NAME
command - execute a simple command
SYNOPSIS
command command_name [ argument ... ]
DESCRIPTION
command 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 command is the same as omitting command .
OPERANDS
command recognizes the following operands:
command_name | The name of a |
argument | One or more strings to be interpreted as arguments to command_name. |
The command 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 command is intended to imply that the command line is parsed any differently than any other simple command. For example,
command a b ; c
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 INFLUENCE
Environment Variables
PATH determines the search path used during the command search.
RETURN VALUE
command exits with one of the following values:
∙If command fails:
126The utility speci®ed by the command_name is found but not executable.
127An error occurred in the command utility or the utility speci®ed by command_name is not found.
∙If command does not fail:
The exit status of command is the same as that of the simple command speci®ed by the arguments:
command_name[ argument ... ]
EXAMPLES
Create a version of the cd command that always prints the name of the new working directory whenever it is used:
cd() {
command "$@" >/dev/null pwd
}
Circumvent the rede®ned cd command above, and change directories without printing the name of the new working directory:
command cd
