Cau,

a) V Debian distribuci mame realpath (Je v balicku dwww.):
hekale:~$ realpath /usr/X11/bin/xview
/usr/X11R6/bin/xloadimage
hekale:~$ dpkg -S realpath
dwww: /usr/bin/realpath
dwww: /usr/man/man1/realpath.1.gz
manpages-dev: /usr/man/man3/realpath.3.gz

b) Shell script: resolve
#!/bin/bash
# Pozor!!! NEFUNGUJE PRO JMENA SOUBORU OBSAHUJICI MEZERY!!!

#include <stdio.h>
#include <sys/param.h>
#include <unistd.h>

int main(int argc, char *argv[])
{
        char resolved[MAXPATHLEN];
        if (argc > 1) {
                printf("%s\n", realpath(argv[1], resolved));
                return 0;
        }
        else {
                fprintf(stderr, "Use: %s filename", argv[0]);
                return 1;
        }
