Adam_G :
I am running a jar file from python using something to this
import subprocess
subprocess.call(['java', '-jar', 'tool.jar'])
I would then like to save the output to a file, but the issue is that the original java code has the output being sent to System.err.println(output). I would love to modify the original java file, but this is not an option.
How can I send this output to a file? I have tried:
subprocess.call(['java', '-jar', 'chattool.jar', '>', 'out.txt', '2','>','err.txt'])
as well as
subprocess.call(['java', '-jar', 'chattool.jar', '&>', 'test.txt'])
but neither one redirects the output. Is it possible to do this within python?
Maurice Meyer :
You can pipe stdout/stderr into a file using Popen():
_stdout = open('/tmp/chattool.stdout.txt', 'w')
_stderr = open('/tmp/chattool.stderr.txt', 'w')
cmd = subprocess.Popen('java -jar chattool.jar', stderr=_stderr, stdout=_stdout, cwd=_cwd, shell=True)
cmd.communicate()
