Linux Mint commands are not only for maintaining servers without GUIs. They are useful to personal computer users as well because they enable you to get things done faster in some cases. This is a continuously updated list of Linux Mint commands that provides examples of how to use the commands so that you can hit the ground running. Linux Mint is Ubuntu-based, therefore many of these commands will also work on Debian, Ubuntu and other Debian-based distributions.

Disclaimer: Please note that you are solely responsible for what happens if you execute any of the Linux Mint commands herein, and that commands can do very different things dependent on the version of Linux Mint you are using, under which account the commands are executed among other reasons. Please exercise caution and do additional research if you are unsure about anything. Read Kompulsa’s disclaimer.

Note: ‘sudo’ is only required if you are not at a root shell.

Install Software, Uninstall, And Search For it

The following Linux Mint command installs an app on Linux Mint via command line without the GUI. This example installs ‘htop’, a system resource monitor.

sudo apt install htop

Note: It is best to run ‘sudo apt update’ first.

The above method installs software using the Aptitude package manager [PDF] on Linux Mint. You can also use ‘dpkg’ to install software from a ‘.deb’ package you downloaded from outside the official Linux Mint repositories. For example: 

sudo dpkg -i appname.deb

What to do if you don’t know the exact name of the package? Let’s use ‘apt-cache search’ for that. See the following example in which we search for the Firefox development package.

sudo apt-cache search firefox dev

The output from the command shows the packages that most likely match that name:

firefox-dev - Safe and easy web browser from Mozilla - development files
libmozjs-91-dev - SpiderMonkey JavaScript library - development headers
cbindgen - Generates C bindings from Rust code
gnome-shell-extension-gsconnect-browsers - Browser support of KDE Connect implementation for GNOME Shell
html2wml - converts HTML pages to WML (WAP) or i-mode pages
libfirefox-marionette-perl - module to automate the Firefox browser with the Marionette protocol

There it is at the top! Now we can just install it by typing ‘sudo apt install firefox-dev’.

Uninstall A Package In Linux Mint Via Command Line

If you need to uninstall an app via command line on Linux Mint, use the command in the following example which removes ‘htop’. Note that this command does not cleanly remove all the files associated with an app. 

sudo apt remove htop

If you need to remove a package cleanly, including its data and configuration, add ‘–purge’ to the command. Note that the ‘purge’ command is more aggressive in its attempts to remove associated files. Please be careful which symbols you use with this command, as it could yield unexpected results.

sudo apt remove --purge htop

Upgrade all packages on your system, except those that weren’t installed via the repositories

sudo apt upgrade

Editing Files Via Command Line In Linux Mint

There are many Linux Mint commands you can use to edit files. However, the one that is most likely to work (even if you have a fresh installation of the OS and haven’t gotten the chance to install anything yet) is Nano. Type ‘nano [filename]’. You can also use ‘vi’.

nano filename.txt

Viewing Files Via Command Line In Linux Mint

One of the most common Linux Mint commands to view files is ‘less’. See the example of the ‘less’ command’s usage below to open the file ‘filename.txt’:

less filename.txt

You can also use ‘tail -f filename’ to view the end of a file. This is useful if you want to see the latest events in a large log file.

Locating Files In Linux Mint

You can find a file in Linux Mint that you need to edit or view using the ‘locate’ command as shown below. This is useful if you’re told to edit a certain configuration file but the person doesn’t tell you where it is on your machine. Note that you may need to run ‘sudo updatedb’ for it to work beforehand. Here’s an example of the ‘locate’ command’s usage:

locate pg_hba.conf

That command locates the ‘pg_hba.conf’ configuration file used by PostgreSQL and tells you which directory it is in.

Authentication: Log In To A User Account On Linux Mint And Log Out

You can log into an account using the command line on Linux Mint by typing the ‘login’ command as shown in the following Linux authentication [PDF] example.

sudo login

It will prompt you with ‘[computername] login:‘ at which point you would enter the username you want to login as. Press enter when done and then enter the password.

To log out, type the following to return to the previous account you were logged in as:


Create a user account via command line

sudo adduser new_user_name

Remove a user account

sudo deluser username

Change your password


View the groups your username is in on Linux Mint


You can view the groups a different user is in as shown below

groups username

Open the sudoers file

If you need to open the sudoers file in order to add a username or alter sudo privileges, you can use the following command:


List files, their owners and permissions

ls -l

Format ‘cd [directoryname]’.

cd mystuff

You can get around this by typing ‘rm -rf’ instead.

rm -rf mystuff
