The $()-macro in gMFSK does not provide shell-style redirections,
command pipelines or sub-shells. You can basically only do simple
"command arg1 arg2 arg3..." (the actual work is done with glib
g_spawn_command_line_sync() function).

The get the result you want, you need to write an executable
shell script that does the above. Something like:

 #!/bin/sh
 echo "599000 +" $(cat /home/daniel/.xlog/test.xlog | wc -l) | bc

Put that somewhere, make it executable and then call it from gMFSK.
