"read"

[Gabor Kiss [Bitman]]

Dear folks,

bash(1) man page should be extended a bit. :-)

       read [-er] [-a aname] [-p prompt] [name ...]
                ...
                Common pitfalls:
                        command | read var
                In this construct the outermost shell forks a subprocess
                for "read". "Read" sets variable "var" _in_his_own_
                environment, that will not effect the calling shell's
                environment.

Regards

Gabor
