These seemed so easy, I couldn't wait.

Here's a quick tee.c source for capturing it's stdin, logging it to a
file and writing it to stdout.  I haven't tried it with my st, but
it works on my HP 360 HP-UX machine.

#include <stdio.h>

#define MAXLINE 500

main(argc, argv)
int argc; char *argv[];
{
	FILE *fp;
	char *str[MAXLINE];

	if ( argc == 1 ) {
		printf("tee: must specify log file.\n");
		exit(1);
	} else 	if (argc == 2) {
		if ( (fp = fopen(argv[1], "w")) == NULL ) {
			printf("tee: cannot open %s for writing.\n", argv[1]);
			exit(1);
		}
	} else if (argc == 3) {
		if ( (fp = fopen(argv[2], "a")) == NULL ) {
			printf("tee: cannot open %s for writing.\n", argv[2]);
			exit(1);
		}
	}
	
	while ( fgets(str, MAXLINE, stdin) != NULL ) {
		printf("%s", str);
		fputs(str, fp);
	}
	exit(0);
}
