Thank you. That was exactly what I needed!
I did re-write the first function to not depend on your stuff (in case
anyone else wants it).
#!/usr/bin/env lua
local posix = require('posix')
local data = string.rep("a",72) .. "\n"
for i = 1 , 5 do
local my_time = posix.time()
io.stdout:write(my_time .. data)
io.stdout:flush()
posix.sleep(1) -- delay 1 second
end
Thanks again,
Dan
