Linux Terminal Guide: Managing Files and Directories
1. Creating Files and Directories
– Create a File:

– Command: `touch filename.txt`

– Example: `touch example.txt` creates an empty file named `example.txt`.
– Create a Directory:

– Command: `mkdir directoryname`

– Example: `mkdir myfolder` creates a directory named `myfolder`.
2. Moving Files and Directories
– Move a File:

– Command: `mv sourcefile destination`

– Example: `mv example.txt /home/user/documents/` moves `example.txt` to the `documents` folder.
– Rename a File or Directory:

– Command: `mv oldname newname`

– Example: `mv example.txt newname.txt` renames `example.txt` to `newname.txt`.
3. Deleting Files and Directories
– Delete a File:

– Command: `rm filename`

– Example: `rm example.txt` deletes `example.txt`.
– Delete a Directory:

– Command: `rm -r directoryname`

– Example: `rm -r myfolder` deletes the `myfolder` directory and its contents.
Best Practices
– Use `-i` for Safety: Add `-i` to `rm` or `mv` commands to prompt before deleting (e.g., `rm -i file.txt`).

– Check Before Deleting: Use `ls` to list files before running `rm` to avoid accidental deletions.

– Backup Important Data: Always back up files before performing bulk operations.
Troubleshooting Tips

– Permission Denied? Use `sudo` before commands if you lack permissions (e.g., `sudo rm file.txt`).

– Accidental Deletion? Check backups or use file recovery tools like `testdisk`.
