linux – Bash：运行可执行文件,提供良好的退出状态

我想在 Linux中运行一个可执行文件,无论它返回的退出状态如何,我都希望返回一个良好的退出状态. (即没有错误.) @H_502_2@(这是因为我正在使用sh -ex,即使一个(特定)命令失败,我也希望脚本继续运行.)

解决方法

尝试一下：

command || true

@H_502_2@来自man bash：

@H_502_2@The shell does not exit if the command that fails is part of the command list immediately following a while or until keyword,part of the test following the if or elif reserved words,part of any command executed in a && or ⎪⎪ list except the command following the final && or ⎪⎪,any command in a pipeline but the last,or if the command’s return value is being inverted with !.
