20 Essential Linux Terminal Tricks to Supercharge Your Productivity

Here are some useful Linux commands, terminal tricks, and shortcuts that can save a lot of time when using the Linux command line.

1. Use Tab for Auto‑completion

Press the Tab key while typing a command to automatically complete file names or commands that start with the typed prefix.

Tab can also be used to complete commands after they are partially typed.

2. Switch Back to the Previous Directory

Use cd - to return to the last working directory without re‑typing the full path.

cd -

If no previous directory exists, an error like bash: cd: OLDPWD not set will be shown.

3. Return to the Home Directory

Use cd ~ or simply cd to jump to the home directory from anywhere.

cd ~

cd

4. List Directory Contents Quickly

Instead of ls -l, many users prefer the ll alias, which provides a detailed listing.

ll

5. Run Multiple Commands on One Line

Separate commands with a semicolon ; to execute them sequentially without waiting for each to finish.

command_1; command_2; command_3

6. Run Commands Conditionally (Only on Success)

Use the double‑ampersand && to run the next command only if the previous one succeeds. command_1 && command_2 Example:

sudo apt update && sudo apt upgrade

7. Search Your Command History

Press Ctrl + r and type a keyword to perform a reverse search through previously entered commands.

ctrl + r keyword

8. Unfreeze a Frozen Terminal

On many Unix‑like systems, Ctrl + S pauses output. Resume with Ctrl + Q.

9. Jump to Line Start or End

Use Ctrl + A to move to the beginning of the line and Ctrl + E to move to the end.

10. Follow Log Files in Real Time

Use tail -F <logfile> to continuously monitor a log file, even if it is rotated or recreated.

tail -F linuxidc_log

11. Read Compressed Logs Without Decompressing

Use the z suite (e.g., zcat, zless, zgrep) to view gzip‑compressed files directly.

zcat linuxidc_log.zip | more

12. Use less to View Files

less -N <file>

provides paging, searching, line numbers, and does not load the entire file into memory.

less -N linuxidc.txt

13. Reuse the Last Argument of the Previous Command

Type !$ to insert the final argument from the preceding command.

14. Re‑execute the Entire Previous Command

Use !! to repeat the last command, useful for quickly adding sudo.

15. Create Aliases to Fix Typos

Define an alias such as alias gerp=grep to correct common misspellings.

alias gerp=grep

16. Copy and Paste in the Terminal

Typical shortcuts: select text and right‑click to paste (PuTTY, Windows SSH clients), or use Ctrl + Shift + C / Ctrl + Shift + V for copy/paste in many terminals.

17. Terminate a Running Command

Press Ctrl + C to stop the currently executing command or process.

18. Empty a File Without Deleting It

> filename

19. Find Files Containing Specific Text

grep -Pri "search_string" /path/to/search

For more advanced file searching, see the find command documentation.

20. Use the Built‑in Help for Any Command

Most commands provide a help page (e.g., bc -help) that describes usage and options. bc -help These Linux terminal tricks work on almost all distributions and shells without installing additional tools.
