waiting for a program run by popen3() to end

[Miki Tebeka]

Hello Rajarshi,

>         o,i,e = os.popen3('/usr/local/adapt/bin/descmng -g')
>         o.write('\n%s\n\n' % (redpick))
>         o.close()
>         time.sleep(1)
>         os.system('mv set5 gendes.in && rm set? outputdesc.txt')
If you're not reading the program output you can use os.system which
will wait for it to end.

On Unix like systems there is popen2.Popen3 (or Popen4)

from popen2 import Popen3

print "Running child"
p = Popen4("my_process arg1 arg2")
print "Waiting"
p.wait() # Will wait for process to end
print "And we got:"
print p.fromchild.read()

HTH.
