When I look at some scripts I see %s in the script or something with the % at the beginning of it.

When googling it didn't turn much up.

What is the %s used for?

I'm guessing you saw it in a sprintf() statement or something similar. sprintf is a way to format what you want to print.

The %s is a placeholder in the string being printed and a variable is given at the end of the sprintf statement that will get placed where that placeholder is located.

There are different kinds of % arguments you can use and they're listed in the link to the function above. %s is for a string.

The link to the sprintf function will explain it all better than I am and there are a few other similar functions.

yea i found about sprintf function. that is what i was looking for

Glad I could point you in the right direction.
