Hello friends

I want to write a script in which I will connect to my friends network.
I want to use SSH.
Even they can use the script to log into my network and copy files.

ssh user@hostname command

I know the following command will help me to log into Google's servers and see all the people who are logged into their system.
ssh Angelo@www.google.com who


I guess the following program will help to copy the files.
…................................................................................................... .................................................................................................... .....

Code:

* #!/bin/sh

** $ cat mycp
*#

*# copy a file

*#

* if [ "$#" -ne 2 ]
* then

*** echo "Usage: mycp from to"
*** exit 1
* fi

* from="$1"

* to="$2"


*#
*# See if the destination file exists
*#

*if [ -e "$to" ]
*then
*** echo "$to already exists; overwrite (yes/no)?"
******* read answer


****** if [ "$answer" !=yes ]
****** then
********* echo "Copy not performed"
********* exit 0
****** fi
*fi


*#
*# Either destination doesn't exist or "yes" was typed
*#

* cp $from $to**** # proceed with the copy

* $

I need your help to write a script to this end.
I can log into their networks and copy files and exit.
I want to use SSH to log into the networks.
Your help is deeply appreciated.
