gsub is for finding and replacing a pattern in a string. eLunate explains gsub very well here. Just use string.sub().
You can read more about string manipulation here.
An example script would follow as so:
local String = "Hello, World!"
local newString = string.sub(String,1,5)
print(newString)
--// OUTPUT
Hello
