I tried such code to redirect standart output to the file:
subprocess.Popen('my command', cwd='my path', shell=True, stdout=stdout.txt, stderr=stdout.txt)
But got error: NameError: name 'stdout' is not defined
I use python version 2.5.2
Open the file first and use a
to append if you want to keep a record of all output/errors or use w
to overwrite each time:
with open("stdout.txt","a+") as stdout:
subprocess.Popen('my command', cwd='my path', shell=True, stdout=stdout, stderr=stdout)
Using with
will automatically close your file.
将文件描述符提供给stdout 请参阅doc
