because i can fit it into a toot, a mini version of seq(1) Afficher plus

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

#define NULLCHK(S) if ((S) != NULL)\
exit(1)

/*
* A basic implementation of seq(1). Supports neither floating-point bounds nor
* custom increment values.
*/
int
main(int argc, char **argv) {
if (argc < 2 || argc > 3)
exit(2);

long long lo, hi;
const char *errstr = NULL;

lo = (argc == 2) ? 1 : strtonum(argv[1], LLONG_MIN, LLONG_MAX, &errstr);
NULLCHK(errstr);

hi = strtonum(argv[argc - 1], LLONG_MIN, LLONG_MAX, &errstr);
NULLCHK(errstr);

for (long long i = lo; i <= hi; i++)
printf("%lld\n", i);

exit(0);
}

tech gripe, gnu Afficher plus

@KitRedgrave because gnu utils tend to be horrifyingly overcomplicated as well as being originally written to avoid accusations of copying then-proprietary unix sources

compare the man pages:
http://man.cat-v.org/unix_8th/1/seq
https://linux.die.net/man/1/seq

i decided to make the whole thing infinitely more simple by dropping floating-point entirely, because i'll only be using it as a for-loop replacement thing in ksh scripts

@KitRedgrave venture into the sources if you dare:
https://git.savannah.gnu.org/cgit/coreutils.git/tree/src/seq.c

even more horrifying, the implementation of yes(1) which prints out either y or a single string indefinitely
https://git.savannah.gnu.org/cgit/coreutils.git/tree/src/yes.c

i don't have any other implementations to look at right now, but i'd imagine it's not doing buffer allocation to print strings fast

@KitRedgrave for comparison, busybox yes(1), which actually resembles something real human beings would write:
https://git.busybox.net/busybox/tree/coreutils/yes.c

but yes, the whole factor of not wanting to get sued by whoever got bells labs when bell was broken up was a factor in the gnu style
