members is a program that sends a space-separated list of secondary member names to its standard output.
Options

-

Show only primary group members.
-
-s, --secondary -

-
-t, --two-lines -
Send two lines to standard output. First line is primary members, second line is secondary members. NOTE: This always displays two lines, even if there are no members at all.

Diagnostics
Exit status is 0 (i.e. "success") if the group was found, and 1 (i.e., "failure") if the group was not found.
Technically, the exit status hinges on the output of getgrnam(3) as follows: if getgrnam(3) returns a null pointer, the exit status is 1, and 0 otherwise.
