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.
In the notebook file tree, look for the buttons on the upper right and click New > Terminal.
List files in this folder.
List files with more information.
Show help for the ls command.
Reveal current folder.
Change to root folder.
Autocomplete folder names.
# Type cd /home/u and press TAB
Save text to a file.
ls > /tmp/files.txt
Append text to a file.
ls >> /tmp/files.txt
Show command history.
Save command history to a file.
history > /tmp/history.txt
Though it has a steep learning curve, we strongly recommend learning a powerful editor called Vim.
# Start the vim editor # vim
Each Linux distribution has its own package manager. Fedora uses the
dnf package manager.
# Install the git package # sudo dnf -y install git
You can suspend, resume and stop processes that are taking too long.
# Suspend current process # Press CTRL-Z
# Resume process in background # bg
# Resume process in foreground # fg
# 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.
