From 721307eba0e7d94241698936c58352ee3c6da748 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 20 Dec 2022 07:25:59 +0100 Subject: cmd: exit: Fix return value propagation out of environment scripts Make sure the 'exit' command as well as 'exit $val' command exits from environment scripts immediately and propagates return value out of those scripts fully. That means the following behavior is expected: " => setenv foo 'echo bar ; exit 1' ; run foo ; echo $? bar 1 => setenv foo 'echo bar ; exit 0' ; run foo ; echo $? bar 0 => setenv foo 'echo bar ; exit -2' ; run foo ; echo $? bar 0 " As well as the followin behavior: " => setenv foo 'echo bar ; exit 3 ; echo fail'; run foo; echo $? bar 3 => setenv foo 'echo bar ; exit 1 ; echo fail'; run foo; echo $? bar 1 => setenv foo 'echo bar ; exit 0 ; echo fail'; run foo; echo $? bar 0 => setenv foo 'echo bar ; exit -1 ; echo fail'; run foo; echo $? bar 0 => setenv foo 'echo bar ; exit -2 ; echo fail'; run foo; echo $? bar 0 => setenv foo 'echo bar ; exit ; echo fail'; run foo; echo $? bar 0 " Fixes: 8c4e3b79bd0 ("cmd: exit: Fix return value") Reviewed-by: Hector Palacios Signed-off-by: Marek Vasut --- doc/usage/cmd/exit.rst | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'doc/usage') diff --git a/doc/usage/cmd/exit.rst b/doc/usage/cmd/exit.rst index 769223c4775..3edb12809ce 100644 --- a/doc/usage/cmd/exit.rst +++ b/doc/usage/cmd/exit.rst @@ -37,4 +37,6 @@ executed.
