Having problem with executing shell script to get the pid details!

Hello Everyone,
I am new to shell scripting and also i am very new to AIX machine
I have a question.
I have shell script which contains the follwing

"ps -e |grep $1
echo $2"

i run this schell script by doing this ./startSehllscript 3444 passed with two parameters .
Accroiding my assumption i though it will print the pid details with the parameter 2.
but when i run this script it could return me back kust a single string "passed"

I wanted to get the process deatils.
If i run this "ps -e |grep $1" in the UNIX shell it runs fine and gives me back the pid details but when i do it by the shell script it deos not return me back the pid details.
How can we write the commadn ina such a way that it will return me back the pid details.

I would really appreciate if some one can answer my question.

What exactly you are trying to do? your question doesnt have any goal/scenario.

ps -e |grep $1

This will grep $1 from ps -e output....

If you are trying to find the output as PID and the corresponding process then try following....

ps -e|awk '{print $1 " " $4}'

Rephrasing my question...

Sorry for the inconvenience...I am rephrasing my question.

My main goal is to execute a shell script which will take "pid" as a parameter and the shell script should print the details of the "pid".
For this purpose i have created a shell script with the following content..
"ps -e |grep $1
echo $2"

When i execute the script with the parameter pid with some other parameter it does not print the pid .......

Hope it is bit clear to you....

are you looking for a script like below?

echo " Enter the PID: "
read a
ps -ef |grep $a

A script to display details on the process given as first argument + it's children:
ps -fT $1
