特定命令的Bash忽略错误

Question

set -o pipefail
set -e

Answer 1

解决方案：

particular_script || true

示例：

$ cat /tmp/1.sh
particular_script()
{
    false
}

set -e

echo one
particular_script || true
echo two
particular_script
echo three

$ bash /tmp/1.sh
one
two

三将永远不会打印。

$ set -o pipefail
$ false | true ; echo $?
1
$ set +o pipefail
$ false | true ; echo $?
0
