That guy has a moose above his hostname. I thought the only way to add anything was manipulating PS1, but that moose is above his hostname?
Anyone know how to add something similar like that, maybe archs logo?

Answer 1

Ok, figured it out. Each of the "[..." actually needs to be prefixed with an (non-printable) ESCAPE character, ASCII code #27.
Since they're non-printable they cannot be displayed in this forum. :-p
I just wrote a little tool that writes a code-27 char in front of every "[" and that works.
//File 'issue-make.c'
//Create a usable 'issue' file (place it at /etc/issue) from various weirdly formatted text files.
//It accepts [... or [[... or ^[... escape sequences.
//By Jindur for bbs.archlinux.org. (Use/modify/hack/distribute/as you wish, just don't sell it.. as if lol).
//Maybe you don't want single [ to be recognized as ESC sequence. Delete the code lines then i guess.
#include <stdio.h>
int main(int argc, char *argv[])
char buf[256], buf2[256];
int n, n2;
FILE *f, *f2;
int just_converted = 0;
if (argc < 2)
printf("This tool converts escape sequences ^[.. [[.. and [.. into real escape sequences.\n");
printf("Enter filename of an ascii art file you wish to convert into a usable 'issue' file.\n");
printf("This will overwrite an existing 'issue' file in the current directory.\n");
printf("Example: issue-make my-cool-art.txt\n");
return 1;
f = fopen(argv[1], "r");
if (!f)
printf("Error: Could not open input file for reading.\n");
return 2;
f2 = fopen("issue", "w");
if (!f2)
printf("Error: Could not open 'issue' file for writing.\n");
return 3;
while (fgets(buf, 256, f))
n = -1;
n2 = -1;
do {
n++;
n2++;
//case 1: sequence ^[...
if (buf[n] == '^' && buf[n + 1] == '[')
n++;
buf2[n2] = 27;
just_converted = -1;
//case 2/3: sequence [ or [[
else if (buf[n] == '[' && !just_converted)
if (buf[n + 1] == '[')
buf2[n2] = 27;
just_converted = -1;
else
buf2[n2] = 27;
n2++;
buf2[n2] = '[';
just_converted = -1;
else
buf2[n2] = buf[n];
just_converted = 0;
} while (buf[n]);
fprintf(f2, "%s", buf2);
fclose (f2);
fclose (f);
return 0;
Use 'gcc' to compile.
