Restating what is written above:
"has a nonzero exit status"

Read about it here:
http://mywiki.wooledge.org/BashGuide/TestsAndConditionals#Exit_Status

Demo:
$ f=0; (( f == 1 )); echo $?
1
$ f=1; (( f == 1 )); echo $?
0

The exit status.  Do people always ensure exit status is correct?

When `f` is not `1`, I just print some help.
