Here are five essential commands that a Linux administrator should know:
| Command | Description |
|---|---|
ls |
Lists files and directories in the current directory. Use ls -l for detailed information. |
cd |
Changes the current directory. Example: cd /path/to/directory to navigate to a specific path. |
cp |
Copies files or directories. Example: cp source.txt destination.txt to copy a file. |
rm |
Removes files or directories. Use with caution, as rm does not move files to a trash bin. |
sudo |
Executes commands with superuser (root) privileges. Example: sudo apt update to update packages. |
These commands form the foundation for navigating and managing a Linux system effectively.
