linux tee is not working with python?
From man python
:
-u Force stdin, stdout and stderr to be totally unbuffered. On systems where it matters, also put stdin, stdout and stderr in binary mode. Note that there is internal buffering in xreadlines(), readlines() and file- object iterators ("for line in sys.stdin") which is not influenced by this option. To work around this, you will want to use "sys.stdin.read‐ line()" inside a "while 1:" loop.
So what you can do is:
/usr/bin/python -u client.py >> logfile 2>&1
Or using tee
:
python -u client.py | tee logfile
Instead of making it fully unbuffered you can make it linebuffered as it is normally with sys.stdout.reconfigure(line_buffering=True)
(after import sys
of course).
This was added in 3.7, docs: https://docs.python.org/3/library/io.html#io.TextIOWrapper.reconfigure
