Search Linux commands + examples.. Linux Commands Ref is a free online tool from the ToolsRift Developer Tools collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Search for a command or task to find the right Linux utility, its common flags and a ready example you can adapt for files, processes, text or networking.
grep searches inside file contents for matching text, while find locates files and directories by name, type, size or other attributes.
ps aux lists all processes, and top or htop show them live with CPU and memory usage that updates in real time.
chmod sets read/write/execute bits (e.g. chmod 755 file) and chown changes the owner and group of a file or directory.
