11 Must‑Know Linux Terminal Tricks to Supercharge Your Workflow

1. Everyday Command‑Line Shortcuts

Boost efficiency with these key bindings: CTRL+U – delete text before the cursor CTRL+K – delete from cursor to end of line CTRL+Y – paste previously deleted text CTRL+E – move cursor to end of line CTRL+A – move cursor to start of line ALT+F – jump forward one word ALT+B – jump backward one word ALT+Backspace – delete the previous word CTRL+W – delete the word after the cursor Shift+Insert – paste into the terminal

Example of fixing a typo:

sudo apt-get install programname

2. sudo !! – Re‑run the Previous Command as Root

If a command fails with “Permission denied”, prepend it with sudo automatically using sudo !!: apt-get install ranger becomes

sudo apt-get install ranger

3. Pause a Foreground Job and Return to It Later

Press CTRL+Z to suspend the current job, then type fg to bring it back to the foreground. This is handy when editing a file with nano and you need to run another command without exiting the editor.

4. Keep Commands Running After Logout with nohup

When connected via SSH, prepend a long‑running command with nohup and suffix it with & to detach it from the session:

nohup wget http://mirror.is.co.za/mirrors/linuxmint.com/iso/stable/17.1/linuxmint-17.1-cinnamon-64bit.iso &

5. Schedule One‑Time Commands Using at

Use the at utility to run a command at a specific future time. Example:

at 10:38 PM Fri
cowsay 'hello'
CTRL+D

This schedules cowsay 'hello' for Friday at 22:38.

6. Enhance man Pages

Set a colorful pager: export PAGER=most (install most first).

Adjust line width: export MANWIDTH=80.

Open man pages in a browser: man -H (requires the BROWSER environment variable).

7. Interactive Process Management with htop

Install htop and run it to view and manage processes in a UI similar to Windows Task Manager. Use function keys to change sorting, and press F9 to kill a selected process.

8. Browse the Filesystem with ranger

After installing ranger, launch it with the same command. It presents a three‑pane, column‑based view where left/right arrows navigate directories.

9. Cancel an Ongoing Shutdown

Use shutdown -c to cancel a pending shutdown (may fail if shutdown has already started). An alternative is to kill the shutdown process:

pkill shutdown

10. Quickly Kill Hung Processes

Find processes with ps -ef or htop.

Use xkill to click‑and‑kill a graphical window.

Force a hard reboot without the power button using the magic SysRq sequence REISUB (hold Alt+SysRq and press R, E, I, S, U, B in order).

11. Download YouTube Videos with youtube-dl

Install youtube-dl from your package manager and download a video with: youtube-dl url-to-video Copy the video URL from the YouTube share link and paste it (e.g., with Shift+Insert).
