A Linux command cheat sheet offers quick reference to essential commands:

- File Navigation: `ls` (list files), `cd` (change directory), `pwd` (print working directory).

- File Operations: `cp` (copy files), `mv` (move/rename files), `rm` (remove files), `touch` (create file), `mkdir` (create directory).

- File Viewing: `cat` (view file content), `less` (view large files), `head`/`tail` (view start/end of files).

- Permissions: `chmod` (change permissions), `chown` (change ownership).

- System Info: `df` (disk usage), `top` (processes), `uname` (system info).

- Networking: `ping`, `ifconfig` (network interface).

These commands are fundamental for everyday Linux use.
