Code:

your script

else
echo "Script is Already Running with Another User,Please try after some time"


it will work
Yes, it will work but is not optimal. The better approach is the use of a pidfile as others have suggested.

Save a process be not using grep -v grep. do it like this instead:
Code:
p_count=`ps -ef | grep [p]rocess.sh | wc -l`

This matches the text "process.sh" but not itself (the string "[p]rocess.sh").
