Custom key combination doesn't work

  • 772

I'm trying to control the volume of a nearby music player by sending a command to the server. That is easy enough: 

echo "[mac address] mixer volume -10" | nc server 9090

works perfectly from the command line and decreases the volume by 10 points. Likewise, +10 increases the volume. Now I want to assign these commands to key combinations Ctrl + F7 and Ctrl + F8, respectively. I open up the System Settings/Keyboard panel and enter two custom key combinations. However, these don't work: nothing happens when I press the keys.

I tried adding full paths to echo (/bin/echo) and nc (/bin/nc); then I tried redirecting the SYSOUT and SYSERR of the nc command to some log file, but nothing shows up (but then, nc is not supposed to output anything). Finally, I put the string [mac address] mixer volume -10 in a file called .softer and set the key combination to

/bin/nc server 9090 < /home/jos/.softer

Likewise with .louder. Still, nothing happens.

What am I doing wrong? Again, all versions of these commands do work and change the volume if issued from the command line.

    A possible answer (I usually use it) is to create .sh file containing this command then assign a bash /path/to/sh-file command using shortcuts this should solve your problem.
