Problem with SSHEXEC and nohup

[Dave Bartmess <di...@edingo.net>]

I'm trying to do a four-task parallel call, using sshexec to call the
remote builds. Each build is a replica of the calling build, just on a
different platform. 

The build script portion is below.

The problem is, when ant executes the sshexec task, despite what I put
in the remotebuild.sh, such as "nohup ... &" (insert command for "...")
or send the command through sshexec as "nohup remotebuild.sh 2>&1
>build.log &", it won't work. It waits for the build command
inside the remotebuild.sh to complete, no matter if the build command
itself is nohup'd, or the sshexec command is nohup'd.

I could use some help. I've tried every alternative I could think of...

Thanks!

The command does not work, because you need to redirect STDxxx file 
handles to /dev/null (or some file(s)) first. You may also need to run a 
script interpreter first, or create a separate script in order to be 
able to redirect STDxxx handles.
