bash exit command should be unconditional

[Vadym Chepkov]

Hi,

I found out a very unusual feature of bash which makes it to act really 
unexpected. I understand that pipelines are executed in a separate subshell, 
but I really think 'exit' command should be absolute. Consider a trivial code:

#!/bin/bash

echo Start
ps -ef | while read proc
do
 echo $proc
 exit 1
done
echo Continue

I would expect never see "Continue" printed, I didn't put any conditional 
checks to simplify the example, but I really expect the script to be completely 
aborted when it gets to 'exit', not having to add additional checks or replace 
pipeline with temporary files

Sincerely yours,
  Vadym Chepkov
