sort uses the directory specified by the environment variable TMPDIR. If it is not set sort then uses /tmp (consult your man page for sort some may use /var/tmp). A few versions of sort accept a

-T <directory>

option as well to redirect temp files.

Hi.

The man page usually discusses how to specify the location where temporary files are placed. For example:
Quote:
-T directory Specifies the directory in which to place
temporary files.

-- excerpt from Solaris man sort
However, you may be running into problems with large files:
Quote:
A large file is a regular file whose size is greater than or
equal to 2 Gbyte ( 2**31 bytes). A small file is a regular
file whose size is less than 2 Gbyte.

-- excerpt from Solaris man largefile
The Solaris sort knows how to deal with such files, but not all commands do.

Best wishes ... cheers, drl
