I run the command:
Code:
fxheader *.fz lo+ > z

and everything is going well except one file (which is a correct one in DS9):
Code:
Warning: Cannot open file (q1186.fits.f)

The file "q1186.fits.fz" exists and I can make:
Code:
fitsutil> fxheader q1186.fits.fz lo+

with no problem.

How many images does the template "*.fz" turn out to be? I noticed the warning message prints the image name as "...fits.f" and not "...fits.fz" so I'm wondering whether the template expansion may be truncating the name in list somehow.

One way to test this is to set

Code:

    cl> reset use_new_imt = no
    cl> flpr 0                            # zero, not oh


This will use the older template code and if it then works would help confirm the truncation. OTOH, it could be something like unitialized code in the task, but I'm not able to reproduce the problem myself. If you still have problems, could you tell me what IRAF version and platform you're using? If its v2.16, are you sure you're running the latest update?

As we can see from the pattern fxheader *.fz lo+ > z there must be a bug in the task. There is a file number (1186) in the file name, so the template list is rather big.

I updated today the iraf 2.16 to:
Code:
NOAO/IRAF PC-IRAF Revision 2.16 EXPORT Thu May 24 15:41:17 MST 2012

and the the situation is the same:
Code:
fitsutil> fxheader *.fz lo+ > zz
Warning: Cannot open file (q1186.fits.f)
fitsutil> reset use_new_imt = no
fitsutil> flpr 0
fitsutil> del zz
fitsutil> fxheader *.fz lo+ > zz
fitsutil>

As we can see, there is no problem when I reset use_new_imt.

I do remember fixing a bug with long-template expansion recently and it appears this was done in the dev system after the last binary release of the external packages. The extpkg distros have just been updated so I'd suggest doing

Code:

    % cd $iraf/extern
    % make fitsutil


to reinstall the FITSUTIL package binaries. A "cd $iraf ; make latest" will also make sure the core IRAF system and remaining packages are updated as well.

I did today:
Code:
cd $iraf
make latest

and after starting it I got:
Code:
fitsutil> fxheader *.fz lo+ > zz

The Ctrl-C brakes it with: PANIC in `/iraf/iraf/extern/fitsutil/bin.linux/x_fitsutil.e': software terminate (interrupt) and then lo gives: Abnormal termination of child process 'fitsutilbin$x_fitsutil.e'
Fatal logout error. CL dies..
Anyway when I start IRAF again:
Code:
cl
vocl> fitsutil
fitsutil> fxheader b0001.fits.fz lo+

I get a correct answer and NO IRAF PANIC.

I can confirm there's still a problem in the template code for very long strings and will fix it for the next update. Until then, use the workaround. I'll let you know when the update is available.
