Excerpts from Andreas Schwab's message of Sat Oct 10 08:24:40 -0400 2009: > According to the autoconf docs this bug is also present in the Solaris > /bin/sh (and autoconf generated scripts use some elaborated workaround). Solaris' /bin/sh shouldn't be used for anything but forking a decent shell, imo. It was brought to my attention recently that the test suite for mercurial on solaris was failing the git tests. The mercurial folks initially thought this was a git on solaris bug. After looking into it, I discovered that ^ is still treated[1] as a pipe symbol[2] in some cases. So, test suite programs run under /bin/sh on solaris with commands like `git reset --hard HEAD^` were misbehaving due to the shell setting up a pipeline under the right circumstances. -Ben [1] http://cvs.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/sh/cmd.c line 184 [2] This dates back to the Thomson shell: http://en.wikipedia.org/wiki/Thompson_shell -- Ben Walton Systems Programmer - CHASS University of Toronto C:416.407.5610 | W:416.978.4302 GPG Key Id: 8E89F6D2; Key Server: pgp.mit.edu Contact me to arrange for a CAcert assurance meeting.
