Shell command
=============
command
-------
Main semantic is to invoke command instead defined function with same name::
$ ls() { ls --color "$@"; }
$ ls # infinitely loop as func invoke itself
$ ls() { command ls --color "$@"; }
$ ls . # invoke /bin/ls with color output
$ unset ls # forget func definition
$ ls # invoke /bin/ls without color output
With '-p' arg Perform the command search using a default value for PATH that
is guaranteed to find all of the standard utilities::
$ command -p getconf PATH
With '-v' arg work like 'which' command which not included in POSIX::
$ command -v ls
/usr/bin/ls
$ command -v echo # for build-in command print command itself
echo # you can check for equality or for slash to
# distinguish from utilities
