make directory script

Hi,

I try to write a script to create a new directory.

#!/bin/bash

echo "Please enter folder name (6 characters only) :"
read foldername
mkdir /home/user/$foldername
$foldername >> /home/list/list.txt


My question/situation:
1) how to ensure the folder name MUST BE 6 characters only? if user enter more than 6 character, need them to re-enter.
2) if new folder name already exist in /home/user/, how to notify user the folder name already exist and ask them to re-enter?
3) if foldername created, i append the foldername in list.txt . Like situation in (2), how to notify user if the folder name already exist?

mkdir - Makes directory

SYNOPSIS
bool mkdir (string $pathname, [int $mode = 0777], [bool $recursive = false], [resource $context]) DESCRIPTION
Attempts to create the directory specified by pathname. PARAMETERS
o $pathname - The directory path. o $mode - The mode is 0777 by default, which means the widest possible access. For more information on modes, read the details on the chmod(3) page. Note $mode is ignored on Windows. Note that you probably want to specify the mode as an octal number, which means it should have a leading zero. The mode is also modified by the current umask, which you can change using umask(3). o $recursive - Allows the creation of nested directories specified in the $pathname. o $context - Note Context support was added with PHP 5.0.0. For a description of contexts, refer to "Streams". RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 mkdir(3) example <?php mkdir("/path/to/my/dir", 0700); ?> Example #2 mkdir(3) using the $recursive parameter <?php // Desired folder structure $structure = './depth1/depth2/depth3/'; // To create the nested structure, the $recursive parameter // to mkdir() must be specified. if (!mkdir($structure, 0777, true)) { die('Failed to create folders...'); } // ... ?> ERRORS
/EXCEPTIONS Emits an E_WARNING level error if the directory already exists. Emits an E_WARNING level error if the relevant permissions prevent creating the directory. NOTES
Note When safe mode is enabled, PHP checks whether the directory in which the script is operating has the same UID (owner) as the script that is being executed. SEE ALSO
