Useful and cool Linux and Vim tricks

#linux #vim #terminal

Hi folks,

I recently joined the community call on the Discord server of the Growin Community. We had a Linux session where we learned some handy tricks with Linux.

If you don’t own a Linux machine, don’t worry! You can use:

Killer Koda — Just choose Ubuntu from here.
copy.sh

Alright, you're all set to get your hands on the terminal.

3, 2, 1, Go! 🔫🚀

LINUX Tricks

To execute a previous command:
- history — prints the history of commands.
- !<cmd_no> — executes a command from history based on its number.
To copy and paste lines in vim:
- Esc + 10yy — copies 10 lines.
- Paste with p to insert after the cursor.
To perform a reverse search:
- Ctrl+R — reverse search through the command history.
To count lines in a file:
- wc -l aks.txt — counts and lists the number of lines.
Yanking (copying) in vim:
- yy — yanks (copies) the current line.
- Esc + 5yy — yanks (copies) 5 lines.
- Paste with p after yanking.
Navigating in vim:
- Esc + :1 — jumps to line 1.
- :set nu — enables line numbers.
- Esc + Shift+G — moves to the end of the document.
Deleting in vim:
- Esc + dG — deletes everything from the current line to the end of the document.
- Esc + u — undoes the last change.
Finding unique adjacent lines in a file:
- uniq -c — looks for unique adjacent lines.
Sorting, unique filtering, and counting occurrences:
- cat aks.txt | sort | uniq -c — lists all unique lines in aks.txt with their counts after sorting.
