[X-Unix] Cron problem solved

[Robert Frank]

The $(...) actually starts a sub shell, then returns the result. In  
the below fragment, you can simply write:

for screen in mg*
do
   ...
done

provided you are in the directory with the screen shots when the  
script starts, and file globbing is not turned off. There is no need  
to run a subshell in order to get a list of files. The list is  
automatically composed by simply using 'mg*'.

And: you could of course immediately promote the files to pdf in the  
capture script:

cd /path/to/dir/with/screen/shots
now=`/bin/date "+%H%M%S"` # note the two backtics!
  /usr/sbin/screencapture mg$now
/path/to/ps2pdf mg$now            # substitute the /path/to
/bin/rm mg$now


The next step is, of course, to archive these shots from time to time  
(e.g. once a month), then to get rid of them when no longer used  
(e.g. after one year).
