pipe report output to another server

mirx · #1 (**permalink**) 04-04-2009

I have access to an AIX 5.3 box, where I need to write a report to:
/tmp/report
The report is larger then the amount of available disk space on the box.
There's about 1 GB of free space, for a 1.5 GB report.

The report is destined for another box (10.0.0.2) anyway, which has enough free space.
This report gets run weekly. Currently we have to split the report into chunks and transfer the parts separately.
What I'm thinking might be an option is to create a named pipe to send the report to the other box using ftp or scp (or curl if I have to but its not currently installed).

What I'm not sure about is how to do this:
Create /tmp/report before I run the report as some type of named pipe that directs to:
|scp user@10.0.0.2:/lots_of_space/report
then have the app write the report to /tmp/report, where the pipe send it to my other box. I'm also not sure if the app writing the report will just try to over write the file/pipe at /tmp/report instead of piping it.

I pretty familiar with unix, but I haven't done much in the lines of named pipes or piping across the network.

Thanks in advance for any help!

Code:

[ -f /tmp/report ] && rm /tmp/report
mkfifo /tmp/report
report_command &
ssh user@10.0.0.2 "cat > report" < /tmp/report
rm /tmp/report
