Subject: How to save and restore traps?
Date: Thu, 08 Jan 1998 14:11:01 +0100	[thread overview]
Message-ID: <34B4D065.F6DF5754@rrz.uni-hamburg.de> (raw)

I'd like to save the traps at the start of a function and restore them
before returning. This would be nice if it worked:

   function f
   { typeset oldtraps=$(traps)
     # ...
     eval $oldtraps
     return
   }

Unfortunately it doesn't, because the command in $(...) gets executed in
a subshell (IMHO the manual should mention that!), so that all traps
initially are reset to their defaults.

Any idea how to achieve this without redirecting the output of 'trap' to
a file?

Regards,
	Bernd
