Hi Pixelbeat,

Thanks for your quick response. We are trying this on HP UX 11. We are generating input file for sorting through c program and calling unix sort command through c only, as follows::

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

FILE *fout;
int main(int argc,char *argv[])
{
int loopcnt=0;
unsigned long int TTRECS = 60000000;

if((fout = fopen("SORTINPUT","w")) == NULL)
{
printf("\nUnable to open the output_file file\n");
exit(1);
}
for (loopcnt=TTRECS;loopcnt>=1;loopcnt--)
{
fprintf(fout,"%d|%s%d|%s|\n",loopcnt,"Dummy",loopcnt,"Dummy Description");
}
fflush(fout);
printf("Executing::sort -t '|' -k 1,1 SORTINPUT> sorttestoutput\n");

system("echo Sort Start Time;date");
system("sort -t '|' -k 1,1 SORTINPUT > sorttestoutput");
system("echo status returned::$?");

system("echo Sort End Time;date");
printf("Total Records Configured:: %lu\n", TTRECS);
return 0;
}


We are trying this test just to make sure that unix sort command is not having any limitations on file size. But what we observed is when file is packed with more than 60 million records [ around 2 Gb size], we are getting an error stating "File size limit exceeded" on console. Can u kindly state,

1] whether we got any maximum file size limit in HP UX while creating a file through C program.

2] Can unix sort command can handle file size > 2 GB without any failure.

3] Is there any restriction for length of each record [each line] or each field[fields are separated by a delimeter].

Thanks,
