最终在shell中编写try catch [英] Writing try catch finally in shell

问题描述

是否有像Java try catch一样的linux bash命令? 还是linux shell总是会继续运行?

Is there a linux bash command like the java try catch finally? Or does the linux shell always go on?

try {
   `executeCommandWhichCanFail`
   mv output
} catch {
    mv log
} finally {
    rm tmp
}

推荐答案

好吧，

{ # your 'try' block
    executeCommandWhichCanFail &&
    mv output
} || { # your 'catch' block
    mv log
}

 rm tmp # finally: this will always happen
