I'm currently running OpenBSD 6.0-release and I believe I found a bug in the default shell pdksh.
I've written about it in detail in this StackOverflow post: http://stackoverflow.com/questions/41614964/ksh-errexit-on-conditional-execution/41617070#41617070 To summarize, the following script will not correctly terminate on the second iteration of the loop: set -ex for a in 1 2 3; do [ $a == 1 ] || false done On bash, and apparently more recent shells in general, the script terminates on the second iteration. I do not have the time to provide a source code fix myself, so I am reporting about this on misc.
