Re: [Jython-users] Problem with command module

[Kevin M. <qk...@lm...>]

The solution is a bit more complicated it seems. The following works well.


from java.io import *
from java.lang import *

proc = Runtime.getRuntime().exec("ls -la")
stdin = proc.getInputStream()
isr = InputStreamReader(stdin)
br=BufferedReader(isr)

line = br.readLine()
while line != None :
        print(line)
        line = br.readLine()


I got some help from this resource:

Comments?
