[Help-bash] Option execfail does not work in subshells

[R. Diez]

Hi all:

When I run this test script:


#!/bin/bash

test ()
{
  shopt -s execfail
  exec "non-existing-command"
  echo "This message should therefore always appear."
}

test
(test)
test &



The output is:

$ ./execfail-test.sh
./execfail-test.sh: line 6: exec: non-existing-command: not found
This message should therefore always appear.
./execfail-test.sh: line 6: exec: non-existing-command: not found
./execfail-test.sh: line 6: exec: non-existing-command: not found


That is, it looks like execfail is being ignored in the subshells.

Is that a bug? Or have I missed something?

Thanks in advance,
