For example:

A slightly more involved example:

# echo "((sig >= 10 && sig < 15) || sig == 17) && comm != bash" > filter
If there is an error in the expression, you'll get an 'Invalid
argument' error when setting it, and the erroneous string along with
an error message can be seen by looking at the filter e.g.:
-# cd /debug/tracing/events/sched/sched_signal_send
+# cd /sys/kernel/debug/tracing/events/signal/signal_generate
# echo "((sig >= 10 && sig < 15) || dsig == 17) && comm != bash" > filter
-bash: echo: write error: Invalid argument
