 echo "1.displays PID of go login shell"

 echo "2. displays process status"

 echo "3. detail listing process"

 echo "4. display process of user"

 echo "5. display all user process"

 echo "6. display system process"

 printf "enter choice:"

 read choice

 if [ $choice==1 ]

 then

 echo " PID of curent shell is:$"

 fi

if [ $choice==2 ] 

 then

 ps

 fi

if [ $choice==3 ]

 then

 ps -f

 fi

if [ $choice==4 ]

 then

 printf "enter username"

 read user

 ps -u $user

  fi

if [ $choice==5 ]

 then

 ps -a

 fi

if [ $choice==6 ]

 then

 ps -e

fi
