post	Custom cmds in Ubuntu	Create custom commands in Ubuntu (and other Linux distros).	sthope	bash-logo.png	Ubuntu Linux	Ubuntu 20.04	true

⚠️⚠️⚠️ This was done using {{page.distro_tested}} but it should work on most Linux distros the same way.

Create Folders

On the terminal create folder to save your customs scripts eg:

mkdir -p ~/bin

Create Scripts

Inside the new folder created create a new file,eg: `nano ~/bin/y2upgrade`

Edit the Scripts

Edit the file with your commands and save, eg:

#!/bin/bash

sudo apt-get update
sudo apt-get upgrade -y

Set Access Permissions

Use chmod to set files permissions. (should ask twice for sudo password)

sudo chmod +x ~/bin/*;su -l $USER

Testing

Now you should be able to send your command from the terminal, the file name is the command name for example now when entering: `y2upgrade` it should first do `sudo apt-get update` and then `sudo apt-get upgrade -y`.

`-y` simply means it will not ask you Y/n if you want to accept installing the upgrades in case there is any.

Extra

SSH without asking for password.
Create file named `sshnopwd` and paste the [contents of this file](https://git.sthope.dev/sthope/sthope_website_examples/raw/branch/master/custom-cmds-in-ubuntu/bin_examples/sshnopwd)

now instead of using ssh username@ip and then entering password, simply run sshnopwd password username@ip and it will automatically login.
