20 Essential Linux Terminal Tricks to Boost Your Productivity

1. Use Tab for Auto‑completion

Press the Tab key while typing a command to automatically suggest completions that start with the characters you have entered, saving keystrokes and reducing errors.

2. Switch Back to the Previous Directory

cd -

The cd - command returns you to the last working directory without re‑typing the full path.

3. Return to the Home Directory

cd ~

or simply cd, which is pre‑configured in most modern shells and saves a few keystrokes.

4. List Directory Contents Quickly

ll

On many Linux distributions, ll is an alias for ls -l, providing a detailed listing with less typing.

5. Run Multiple Commands on One Line

command_1; command_2; command_3

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

6. Run the Next Command Only If the Previous Succeeds

command_1 && command_2

Use && so the second command runs only when the first exits successfully (e.g., sudo apt update && sudo apt upgrade).

7. Search Your Command History

ctrl + r

Press Ctrl + R and type a keyword to perform a reverse search through your Bash history; press Ctrl + C to exit.

8. Unfreeze a Stuck Terminal (Ctrl + S)

In many Unix‑like systems, Ctrl + S pauses output; press Ctrl + Q to resume.

9. Jump to Line Start or End

Ctrl + A   # move to start of line
Ctrl + E   # move to end of line

These shortcuts are especially handy on laptops where Home/End keys may be less accessible.

10. Follow Log Files in Real Time

tail -F linuxidc_log

The -F option follows the file by name and retries if the file is recreated.

11. Read Compressed Logs Without Decompressing

zcat linuxidc_log.zip | more

Use zcat, zless, or zgrep to view gzipped logs directly.

12. Use less to Browse Files

less -N linuxidc.txt

less

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

13. Reuse the Last Argument of the Previous Command

!$

After creating a directory, you can quickly change into it with cd !$. An alternative is Alt + .

14. Repeat the Previous Command with !!

!!

Useful for re‑executing a command with sudo, e.g., sudo !!.

15. Create Aliases to Fix Typos

alias gerp=grep

Define an alias in .bashrc to correct frequent misspellings.

16. Copy and Paste in the Terminal

Select text and right‑click to paste (common in PuTTY).

Select text and middle‑click to paste.

Use Ctrl + Shift + C to copy and Ctrl + Shift + V to paste.

17. Terminate a Running Command

Press Ctrl + C to stop the current process.

18. Empty a File Without Deleting It

> filename

This truncates the file to zero length.

19. Find Files Containing Specific Text

grep -Pri "search_string" path

Search recursively, ignoring case, and display matching file names.

20. Use Help for Any Command

$bc -help

Most commands provide a built‑in help page that explains usage and options.
