Re: local/non-local and sub shell exit codes

[René Neumann <lists@xxxxxxxxx>]

Ok, I have to take it back. Found the following in the manpage (after
discovering, that 'local' is an alias for 'typeset'):

---8<---
Unlike parameter assignment statements, typeset's exit status on an
assignment that involves a command substitution does not reflect the
exit status of the command substitution. Therefore, to test for an error
in a command substitution, separate the declaration of the parameter
from its initialization:
  # WRONG
  typeset var1=$(exit 1) || echo "Trouble with var1"

  # RIGHT
  typeset var1 && var1=$(exit 1) || echo "Trouble with var1"
