使用例
[takuan@localhost ~]$ command -V ls
ls is aliased to `ls --color=auto'
[takuan@localhost ~]$ command -V cd
cd is a shell builtin
[takuan@localhost ~]$ command -v ls
alias ls='ls --color=auto'
command [-pVv] command [arg ...]
Run command with args suppressing the normal shell function lookup.
Only builtin commands or commands found in the PATH are executed.
If the -p option is given, the search for command is performed
using a default value for PATH that is guaranteed to find all of
the standard utilities. 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.
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 sta-
tus of command.
