[Xen-devel] [OSSTEST PATCH 04/16] mg-debug-fail: New utility script for debugging

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

Signed-off-by: Ian Jackson <Ian.Jackson@xxxxxxxxxxxxx>
Acked-by: Ian Campbell <ian.campbell@xxxxxxxxxx>

v2: Use "egrep ''" rather than "egrep .".  Both sanitise
     missing-final-newline but "egrep ''" will print blank lines,
     which is desirable here.

+#
+# This script can be provided anywhere an executable or command name is
+# wanted.  It prints its arguments, and its stdin, to its stderr, and
+# then exits nonzero.
+#
+# When using this it may be useful to provide </dev/null as a
+# redirection for the whole program under test.  Otherwise things
+# can mysteriously hang.
