Shell Programming and Scripting

Hi all
I want to put this script on start-up the sh Terminal to save history of output:

Code:

if [ -z "$UNDER_SCRIPT" ]; then       
        logdir=$HOME/terminal-logs
        if [ ! -d $logdir ]; then
                mkdir $logdir
        fi
        gzip -q $logdir/*.log
        logfile=$logdir/$(date +%F_%T).$$.log
        export UNDER_SCRIPT=$logfile
        script -f -q $logfile
        exit
fi

But I can't find how to do that. I should only use the sh shell. yes in bash shell there is some way, but how about sh?
I alter the files profile .dtprofile and I create .profile on root directory and changed all of them and add this codes:

Code:

 echo Rahim
ls -a
Rahim=123
echo $Rahim

But any of them didn't work.
Is it possible to put Script on start-up the Terminal to execute every time that a Terminal starts? If possible please let me know.
I use x86 sun Solaris 10.

Thanks for your helps.

Q.1:
How do you connect?

If you connect via a Xserver ( emulator like Rx or Hummingbird...), and use ssh, do you know which profile is being used?... (Look at the man pages of ssh...)

Are you talking of local on a workstation ?

In any case the best is to put your code in a script and call the script in the good .profile using exec otherwise you will find yourself with the prompt waiting yet another exit since script forks a new shell...

Now it is on my virtual box and it is local. But on the office I connect Using Xserver.
Sometime we use telnet, But that's not so important. When we connect from Xserver to desktop of the Solaris I need to do that. I can't find the .profile file in home, then I create one but nothing! I think echo command maybe not worked.
then you said to me I should call my Script with the exec command on .profile?
OK let me try.
Thanks for your help.

There is an importance: using telnet you will read .profile, using ssh you will not unless you create a environment file in .ssh directory specifying so...
I tested at work your bit of script : put in a script and called the script in .profile... works as expected :
Even though you put an exit at the end and I added an extra as last line of .profile when I type exit I found myself at the prompt so:
You must use my previous syntax using exec
I tested... works great...

But not for me!
I am so new on this. I should try. but another question?
Where is the .profile location? I didn't have any! I create one in the / directory. Am I right?

It give me the error cannot execute
I exec it directly from Terminal with this

Code:

./Savelog

this was the second question! Am I right?

Is that literally what it said, and literally all it said?
