Useful and cool Linux and Vim tricks

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:

1. Killer Koda — Just choose Ubuntu from here.
2. 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.
