function split(str, pat)

local t = {} -- NOTE: use {n = 0} in Lua-5.0

local fpat = "(.-)" .. pat

local lastend = 1

local s, e, cap = str:find(fpat, 1)

while s do

if s ~= 1 or cap ~= "" then

table.insert(t,cap)

end

lastend = e+1

s, e, cap = str:find(fpat, lastend)

end

if lastend <= #str then

cap = str:sub(lastend)

table.insert(t, cap)

end

return t

end

I found that script on exploitdb's papers , already downloaded the files.csv and modified the path but i still cant run that script. If someone can help me with that i would appreciate.

Thank you
