The Linux command line is fast once you know the tools. This cheat sheet gathers 70+ commands you reach for daily, grouped by task: working with files and directories, changing permissions and ownership, managing processes, inspecting the network, checking disk usage, creating and extracting archives, managing users, and processing text with tools like grep, sed and awk.
Each row shows a command and a short explanation. Click any command to copy it to your clipboard, then paste it into your terminal and fill in the paths. Use the search box to filter across every group at once — try "chmod", "grep" or "network". Everything runs locally in your browser.
