From d6b09e754c23b657544f6e7f39fbf7de24c58aa2 Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Tue, 31 Jul 2012 16:41:31 -0700 Subject: [PATCH] fault-injection: fix failcmd.sh warning "fault-injection: add tool to run command with failslab or fail_page_alloc" added tools/testing/fault-injection/failcmd.sh to make it easier to inject slab/page allocation failures by fault injection. failcmd.sh prints the following warning when running with arguments for command. # ./failcmd.sh echo aaa failcmd.sh: line 209: [: echo: binary operator expected aaa This warning is caused by an improper check whether at least one parameter is left after parsing command options. Fix it by testing the length of $1 instead of $@ Signed-off-by: Akinobu Mita Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- tools/testing/fault-injection/failcmd.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/fault-injection/failcmd.sh b/tools/testing/fault-injection/failcmd.sh index 1776e924b202..78a9ed7fecdb 100644 --- a/tools/testing/fault-injection/failcmd.sh +++ b/tools/testing/fault-injection/failcmd.sh @@ -206,7 +206,7 @@ while true; do esac done -[ -z "$@" ] && exit 0 +[ -z "$1" ] && exit 0 echo $oom_kill_allocating_task > /proc/sys/vm/oom_kill_allocating_task echo $task_filter > $FAULTATTR/task-filter -- 2.20.1
