Question

On busy days,I'd like to run

$./configure && make && sudo make install && halt

on the night and go to bed,hoping the application would automatically installed.But what I see the next days is the screen where sudo ask me for the password.So how could I run sudo with password in one command line or is there any other method to do this?

thanks.

Answer 1

Yes, use the -S switch which reads the password from STDIN:

$echo <password> | sudo -S <command>

So for your case it would look like this:

$./configure && make && echo <password> | sudo -S make install && halt

of course, replace <password> with your password.

Answer 2

You could replace your command line with this:

$sudo su

$./configure && make && make install && halt

You will be prompted for your password immediately, then the rest of the commands will run as superuser.

Answer 3

You could also configure sudo with visudo to allow you user to use make as sudo without password.

User_Alias USERS = your_user
Cmnd_Alias CMDS = /usr/bin/make
USERS ALL = (ALL) NOPASSWD: CMDS
