I get this error message, any idea what this means?

Code:


PANIC in `/Users/IRAF/iraf/iraf/bin.macintel/x_system.e': Write to IPC with no reader
ERROR: IRAF Main: command syntax error
  "copy ( cal_dir//dbname//"/id"//arcwave//"*",database_dir//dbname//"/ ..."
     line 669: wifes$wfreduce.cl
     called as: `wfreduce ()

Does this look like a problem with iraf installation?

The message basically means there was an error in the COPY task and communication with the CL was terminated. You can type 'd_trace' before running the task (or insert a print statement in the script) to find out exactly what the parameters are, if you can then reproduce this behavior outside the script then I'll need to know more about the file (or have access to it) to reproduce and debug the problem. If it only happens in the script then it could be an error in the script of some kind.

Otherwise, there's not enough information to speculate what else might be going on.

When I do d_trace and hen run the task the output is too small, and even with the scrollbar I can's see all the output, is there a way to fix that?

Try redirecting the output to a file (I'm not sure what you mean by "too small"), e.g.

Code:
cl>  wfreduce >& /tmp/trace.txt


The last screenful or so of the output is really all you need.

And how can I see the output?
I assume there is a file created called trace, but I don't know where to find that file Sad

Redirecting the output as I showed will put the output to the file you named 'trace.txt' instead of the screen. When the task is done, look at the file using whatever tool you would normally use to look at a text file.
