How do you write a log from the ash (bash) that can be viewed in the logread? Ive tried using the logger command, but it doesnt work.

logger "Log message"

Example from my wifi wps button:

root@OpenWrt:~# cat /etc/rc.button/wps
#!/bin/sh

if [ "$ACTION" = "pressed" -a "$BUTTON" = "wps" ]; then
        logger "WPS button pressed, looking for active radios"
        echo "255" > /sys/devices/platform/leds-gpio/leds/netgear:green:wps/brightness
        for dir in /var/run/hostapd*; do
                [ -d "$dir" ] || continue
                logger "WPS activated for: $dir"
                hostapd_cli -p "$dir" wps_pbc
        done
        sleep 10
        echo "0" > /sys/devices/platform/leds-gpio/leds/netgear:green:wps/brightness
fi

root@OpenWrt:~# logread | tail -n 5

Mon Apr 14 19:29:22 2014 user.notice root: WPS activated for: /var/run/hostapd

And you can also set the visible source for the user.notice class:

root@OpenWrt:~# logger -t "source" message line

root@OpenWrt:~# logread | tail -n 2
Mon Apr 14 19:29:22 2014 user.notice root: WPS activated for: /var/run/hostapd
Mon Apr 14 19:32:32 2014 user.notice source: message line

A bit around, but you can try

ubus call log write '{ "event": "Foo" }'

;) What's wrong with "logger" for you?

Yeah, my syntax was wrong, i was writing 'logger message' instead of 'logger "message"'

Thanks for your help!
