Hi. I just made a code that worked fine on windows... but once i use it on linux it will read but not write anything....
Any help?

[LUA]
function MakePerpLogsForPlayers()
if not file.IsDir ("perp_logs", "DATA") then
file.CreateDir ("perp_logs", "DATA")
print ("perp_logs folder not found, Making one for the server.")
end
end
hook.Add ("Initialize", "MakeLogFolderForPlayerStart", MakeFolderForPlayer)

function MakePerpLogsForPlayersFolder(ply,ent)
local player = ply:SteamID()
local playerremade = ( string.Replace( player, ":", "" ) )
if not file.IsDir ("perp_logs/"..playerremade, "DATA") then
file.CreateDir ("perp_logs/"..playerremade, "DATA")
print ("perp_logs folder not found, Making one for the client on server.")
end
end
hook.Add ("PlayerInitialSpawn", "MakeLogFolderForPlayerTester", MakePerpLogsForPlayersFolder)

function HeDiedAndIWantAlogofIt(victim, inflictor, attacker)
local player = victim:SteamID()
local playerremade = ( string.Replace( player, ":", "" ) )
local userDataFile = "perp_logs/"..playerremade.."/playerdeath.txt"
if (file.Read(userDataFile) == nil) then file.Write(userDataFile,victim:Nick().." was killed by "..inflictor:Nick()) print ("couldn't find D:") return end
if inflictor:IsWorld() then
file.Append(userDataFile,"\r\n"..victim:Nick().."("..victim:SteamID()..") was killed by the world and the water level was "..victim:WaterLevel())
end
if !inflictor:IsWorld() then
file.Append(userDataFile,"\r\n"..victim:Nick().."("..victim:SteamID()..") was killed by "..attacker:Nick().."("..attacker:SteamID()..") by the 'weapon' "..inflictor:GetClass().." and the water level was "..victim:WaterLevel())
end
end
hook.Add("PlayerDeath","MakeLogsOFtHePLayerDeahtOk",HeDiedAndIWantAlogofIt)
