command in Mac OS X

By: Strauss K  

Run command with args suppressing the normal shell function lookup.

Syntax
      command [-pVv] command [arg...]

Key
    -p   Use a default value for PATH that will find all the standard utilities.

    -v   Print a description of command

    -V   Print a verbose description of command

Only builtin commands or commands found in the PATH are executed.

Exit Status
If the -V or -v option is supplied, the exit status is 0 if command was found, and 1 if not. 
If neither option is supplied and an error occurred or command cannot be found, the exit status is 127. 
Otherwise, the exit status of the command builtin is the exit status of command.

Example

$ command ls

command is a builtin command
