Hi,

If I run the this two line script:

  trap 'echo EXIT trap executed' EXIT
  kill -HUP $$

I would expect it to display "EXIT trap executed", but it does not
display anything.

(If I add a HUP trap, both the HUP trap and the EXIT trap are executed.)

Cheers,
Martin

thanks

I am adding this bug to the dash as /bin/sh RG because IMHO it is relevant.
This bug has actually affected some scripts I wrote and is kind-of annoying.

Thanks,

Hi, I got no response from upstream yet.  I applied the patch to
0.5.5.1-1, but it unfortunately causes severe problems (#515229,
#515064), so I removed it again in 0.5.5.1-2.

Regards, Gerrit.

I was never particularly confident in it, hence my desire to see
upstream comment on it.


Regards,

I just was bitten by this. Is there a workaround?
