Snowflake log is not written


I followed this guide to run my own snowflake: Tor Project | Standalone Snowflake proxy. It seems that everything is working out.
By the following command I try to see the log file: cat /home/pi/snowflake/proxy/snowflake.log, but there’s an error stating:

pi@raspberrypi:~/snowflake/proxy $ cat /home/pi/snowflake/proxy/snowflake.log

nohup: ignoring input

nohup: failed to run command ‘./proxy’: No such file or directory

Any help here?
