Need a script to create file permission change restriction

Hello,

I am looking for a UNIX shell script which can help me for access restriction.

1) /home/ram, there are number file with .txt extension, which should be only owned "ram" user.
like as below

Code:

ls -lrt *.txt
-rwx------ 1 ram dba 11 Jan  4  2015 PASS1.txt
-rwx------ 1 ram dba 10 Jan  4  2015 PASS2.txt
-rwx------ 1 ram dba 10 May 10  2015 PASS3.txt
-rwx------ 1 ram dba 13 Jan 10 03:37 PASS4.txt

2) In case ram user, fortunately/unfortunately make any permission change, immediately email group should get alert.

3) Immediately file permission for .txt extension file again should come on same file permission like (-rwx------), it means ram user will only have "rwx" no one else.

Let me explain you by example

Code:

ls -lrt *.txt
-rwx------ 1 ram dba 11 Jan  4  2015 PASS1.txt
-rwx------ 1 ram dba 10 Jan  4  2015 PASS2.txt
-rwx------ 1 ram dba 10 May 10  2015 PASS3.txt
-rwx------ 1 ram dba 13 Jan 10 03:37 PASS4.txt

If you see as of now ram user only having 'rwx', now unfortunately ram execute chmod 777 *.txt, then all *.txt will have 777 permission,
If any .txt file change permission command (apart from Ram --> "rwx") execute on particular directory
then immediately email group should get alert, as well as file permission should get change with only "-rwx------"

Please advice script.

Regards,

chsh

CHSH(1)                                                            User Commands                                                           CHSH(1)

NAME

       chsh - change login shell

SYNOPSIS

       chsh [options] [LOGIN]

DESCRIPTION

       The chsh command changes the user login shell. This determines the name of the user's initial login command. A normal user may only change
       the login shell for her own account; the superuser may change the login shell for any account.

OPTIONS

       The options which apply to the chsh command are:

       -h, --help
           Display help message and exit.

       -R, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory.

       -s, --shell SHELL
           The name of the user's new login shell. Setting this field to blank causes the system to select the default login shell.

       If the -s option is not selected, chsh operates in an interactive fashion, prompting the user with the current login shell. Enter the new
       value to change the shell, or leave the line blank to use the current one. The current shell is displayed between a pair of [ ] marks.

NOTE

       The only restriction placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the superuser,
       and then any value may be added. An account with a restricted login shell may not change her login shell. For this reason, placing /bin/rsh
       in /etc/shells is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell
       back to its original value.

FILES

       /etc/passwd
           User account information.

       /etc/shells
           List of valid login shells.

       /etc/login.defs
           Shadow password suite configuration.
