sudo with password in one command line?

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?

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 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

Answer 3

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 4

Setting up sudo like that is dangerous if someone happened to see the fact that sudo requires no password on your account. Unless you know what you are doing, don't do that. I've had it happen at my local A+ Training program with my experimental computer one too many times... -_-

What John T. said sounds good though, except there still is the risk of finding the password in shell history. What CarlF said sounds better, but if one command fails, the computer will still be running with superuser privileges.

Answer 5

If you want to take more care, you could make a script, change the permissions of the file so only root can read and edit and then just run it.

Example:
1) Create a file:

gedit ~/.easy.install  

2) Paste this and save:

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

3) Make it executable:

sudo chmod +x ~/.easy.install  

4) Change the permissions of the file so only root can read and edit it:

sudo chmod 700 ~/.easy.install  

5) Run:

~/.easy.install  

Enjoy ;-)
