command
command [-pVv] command [arguments …]
Runs command with arguments ignoring any shell function named command. Only
shell builtin commands or commands found by searching the PATH are executed. If
there is a shell function named ls, running ‘command ls’ within the function
will execute the external command ls instead of calling the function
recursively. The -p option means to use a default value for PATH that is
guaranteed to find all of the standard utilities. The return status in this
case is 127 if command cannot be found or an error occurred, and the exit
status of command otherwise.
If either the -V or -v option is supplied, a description of command is
printed. The -v option causes a single word indicating the command or file name
used to invoke command to be displayed; the -V option produces a more verbose
description. In this case, the return status is zero if command is found, and
non-zero if not.
$ command --help
command: command [-pVv] command [arg ...]
Execute a simple command or display information about commands.
Runs COMMAND with ARGS suppressing shell function lookup, or display
information about the specified COMMANDs. Can be used to invoke commands
on disk when a function with the same name exists.
Options:
-p use a default value for PATH that is guaranteed to find all of
the standard utilities
-v print a description of COMMAND similar to the `type' builtin
-V print a more verbose description of each COMMAND
Exit Status:
Returns exit status of COMMAND, or failure if COMMAND is not found.
"If there is a shell function named ls, running ‘command ls’ within the
function will execute the external command ls instead of calling the function
recursively."
Is this the main point to command? "will execute the external command ls
instead of calling the function recursively"
What is the difference between 'execute' and 'calling' ?
Maybe "execute' does not return any exit value from the program being executed?
