Illegal seek

Cause

Using a pipe ("|") on the command line doesn't work here.

Action

Rather than using a pipe on the command line, redirect the output of the first program into a file and run the second program on that file.

Technical Notes

A call to lseek(2) was issued to a pipe. This error condition can also be fixed by altering the program to avoid using lseek(2).

The symbolic name for this error is ESPIPE, errno=29.
