Since these all have #! lines, can you please set the executable bit on any that don't have it set (looks like just config2frag.sh and kvm.sh), and then change the Usage lines to drop the shell entirely and just invoke the program directly? > Signed-off-by: Pranith Kumar <bobby.prani@...il.com> With the above changed (perhaps in a separate patch): Reviewed-by: Josh Triplett <josh@...htriplett.org> > tools/testing/selftests/rcutorture/bin/config2frag.sh | 4 ++-- > tools/testing/selftests/rcutorture/bin/configcheck.sh | 4 ++-- > tools/testing/selftests/rcutorture/bin/configinit.sh | 4 ++-- > tools/testing/selftests/rcutorture/bin/kvm-build.sh | 2 +- > tools/testing/selftests/rcutorture/bin/kvm-recheck-lock.sh | 2 +- > tools/testing/selftests/rcutorture/bin/kvm-recheck-rcu.sh | 2 +- > tools/testing/selftests/rcutorture/bin/kvm-recheck.sh | 2 +- > tools/testing/selftests/rcutorture/bin/kvm-test-1-run.sh | 2 +- > tools/testing/selftests/rcutorture/bin/kvm.sh | 2 +- > tools/testing/selftests/rcutorture/bin/parse-build.sh | 4 ++-- > tools/testing/selftests/rcutorture/bin/parse-console.sh | 4 ++-- > tools/testing/selftests/rcutorture/bin/parse-torture.sh | 4 ++-- > 12 files changed, 18 insertions(+), 18 deletions(-) > > diff --git a/tools/testing/selftests/rcutorture/bin/config2frag.sh b/tools/testing/selftests/rcutorture/bin/config2frag.sh > index 9f9ffcd..4e394ef 100644 > --- a/tools/testing/selftests/rcutorture/bin/config2frag.sh > +++ b/tools/testing/selftests/rcutorture/bin/config2frag.sh > @@ -1,5 +1,5 @@ > -#!/bin/sh > -# Usage: sh config2frag.sh < .config > configfrag > +#!/bin/bash > +# Usage: bash config2frag.sh < .config > configfrag > # > # Converts the "# CONFIG_XXX is not set" to "CONFIG_XXX=n" so that the > # resulting file becomes a legitimate Kconfig fragment. > diff --git a/tools/testing/selftests/rcutorture/bin/configcheck.sh b/tools/testing/selftests/rcutorture/bin/configcheck.sh > index d686537..6173ed5 100755 > --- a/tools/testing/selftests/rcutorture/bin/configcheck.sh > +++ b/tools/testing/selftests/rcutorture/bin/configcheck.sh > @@ -1,5 +1,5 @@ > -#!/bin/sh > -# Usage: sh configcheck.sh .config .config-template > +#!/bin/bash > +# Usage: bash configcheck.sh .config .config-template > # > # This program is free software; you can redistribute it and/or modify > # it under the terms of the GNU General Public License as published by > diff --git a/tools/testing/selftests/rcutorture/bin/configinit.sh b/tools/testing/selftests/rcutorture/bin/configinit.sh > index 9c3f3d3..d8f7418 100755 > --- a/tools/testing/selftests/rcutorture/bin/configinit.sh > +++ b/tools/testing/selftests/rcutorture/bin/configinit.sh > @@ -1,6 +1,6 @@ > -#!/bin/sh > +#!/bin/bash > # > -# sh configinit.sh config-spec-file [ build output dir ] > +# bash configinit.sh config-spec-file [ build output dir ] > # > # Create a .config file from the spec file.
