Oh man you made mistake accessing evn variable inside your script.
First when you set a variable at your prompt, like i did a=10, then the same won't be available inside the script you are running.
The prompt shell is a different process and the script you are running is a different process.
If you are planning to share it, you have it to make it as environment variable by using export.
Check the output i have posted, i was not able to access a inside test.sh, but in the prompt i am getting it
Hi,
Thanks, I will try this solution tomorrow & then revert to you.
Regards,
Sunil

xtell
XTELL(1) General Commands Manual XTELL(1)NAME
xtell - sends a message to another computer running xtelld
SYNOPSIS
xtell [-v] [user[:tty][@host[:port]]] [message]
write user [tty]
DESCRIPTION
How to use it: suppose you want to send a message to user gubas on computer trener.fsport.uniba.sk Just type:
prompt:~% xtell gubas@trener.fsport.uniba.sk Hi
To send multiple lines long message to user 7tokarova at computer pascal.fmph.uniba.sk, type
prompt:~% xtell 7tokarova@pascal.fmph.uniba.sk
Hi
How are you today
Please answer
^D
in this case, finish sending messages with EOF (CTRL D)
If you want to send message to user holik on local computer, you can do it either by typing:
prompt:~% xtell holik@localhost Hi
or simply:
prompt:~% xtell holik Hi
To send message to certain tty, append the tty to username, separated by colon:
prompt:~% xtell stanys:ttyp2@reaktor.ip.fmph.uniba.sk 'Sveikas Tomai'
will send message 'Sveikas Tomai' to user stanys on ttyp2 at computer reaktor.ip.fmph.uniba.sk
To specify other port than the default 4224, append the port to computer name, separated by colon:
prompt:~% xtell bosa@radon.dnp.fmph.uniba.sk:4000 'Ahoj'
assumes the xtell daemon runs at computer radon on port 4000, and sends the message 'Ahoj' to user bosa.
Option -v turns verbose mode on. Xtell will then display some messgaes about connecting, which is usefull especially when the connection is
slow.
Example:
prompt:~% xtell -v rybar@dmpc.dbp.fmph.uniba.sk
xtell invoked without parameters will ask user for username and host to send the message to.
If the user has created in his/her/its home directory the file .xtell-log, and the file is writable by nobody, all messages will be written
to this file as well as to the screen (handy when the screen is overwritten and you could not see the message).
xtell checks the environmental variable XTELLPROMPT. If it exists, it is used as prompt for messages.
Last notice: if you do not think zsh is the best shell, (besides doing a mistake) replace prompt:~% in above text with prompt:~$ or what-
ever :-)

What happens to .xtell-log when two messages arrive simultaneously? There is no locking implemented.
