Lua accessing table stored in external file - lua

Question

I have an external lua file that has a table stored in it that is formatted as follows:
sgeT = {
2535047 = {
{
["account"] = "TG-MCB110105",
["exec"] = "/share/home/00288/tg455591/NAMD_2.8b3/NAMD_2.8b3_Linux-x86_64-MVAPICH-Intel-Ranger/namd2",
["execEpoch"] = 1305825864,
["execModify"] = "Thu May 19 12:24:24 2011",
["execType"] = "user:binary",
["jobID"] = "2535047",
["numCores"] = "128",
["numNodes"] = "8",
pkgT = {
},
["runTime"] = "65125",
["sha1"] = "e157dd510a7be4d775d6ceb271373ea24e7f9559",
sizeT = {
["bss"] = "104552",
["data"] = "192168",
["text"] = "10650813",
},
["startEpoch"] = "1335843433",
["startTime"] = "Mon Apr 30 22:37:13 2012",
["user"] = "guo",
},
},
2535094 = {
{
["account"] = "TG-MCB110105",
["exec"] = "/share/home/00288/tg455591/NAMD_2.8b3/NAMD_2.8b3_Linux-x86_64-MVAPICH-Intel-Ranger/namd2",
["execEpoch"] = 1305825864,
["execModify"] = "Thu May 19 12:24:24 2011",
["execType"] = "user:binary",
["jobID"] = "2535094",
["numCores"] = "128",
["numNodes"] = "8",
pkgT = {
},
["runTime"] = "81635",
["sha1"] = "e157dd510a7be4d775d6ceb271373ea24e7f9559",
sizeT = {
["bss"] = "104552",
["data"] = "192168",
["text"] = "10650813",
},
["startEpoch"] = "1335823028",
["startTime"] = "Mon Apr 30 16:57:08 2012",
["user"] = "guo",
},
}
I want to iterate through the table like an array and return the exec key, value pair, and I am completely new to lua and I am using the following script:
FileStr = "lariatData-sgeT-2012-05-31.lua"
Hnd, ErrStd = io.open(FileStr, "r")
myTable = loadTable(FileStr)
if Hnd then
for Str in Hnd:lines() do
print(Str, "\n")
for exec, val in pairs(myTable) do
print(exec.." "..val, "\n")
end
end
Hnd.close()
else
print(ErrStr, "\n")
end
However, it is returning that the table is nil. What am I doing wrong?

In continuation of comments above:
-- Notice that I've used `[2535047]`
sgeT = {
[2535047] = {
{
["account"] = "TG-MCB110105",
["exec"] = "/share/home/00288/tg455591/NAMD_2.8b3/NAMD_2.8b3_Linux-x86_64-MVAPICH-Intel-Ranger/namd2",
["execEpoch"] = 1305825864,
["execModify"] = "Thu May 19 12:24:24 2011",
["execType"] = "user:binary",
["jobID"] = "2535047",
["numCores"] = "128",
["numNodes"] = "8",
pkgT = {
},
["runTime"] = "65125",
["sha1"] = "e157dd510a7be4d775d6ceb271373ea24e7f9559",
sizeT = {
["bss"] = "104552",
["data"] = "192168",
["text"] = "10650813",
},
["startEpoch"] = "1335843433",
["startTime"] = "Mon Apr 30 22:37:13 2012",
["user"] = "guo",
},
},
}
The above is your file. Then, your Lua program shall be:
FileStr = "lariatData-sgeT-2012-05-31.lua"
Hnd, ErrStr = io.open(FileStr, "r")
if Hnd then
dofile(FileStr)
for Str in Hnd:lines() do
print(Str, "\n")
for exec, val in pairs(sgeT) do
print(exec.." "..val, "\n")
end
end
Hnd.close()
else
print(ErrStr, "\n")
end
