Don't know about a shell way to do this, but what about this tiny
C program (compile and link with gcc -c -o r.o && gcc -or r.o)
#include <stdlib.h>
#include <time.h>
=20
int main (int argc, char *argv[]) {
srandomdev();
/* use this on non-BSD systems:
srandom(time (0));
*/
=09
unsigned int r =3D random () % 99999 +1;
printf ("%d\n", r);
=09
return r;
}
Cheers,
Simon
