On my reelbox (running Ubuntu) I have found a file in /etc/init that contains the following
# frontpanel-pre - check for frontpanel CAPs and adjust time # description "check frontpanel caps" #start on starting mountall #start on tty-device-added DEVNAME=/dev/ttyS0 task script ( /sbin/dev_frontpanel.sh /sbin/reelfpctl -capability ) > /dev/.frontpanel.caps initctl emit --no-wait frontpanel-linked end script
I wonder if the dot in /dev/.frontpanel has some special meaning in linux
I thought the output of the commands in the brackets will be written to a file called ".frontpanel.caps" in /dev/ but there is no such file. In /dev/ there is a frontpanel which is a link to /dev/ttyS0
Could it be, that e.g.
echo something > /dev/.frontpanel.caps actually sends data (something in this case) to /dev/frontpanel ?
.caps do then?
