In computing, start is a command of the IBM OS/2,^[1] Microsoft Windows^[2] and ReactOS^[3] command-line interpreter cmd.exe^[4] (and some versions of COMMAND.COM) to start programs or batch files or to open files or directories using the default program. start is not available as a standalone program. The underlying Win32 API is ShellExecute.

The command is also one of the basic commands implemented in the Keyboard Monitor (KMON) of the DEC RT-11 operating system.^[5] The TOPS-10^[6] and TOPS-20^[7] operating systems also provide a start command. It is used to start a program in memory at a specified address.

• Typical Unix shells (bash, etc.) have no built-in registry of file types and associated default applications. Linux command-line tools with similar functions include xdg-open^[8] and run-mailcap.
• On Cygwin, the command is implemented as the cygstart executable.^[9]
• In PowerShell, the Invoke-Item cmdlet is used to invoke an executable or open a file.^[10]
• On Apple macOS and MorphOS, the corresponding command is open.^[11]
