Hello Luciano!
Try the following:
function execute(command)
local lines = {}
local file = io.popen(command)
for line in file:lines() do
table.insert(lines, line)
end
file:close()
return lines
end
This does not explain why your code does not what you want, but is
should work.
You can list the whole table with:
output = execute('ls')
for n,line in output do print(n,line) end
Maybe your ls does not output two lines..

Hello listers,
I am trying to load a table with lines from a shell output. However,
I am not able to understand what is wrong.
#!./usr/bin/env lua
function execute(command)
local lines = {}
local file = io.popen(command)
while true do
line = file:read('*l')
table.insert(lines, line)
if line == nil then break
end
file:close()
return lines
end
output = execute('ls')
print(output[2])
Each line of the table should contain a line from the output, but in
stead of it, I have a looping.
