this guy securitys!!! also block port 22 on your firewall so nobody can access SSH.

I guess I’ll post it here then:

#!/bin/bash

# Function to display the menu
display_menu() {
  echo "Select an option:"
  echo "1. Move all .LRV files to 'LRV' directory"
  echo "2. Undo move operation"
  echo "3. Rename files starting with 'GL' to 'GX'"
  echo "4. Undo renaming operation for .LRV files"
  echo "5. Exit"
  read -p "Enter choice (1, 2, 3, 4, or 5): " choice
}

# Function to handle option 1
move_lrv_files() {
  # Create the LRV directory
  mkdir "LRV"

  # Move all the .LRV files to the LRV directory
  mv *.LRV "LRV"
  echo "Moved all .LRV files to 'LRV' directory"
}

# Function to handle option 2
undo_move_operation() {
  # Move all .LRV files back to the working directory
  mv LRV/*.LRV .

  # Remove the LRV directory
  rmdir LRV
  echo "Undid move operation"
}

# Function to handle option 3
rename_files() {
  # Rename files starting with 'GL' to 'GX'
  for file in GL*; do
    newname="${file/GL/GX}"
    mv "$file" "$newname"
    echo "Renamed file '$file' to '$newname'"
  done
}

# Function to handle option 4
undo_rename_files() {
  # Undo renaming operation for .LRV files (revert files from 'GX' to 'GL')
  for file in GX*.LRV; do
    newname="${file/GX/GL}"
    mv "$file" "$newname"
    echo "Renamed file '$file' to '$newname'"
  done
}

  # Use directory provided as command-line argument
  directory=$2
else

fi

# Change the working directory and check if it was successful

  while true; do
    display_menu

    case $choice in

  done
else

  echo "Error: Invalid path. Please double check the working directory."
fi

wow, what a crazy way to see it, but at the end of the day it’s true.

No sir, you’re doing it wrong. This is being done without security in mind. That way, just anyone can execute anything.

chmod 666 -R / is the way.

Edit: remember to run as root
