BASH - Check that it is not running the same script

Question

I have a script /root/data/myscript

and when I run /root/data/myscript

I do not know how to determine if you have one running

does anyone know?

I tried

if [[ "$(pidof -x /root/data/myscript | wc -w)" > "1" ]]
then echo "This script is already running!"
fi

thank you

Thank. It is not for me right solution. Control must be from that file /root/data/myscript — Z55

Do you want a generic solution or something that can work for myscript? — anubhava

This should work.

if [[ "$(pgrep myscript)" ]]
then echo "This script is already running!"
fi

It is wrong :-( Condition will be satisfied Whenever. Controls the startup of the same file...

This could work to check whether the script is already running or not.

if [[ "$(ps -ef | grep "/root/data/myscript" | grep -v "grep")" ]] ; then 
echo "This script is already running!"
fi

Try this one.
