[Nauty-list] Shortging large files

[Bulutoglu Dursun A Civ AFIT/ENC]

I have a file in the called temp.s6 which takes up 2.0G of disk space.
I run the below command to shortg it and I get the response below.

/home/afiten3/fac/dbulutog/nauty24b7/shortg -T/work/srtdump -vu <temp.s6
>A shortg -vuT/work/srtdump
>E readg: missing newline
>E gtools: Illegal seek

I was wondering how I can shortg a file that takes up more than 2.0G
of disk space.

Thanks in advance.

Dursun.

PS: I have  more than enough disk space in the srtdump directory where
the sort utility of linux is being used.
