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
