I'm having trouble controlling
fbi through a named pipe, it seems fbi simply stops listening to the pipe after the first write and I can't figure out why.
I'm running something like:
$ mkfifo /tmp/fbi $ sudo fbi -T 1 *.png < /tmp/fbi &  19374 $ echo -n "." > /tmp/fbi using "DejaVu Sans Mono-16", pixelsize=16.67 file=/usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf
After this it looks like something starts listening to STDIN (line becomes black with no cursor showing but I can type in whatever) but after pressing enter I simply get:
+ Done fbi -T 1 *.png < /tmp/fbi
fbi keeps on running normally after this, but it won't listen to the fifo anymore. If I try to write something into the fifo after this I get stuck there until I CTRL-C out of it, which is the same that happens when writing to a fifo which has nothing listening to it.
Things to keep in mind:
- I'm using a RPI 3 with Raspbian Jessie Lite
- I'm running this from SSH
- fbi version 2.09, compiled on Oct 21 2014
- If I run fbi manually it won't listen to STDIN for commands either, it simply puts me back on bash and continues to run with whatever arguments I launched it
Things I have tried:
- Using nohup to launch fbi
- Writing to process via
echo "something" > /proc/[fbi pid]/fd/0
- Using both root and normal user pi
- Writing these commands to .bashrc so it runs on autologin without having to ssh into the raspberry
None of the previous worked for me. What could I be doing wrong? Thanks for reading.
