command - execute a simple command SYNOPSIS
command_name [argument ...] DESCRIPTION
enables the shell to treat the arguments as a simple command, suppressing the shell function lookup. If command_name is not the name of the function, the effect of is the same as omitting command. Operands recognizes the following operands: command_name The name of a HP-UX command or a shell built-in command. argument One or more strings to be interpreted as arguments to command_name. The command is necessary to allow functions that have the same name as a command to call the command (instead of a recursive call to the function). Nothing in the description of is intended to imply that the command line is parsed any differently than any other simple command. For example, is not parsed in any special way that causes or to be treated other than a pipe operator or semicolon or that prevents function lookup on b or c. EXTERNAL INFLUENCES
Environment Variables determines the search path used during the command search. RETURN VALUE
