If the syntax of spawnl is:
spawnl(mode, path, ...)
Why does everyone write it like:
os.spawnlp(os.P_WAIT, 'cp', 'cp', 'index.html', '/dev/null')
or:
os.spawnl(os.P_WAIT, "/var/www/db/smm/smm_train", "smm_train",
"SMMTrainInput.xml")
How is the first 'cp' a path to a file? why does the desired executable have to
be named again as the first parameter?
Marginally educated guessing:
1. "cp" is a shell command, so no path is required or possible.
2. The repetition of the executable name is so that argv[0] can
have the expected contents: the name of the executable.
