Executing commands in a series in ubuntu terminal

Suppose I have a set of commands to be executed in ubuntu terminal: for eg:

sudo apt-get update sudo install xrdp sudo install java .....

and many others.

Is it possible in ubuntu to execute the file containing these commands and execute without human intervention (like yes/no) , by default yes?

I tried installing wine , executing $wine cmd /c Commands.bat , after putting all these commands in .bat file but getting errors "Application tried to create a window, but no driver could be loaded." So, is there any simple way of executing a series of commands in ubuntu?


What you are talking about - multiple commands in one file - is called a "shellscript".

Let's say you have commands.sh:

sudo apt-get update sudo install xrdp sudo install java

Then you could execute the commands using:

bash commands.sh <hr>

You can also make a directly executable shellscript out of it using the so called shebang mechanism.

Put this line on the very top (line 1) of commands.sh


.. and make the file executable:

chmod +x commands.sh

Now you can execute it directly:

./commands.sh <hr>

If you want to say "yes" to all questions, you can use the yes command:

yes | bash "file_with_commands.sh"


No need to do something convolutied and as insane as trying to make cmd.exe work. You already got a perfectly fine working shell on your system. Also you need to understand what programs like sudo do.

sudo is not some magic chant that enables something. sudo is a helper program that allows to start a program with elevated rights. Instead of having a chain of sudo this sudo that you can as just let sudo start a shell and pass a script with all those commands to the shell.


sudo apt-get update sudo install xrdp sudo install java


sudo sh -c 'apt-get update ; install xrdp ; install java'

However that doesn't look right. I think you originally meant to write

sudo apt-get update sudo apt-get install xrdp sudo apt-get install java

You can shorten this to

sudo apt-get update sudo apt-get install xrdp java

Or in coalesced single liner shell

sudo sh -c 'apt-get update ; apt-get install xrdp java'

Now regarding the Yes/No questions. If a program you want to run unattended doesn't offer an option to give a default answer you can make use of the yes program. Even it being named yes it can also answer NO or anything you like:

narfi /home/dw 1007 ~ % yes Hello Hello Hello Hello Hello Hello …

How does this work? There's a concept called the "Standard Input / Output" from which programs read input from and write output to. Shells allow you to redirect the output from one program into the input of another one. This is called pipe-ing. The special character | designates a pipe in shells.

So say you've got a program that wants to see a large number of Aye inputs you could make the following call to the shell

yes Aye | happypirate

So you can combine this with apt-get to give all default yes answer writing

yes | apt-get install …

However this is barking up the wrong tree. Have a look at the call options for apt-get:

~ % apt-get --help apt for amd64 compiled on Oct 16 2012 18:23:06 Usage: apt-get [options] command apt-get [options] install|remove pkg1 [pkg2 ...] apt-get [options] source pkg1 [pkg2 ...] apt-get is a simple command line interface for downloading and installing packages. The most frequently used commands are update and install. … -y Assume Yes to all queries and do not prompt <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< …

apt-get gives you an option to auto-answer all yes to all it questions. Neat, right? Note that other programs may use different option keys so you're well advised to always read their fine manuals (RTFM).


At its most basic level, you want to eecute a script. You do that by creating a file like this:

#!/bin/bash sudo apt-get update sudo install xrdp sudo install java

Save that as a file called go, then in the Terminal, you need to make it executable like this:

chmod +x go

Then you can run it by typing:


If your program expects an answer of "yes" for the first question, then "no" for the next question, you can prepare the answers in advance like this and send them into the program:

( echo yes; echo no ) | sudo apt-get update
