Patch provided by Martin Wilke via PR 34313. [osh-060124]: Makefile: * Added targets for building/installing sh6(1) and glob6(1). Refer to the README file for further details. * Removed the `check-sh6' target since the tests were originally written for osh(1) and sh6(1) as Thompson-shell reimplementations, not ports. sh6: * Changed sh6(1) from being a reimplementation which is compiled from the same sources as osh(1) to being a port of the original Thompson shell from Sixth Edition Unix. Refer to the CHANGES_sh-to-sh6 file for further details. osh: C: Treat both `( ; )' and `( & )' as syntax errors. C: Print the process ID for each command of an asynchronous pipeline, not just the last command. C: Added the `newgrp' special command. It is similar to `login' except that the newgrp(1) utility replaces the current interactive shell rather than the login(1) utility. * When opening `/dev/null' is needed for an asynchronous command, call open(2) w/ the O_RDONLY flag instead of O_RDWR. |
