The '/root' directory is often not world-readable.  Try putting the
file under '/tmp' or '/var/tmp', and remember that the file will be
read as the "postgres" user (or whatever your database server runs
as).

Don't forget that you'll need to set permissions on all the intermediate
directories as well as the file itself. It is probably safer to put the
file somewhere else than to make /root world-accessible. /tmp or an
ordinary user's home directory would be possibilities.

*wild guessing* Is desktop and server the same
machine? If not, you cannot use the copy command
that way. If you issue a copy command with a path
to a file, the backand on the server has to find
the file. If its on your desktop, this operation
will not succeed.

Either you copy your file to the server in that case
or use copy from stdin with psql.

Thanks to all...  it's importing now.  I'm still learning Linux after
upgrading from Windows.  Moving the file to another dir (\tmp) did it.   Jon
