(X)Ubuntu post install script

mainstream · 09-20-2014, 07:42 AM

Hi all,

I created a small post installation (bash) script for Xubuntu, since i grey tired of repeating this steps all the time.

It's adding ppa's
Installs some apps
Adds some system tweaks
Adds fonts
Etc.network-manager-openvpn

Is there someway i can test/simulate the script without altering any files and see all the output?

Best regards

Set up an installation in a virtual machine and run your script in it. Best way to see if it works all the way through.

Another way would be to use a copy of the script and have it write changes to test files and in place of actual installs just send an echo to terminal or to a file so you can see the steps occuring without actually downloading or installing. If that worked well you could do the VM idea I mentioned first for a full dress rehearsal run, as it were.

There's no easier way?
I remember adding a command to the bash script that would simulate the script, but i can't seem to remember it. Something like set -vx

I have this in my script. It does, however, not install all the apps?

EDIT: i found it. I skipped installing programs because tlp and skype are not in the repository. Is there any way to install the other program when a program is not in the repository?

you can install each program with its own apt-get command.
you could also tell your script to add the repositories to install skype.

but by now you should begin to realise that all this is not so simple and running it in a vm is maybe not such a bad idea.

Indeed thanks

but it's more a fallback when a app is not available, it continues with the rest.
I only need something to report it when it's not installed - any tips?

Output is E: Unable to locate package $app

You mean running in a loop?

Code:

INSTALL="skype tlp vlc xbmc openvpn etc"
for app in $INSTALL
do
	echo "Processing $app"
	sudo apt-get -y install $app
done

yes.
i guess i'd just put the apt-get commands there one by one, but yours is more flexible and easier to change.

Thanks, but how can i check the output from the loop?
So i can see which app didn't install?

if you run the script from a terminal, it will show the output, just like running the command manually.
