This is a series highlighting best-of-breed utilities. We cover a wide range of utilities including tools that boost your productivity, help you manage your workflow, and lots more besides. There’s a complete list of the tools in this series at the end of each page.
The Command Line Interface (CLI) is a way of interacting with your computer. To harness all the power of Linux, it’s highly recommended mastering the interface. It’s true the CLI is often perceived as a barrier for users migrating to Linux, particularly if they’re grown up using GUI software exclusively. While Linux rarely forces anyone to use the CLI, some tasks are better suited to this method of interaction, offering inducements like superior scripting opportunities, remote access, and being far more frugal with a computer’s resources.
The part of the operating system responsible for managing files and directories is called the file system. It organizes our data into files, which hold information, and directories (also called ‘folders’), which hold files or other directories. Several commands are frequently used to create, inspect, rename, and delete files and directories.
One of these commands is ls, which prints the names of the files and directories in the current directory. A directory is really just a file. It’s a special file with special rules. The ls utility appeared in the first version of AT&T UNIX.
Are you looking to liven up your shell? Want a bit more beauty on your terminal? lsd is an enhancement for the venerable ls command. It’s written in Go.
There’s quite a few methods to install the software on our Ubuntu systems. We can use Rust’s package manager cargo, use the developer’s official Ubuntu package, install with a snap, or even install a precompiled binary.
We chose the first method. On a vanilla Ubuntu 21.04 installation, cargo isn’t installed by default. Rectify that with the command:
$ sudo apt install cargo
Next we installed lsd using cargo.
$ cargo install lsd
We also need to install the patched fonts of powerline nerd-font and/or font-awesome. There are instructions on the project’s GitHub page.
One further step is that you’ll need to ensure ~/.cargo/bin is in your PATH. The variable $PATH is set by your shell every time it launches, but you can set it so that it always includes your new path with every new shell you open. The exact way to do this depends on which shell you’re running.
For the bash shell we follow these steps:
- Open the .bashrc file in our home directory (
~/.bashrc) in a text editor.
export PATH=”~/.cargo/bin:$PATH”to the last line of the file.
- Save the .bashrc file.
- Restart my terminal (or run the command
