How to evaluate process command without substituting environment variables?

[jshah]

I have a command (below), and I don't want to have supervisor try to substitute asctime, levelname and message with env vars.

command=/usr/local/bin/rq worker default --log-level '%(asctime)s - %(levelname)s - %(message)s'

Is there a way I can have supervisor just run the command as is without trying to substitute env vars?

Error when running

Error: Format string '"/usr/local/bin/rq worker default --log-level \'%(asctime)s - %(levelname)s - %(message)s\'"' for 'program:rq-worker.command' contains names ('asctime') which cannot be expanded.

Escape the % with a %.

$ cat supervisord.conf
[supervisord]
loglevel = debug

[program:dumpargs]
command = python3 dumpargs.py worker default --log-level '%%(asctime)s - %%(levelname)s - %%(message)s'
startsecs = 0
autorestart = false

$ cat dumpargs.py 
import sys
print(sys.argv)

$ supervisord --version
4.2.4

$ supervisord -n -c supervisord.conf
