svn commit: r205136 - head/tools/regression/bin/sh/errors

[Jilles Tjoelker]

New Revision: 205136
URL: http://svn.freebsd.org/changeset/base/205136

Log:
  sh: Add test for assignment errors (e.g. trying to change a readonly var).
  We currently ignore readonly status for assignments before regular builtins
  and external programs (these assignments are not persistent anyway), so just
  check that the readonly variable really is not changed.
  The test depends on the command builtin changes for 'command :'.

Added:
  head/tools/regression/bin/sh/errors/assignment-error1.0   (contents, props changed)

Added: head/tools/regression/bin/sh/errors/assignment-error1.0
