.e. you don't fire it off as a real person on the command line, then you should really run it as a non-personal account. You can then give that account the sudo privilege to not require a password.

The problem is that if you script this, then anyone able to read your script will know the account password. Additionally, good practice would have you changing the passwords regularly and that might require editing every script each time.

How far have you got with this now?


Kind regards,
Robin

dxchpwd(1X)															       dxchpwd(1X)

NAME
dxchpwd - Create or change password program SYNOPSIS
dxchpwd dxchpwd -r | -l dxchpwd [-r | -l] -q dxchpwd [-r | -l] -u username OPTIONS
If dxchpwd is invoked without any options, it is assumed that the current user's password is to be changed. The following options are also accepted: Tells dxchpwd that the password change is to be done for a Local user. This can be combined with the -u and -q options. Tells dxchpwd that the password change is to be done for a NIS user. This can only be done from a NIS master and can be combined with the -u and -q options. Tells dxchpwd to query the user for the user name of the account whose password is to be changed. Tells dxchpwd to change this user's password. DESCRIPTION
The dxchpwd command lets you change your password. When you invoke the dxchpwd command, the program prompts you for the old password and then for the new password. Next, the program asks you for the new password again, to verify that you have typed it correctly. Note that the passwords are not displayed on the screen. Your new password must meet the length requirements specified by the authorization database for the user whose password is being changed. If your system is running with enhanced security, you may have to choose a password from a list of randomly generated passwords or you may be prohibited from changing your password until its minimum lifetime has expired, as specified in the authorization database. EXAMPLES
The following example requests that the password be changed for user smith: dxchpwd -u smith FILES
Password file Protected Password Database dxchpwd executable SEE ALSO
X(1X), xdm(1X), passwd(1) dxchpwd(1X)
