I see how "cd", "ls -l", "man", "chmod", "who", etc... may be considered external commands. However, say for example i'm using the ssh command to log in remotely from my macbook to another macbook. I'm told from system preferences/shared to enter the following from my command line.
ssh hostname@ipaddress
Will this be different among other shells or is this not considered an internal command?
What constitutes internal commands from external commands? Could you please provide an example of a command that differs between zsh and bash?
Thanks for the reply it was very helpful as a beginner in UNIX/LINUX.

command-not-found
COMMAND-NOT-FOUND(1) http://en.opensuse.org/Sco COMMAND-NOT-FOUND(1)
NAME
command-not-found - A command-not-found handler
SYNOPSIS
command-not-found {binary_name} {repository}
ARGUMENTS
The following arguments are required:
binary_name
The name of binary you are looking for.
repository
The name of repository for search. For most cases, use zypp
DESCRIPTION
command-not-found handler is designed to tell users which package contains a missing command.
The handler is integrated to bash(1) and zsh(1) shells and is not necessary to call it directly. Just type a name of the command in your
favourite shell and you'll get a result.
If you consider c-n-f handler useless, just add unset command_not_found_handle to your profile or remove the command-not-found package.
Handler doesn't call the command-not-found binary directly, it only prints info about it. If you want to invoke it automatically, just add
export COMMAND_NOT_FOUND_AUTO=1 to your bash profile.
EXAMPLE
: NORMAL USAGE
For example you want to try blender, because you have heard that is an amazing program. So just type blender in shell:
$ blender
You get the following output:
The program 'blender' can be found in the following package:
* blender [ path: /usr/bin/blender, repository: zypp (openSUSE 11.1-0) ]
Try installing with:
sudo zypper install blender
bash: blender: command not found
