This isn't a BSD question. It's just about elementary C. As other people pointed out, you could have easily caught it anyway just by turning on warnings.

can anybody clue me in why the followin joinline program fails to catch if argc 
== 1?

* simple prog to join all | very nearly all lines of a text file that * make up one paragraph into one LONG line. *
 * paragraphs are delimiated by a single \n break.

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

main(int argc, char argv[])
   char buf[65536];

   if (argc == 1)
        printf("Usage: %s < file > newfile\n", argv[0]);
        exit (-1);
   while (fgets(buf, sizeof buf, stdin) )
     if (*buf == '\n')
       fprintf(stdout, "\n\n");
       buf[strlen(buf)-1] = ' ';
       fputs(buf, stdout);
