people, i've been under the weather for days and will probably be for a few more.
new and TEMPORARY meds dont like me, ugh.
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");
}
else
{
buf[strlen(buf)-1] = ' ';
fputs(buf, stdout);
}
}
}
