Shell Programming and Scripting

I am trying to write a script where I would login to a userid with id and password while staying completely within the script. I am doing this in order to edit a file where I change permissions. The objective is to allow one user only to edit a file. This is what I have now.


cd $HOME/data

if [[ -f firstrun_edit ]]
then
echo "File in use by "
cat infirstrun
echo "Try again later"
exit
fi
whoami > infirstrun this is where I would login
chmod 755 firstrun
cp firstrun firstrun_bkup
mv firstrun firstrun_edit
vi firstrun_edit
mv firstrun_edit firstrun
rm -f infirstrun
chmod 555 firstrun
exit


I am also interested in using the tso edit in a second script. Does anyone know if you can do a tso command that would put you in the file in edit the same way the vi filename does? If so what is the code? I know if I just put tso where I have the vi line I will end up in the main tso screen but I am interested in being in it the same as what vi puts you in the file to edit.

One way is to put a filter script which directs the user to the script in /etc/profile or whatever your default profile is when logging in.

We have something similar to this in my company, we have a group that monitors our boxes across the country, and they have a menu driven login access. When they login they get a menu of actions which they can use.
