The script is launched by the server, not manually.
I modified the script so I can run it manually, and it turns out that
"if line == nil" doesn't break from the while loop:
============
# cat test.lua
#!/usr/bin/lua
--Must first empty stdin
while true do
local line = io.read()
-- BAD if line == nil then break end
if line == "" then break end
-- Without line below, script never ends
-- io.write("NOOP ",line,"\n")
end
print("Hello")
============
# ./test.lua
test
test
Hello
#
============
If it works fine when ran manually, I can't find why the script
doesn't proceed when called from the server :-/
Thank you.
