Here is a random ordering that i wrote when i had nothing to do at 2:30am(EST). It consists of a c program and a shell script. Here is the c program: ---------cut here------------- #include <stdio.h> #include <sys/types.h> #include <sys/time.h> #define rnd(l,h) ( (random() % (1+h-l)) + l) /*seed random# generator*/ void rndseed() { struct timeval tp; /* structure for time output defined in time.h */ struct timezone tzp; /* timezone...also defined in time.h */ gettimeofday(&tp,&tzp); srandom (tp.tv_sec * tp.tv_usec); } main() { char linebuff[2049]; rndseed(); while(gets(linebuff) != NULL) printf("%d@%s\n",rnd(50,1000),linebuff); } ---------cut here------------- # #Shell script for rsort program. #NOTE: change ./rsort to the path name of the c program # /bin/cat - | ./rsort | /usr/bin/sort -n | /bin/awk -F@ '{print $2}' ---------cut here------------- This worked for what little testing i did. The random# generations are not unique, but the sorting is random (if you call random() random). You could always keep track of what #'s you generated before....... evh@vax1.acs.udel.edu
