I don’t understand your question. Do you mean when you use the command dmesg in the Edison console you don’t get the output or are you looking for another log?
are you searching for journalctl (/var/log/syslog replacement) ?
and some programs log into /var/log/whatever
Or are you asking about programs you download from arduino IDE?
All of the stuff that goes to stdout goes to the file: /tmp/log.txt
All of the stuff that goes to stderr god to the file: /tmp.log_err.txt
Note: in tmp so gone if you reboot...
I am trying to run Avahi-daemon process but meet some problem.
And I want to read some log.But dmesg and logread don't have the messges I am looking for.
I have tried to see the /var/log/journalctl.But it couldn't read.
you dont see /var/log/journalctl journalctl is a command you have to execute...
