What are the differences between 'bash' and 'sh'
Hopefully this doesn't come off as too much of a "newbie" question or a flamebait. But I have recently begun working with a Sun Solaris box after having spent the past five years working with RedHat. From what i can tell, thing look fairly similar and the 'man' command is some help. But I've noticed that the default shell is 'sh' and I tend to be more familiar with 'bash' since that's the default in RedHat. I understand that the reason that 'sh' is the defatul for root is that it's statically compiled and available even if the /usr partition is unavailable. But there are features that I like that seem to be missing:
-Arrow up for command history
-Arrays or creating arrays like this: test1=( `ls` )
-Emacs style editing on the command line
Just to name a few. So my question is, how different is 'sh' from 'bash'. I imagine there are things I will have to rewrite in my bash scripts to get them to work under 'sh'. But how much work am I really in for? Are there any good resources online that will lay out the differences or good books that anyone would recommend? I love the O'Reilly book on Bash. Anything similar for 'sh'? Thanks

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
