Command-Line – How to Write a Shell Script to Install a List of Applications

aptcommand linescripts

Does anyone know how to write a shell script to install a list of applications? It's a pain to have to install each application by hand every time I set up a new system.

Edit:
It still asks me Do you want to continue [Y/n]?. Is there a way to have the script input y or for it not to prompt for input?

Best Answer

I would assume the script would look something like this:

#!/bin/sh
apt-get update  # To get the latest package lists
apt-get install <package name> -y
#etc.

Just save that as something like install_my_apps.sh, change the file's properties to make it executable, and run it from the command line as root.

(Edit: The -y tells apt-get not to prompt you and just get on with installing)

Ubuntu – How to set system-wide proxy address using shell script

Try this:

#! /bin/sh
echo "# Generated by Application"
export http_proxy='http://$1/'
export ftp_proxy='http://$1/'

Note:

your argument string($1) should be like this

user_id:pass@proxy.server.addr:proxy_port

If you do not use userid and password then argument string($1) should be

proxy.server.addr:proxy_port

you can export https_proxy and socks_proxy if you need.
To see if your proxy is set or not use env | grep proxy

To change system proxy using shell script try these:

gsettings set org.gnome.system.proxy mode 'manual'
gsettings set org.gnome.system.proxy.http enabled true
gsettings set org.gnome.system.proxy.http host 'proxy.server.addr'
gsettings set org.gnome.system.proxy.http port proxy_port

If you have user authentication pass and id

gsettings set org.gnome.system.proxy.http authentication-user 'user_id'
gsettings set org.gnome.system.proxy.http authentication-password 'password'

To use http_proxy for all other proxy

gsettings set org.gnome.system.proxy use-same-proxy true

To set bypass proxy for any host

gsettings set org.gnome.system.proxy ignore-hosts "['localhost',  '127.0.0.1', 'all', 'other', 'hosts']"
