Rajiv,

The way to do this in UN*X is to

compress <file_name> this will produce <file_name>.Z and extra space mkfifo derf (create a named pipe)
write a program lf that reads stdin and writes stdout with linefeeds. uncompress -c <file_name> |lf > derf &
sqlload derf

What this does is create a pipe (typically a 4K buffer in memory) That looks like a file to sqlload. The contents of the named pipe will be what ever you redirected (>) into it. Once done it will once again be empty unless you redirect something else into it.

Please not the & at the end of the uncompress line. You MUST but the uncompress line in backgroud

Hope this helps
