The other reply by Andy R is spot on, you can't modify the current environment from a subshell. If you want to use the above idioms, you can use: echo "text" | (read var; echo $var) This causes the 'echo' to be run from the same subshell as 'read', so it will see the modified environment. None of this is specific to Cygwin, it's the design of sh/ash/bash type shells, and so there are better places to ask about these kinds of things than the Cygwin list. Try looking for newsgroups, FAQs, or books dealing with Bourne shell programming.
