This is drifting off topic, and I'm OK with the invocation I use now,
but that doesn't work:

$ head -1 ~/.todo.actions.d/datefilter.awk
#!/usr/bin/gawk --re-interval -f

$ chmod u+x ~/.todo.actions.d/datefilter.awk

$ ~/.todo.actions.d/datefilter.awk
Usage: gawk [POSIX or GNU style options] -f progfile [--] file ...
Usage: gawk [POSIX or GNU style options] [--] 'program' file ...
