-- ** EXAMPLES TO RUN EXTERNAL APPLICATIONS ** --
-- run a command in a shell and wait for it to complete.
--
-- Details: basically just system(3), except on Unix like systems with
-- memory-locking, this call is special-cased to use vfork and close
-- file-descriptors. On other systems it defaults to Lua's os-library
-- built-in os.execute system() call.
os.execute ("date > /tmp/testdate")
-- os.forkexec() works as fire-and-forget. execv(3) style
--
-- Details: It calls vfork() and exec() under the hood, passing each
-- argument separately to exec (and needs a full-path to the binary).
os.forkexec ("/usr/bin/xterm")
os.forkexec ("/bin/sh", "-c", "import --frame \"/tmp/scr_$(date).png\"")
end end
