How to log on Linux?

Postby mrunix » 19 Jun 2012, 04:39


I use POCO library. I encounter a strange problem. my system is Linux for embedded PowerPC.

If I login to system first, I start my app like this:

# app &

I can got the log "app.log".

If I start my app like this:

# app --daemon

I can run the app, but cann't get any log, didn't create 'app.log' file.

QUESTION1: If I run my app by command line, how can I get the log?

If I start my app by "/etc/inittab", like this:


I start my app in rcS script file. I can run my app, but the app cann't create "app.log" file.

QUESTION2: If I run my app by "/etc/inittab", how can I get the log?

Thank you!
