Coding Standards
Here are few things I came up with :
Please suggest any changes that you feel necessary :

1. Header
Each Shell script file will use this Header template at the top of the file.

#######################< Shell Script>###############
# Owner:
# Application:
#
# Date: DD-MON-YYYY
# File Name:
# Author:
# @(#) Description:
# Parms:
# Called By:
# Output:
#
# Modification History:
#
# Change Date Name Description
# ----------------------------------------------
#
##################################################

2. Commenting

1. Lines can be commented with a # (hash)

2. Make comments distinguishable from the code.

3. Make sure comments and the code match.

4. Never comment out a portion of the code without a comment describing why, who and when. If the need for the commented out code has expired, remove the commented out portion.

5. Comments should be indented to the level of the code they describe.

3. Modification Log
Whenever a code is modified make sure that there is a modification log.

A modification log is one which has the details of what has been modified, by whom and when. Include this detail along with the header.

4. Naming

1. All the constants and environment variable names should be in Capital letters.
2. All script variables must be lower case.
3. All the variable names should be meaningful.
4. All the function names should be related with the functionality of the code.
5. Don't name the variable in single character (such as i,j,a), it will be tough to search the single character for code changes.
6. Don't keep the keywords as variable or function names.

repertoiremap

REPERTOIREMAP(5)						 Linux User Manual						  REPERTOIREMAP(5)

NAME

       repertoiremap - map symbolic character names to Unicode code points

DESCRIPTION

       A  repertoire  map  defines  mappings  between  symbolic  character  names (mnemonics) and Unicode code points when compiling a locale with
       localedef(1).  Using a repertoire map is optional, it is needed only when symbolic names are used instead of  now  preferred  Unicode  code
       points.

   Syntax
       The repertoiremap file starts with a header that may consist of the following keywords:

       comment_char
	      is followed by a character that will be used as the comment character for the rest of the file.  It defaults to the number sign (#).

       escape_char
	      is  followed  by	a character that should be used as the escape character for the rest of the file to mark characters that should be
	      interpreted in a special way.  It defaults to the backslash ().

       The mapping section starts with the keyword CHARIDS in the first column.

       The mapping lines have the following form:

       <symbolic-name> <code-point> comment
	      This defines exactly one mapping, comment being optional.

       The mapping section ends with the string END CHARIDS.

FILES

       /usr/share/i18n/repertoiremaps
	      Usual default repertoire map path.

CONFORMING TO

       POSIX.2.

NOTES

       Repertoire maps are deprecated in favor of Unicode code points.

EXAMPLE

       A mnemonic for the Euro sign can be defined as follows:

       <Eu> <U20AC> EURO SIGN
