[PATCH] hush - non-interactive-shell-job-fix

[Bayram Kurumahmut]

Some script files were not returning to the shell before this fix.

cmd1
cmd2
cmd3 & ----> this line was causing problems.
cmd4

A comment extracted from hush:

"....non-interactive bash does not continue if all processes in fg pipe are stopped...."

It seems that we must return if there is no stopped or alive process in non-interactive shell. If we don't, code is stopping on waitpid() but there is no process to wait.

Regards,
Bayram
