Hello, It's not a bug, both are POSIX, placing a pipe member in the current environment instead of in a subshell being an extension:
Command substitution, commands that are grouped with parentheses, and asynchronous lists shall be executed in a subshell environment. Additionally, each command of a multi-command pipeline is in a subshell environment; as an extension, however, any or all commands in a pipeline may be executed in the current environment. http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_12 ++ Seb. -- To unsubscribe from this list: send the line "unsubscribe dash" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
