Introduction to the Terminal¶

Familiarity with and mastery of the command-line terminal is important for developers at all skill levels.

You can run the shell commands in this notebook, but we recommend that you open a terminal and type the shell commands directly.

Start a New Terminal¶

In the notebook file tree, look for the buttons on the upper right and click New > Terminal.

Though it has a steep learning curve, we strongly recommend learning a powerful editor called Vim.

In [ ]:

# Start the vim editor
# vim

Each Linux distribution has its own package manager. Fedora uses the dnf package manager.

In [ ]:

# Install the git package
# sudo dnf -y install git

You can suspend, resume and stop processes that are taking too long.

In [ ]:

# Suspend current process
# Press CTRL-Z

In [ ]:

# Resume process in background
# bg

In [ ]:

# Resume process in foreground
# fg

In [ ]:

# Stop current process
# Press CTRL-C

If you are using the terminal (and not running commands in this notebook), you can take advantage of time-saving keyboard shortcuts.

We often find that people teach each other and learn cool tricks when working together in the same terminal.
