Dear mksh developers, A customer of ours is migrating from ksh-93 to mksh. They reported the following difference in behavior:
ksh-93: $ echo X | read A $ echo $A X mksh: $ echo X | read A $ echo $A So mksh behaves the same as for example bash, in that changes to the environment of the right side of a pipe aren't reflected into the main process. That difference breaks the customer's scripts. I would like to ask if this is: 1* A deliberate design decision, and this will never change. 2* A bug, mksh should behave the same as ksh-93 in this respect. 3* Something that was not discussed so far, so status is unknown. Additionally, unless answer is 2 above, I would be grateful if you could suggest an alternative way to achieve the same with mksh. I know how I would do it with bash, but I don't know what mksh is capable of. Thanks, -- Jean Delvare SUSE L3 Support
