Diverting IDL output to the command line


Hey all,

I'm troubleshooting a batch of scripts I'm modifying, including an IDL script called by a .csh script. I'm totally new to IDL- the IDL scripts were provided to me by a coworker and my .csh script is intended to automate a lengthy set of extremely tedious and time consuming processing tasks.

I am currently in the process of debugging, and can't get the IDL to print any messages other than critical failures to the screen. Is there any easy way to redirect the stdout to either a logfile or the screen?

Thanks in advance,
Lost

stdout

If the program is a command line program, and its not printing to the screen, then it is most likely not writing to stdout to begin with. There may be verbose options that will turn on additional print-out, however I'm not familiar with the 'IDL' program off the top of my head.

If it _is_ printing a bunch of stuff to screen, but you can't capture it, the problem may be that its using stderr, in which case you can redirect stderr to a logfile like so:

Thanks for the link. Found out the issue wasn't with printing though, my variables weren't passing correctly from one function module to another. Still, this will give me something more to work with.

Thanks again,
