从Java/Groovy运行复合Shell命令 [英] Run a compound shell command from Java/Groovy

问题描述

我在尝试从Groovy脚本运行复合shell命令时遇到了麻烦.这是您使用&&"分隔的命令之一因此，如果第一个命令失败，则第二个命令将永远不会运行.无论出于什么原因，我都无法正常工作.我正在使用:

I got stuck trying to run a compound shell command from a Groovy script. It was one of those commands where you separate with "&&" so that the 2nd command never runs if the 1st one fails. For whatever reason I couldn't get it to work. I was using:

println "custom-cmd -a https://someurl/path && other-cmd -f parameter".execute([], new File('/some/dir')).text

shell不断误解命令抛出的错误，例如"custom-cmd -f无效选项"，就像忽略了&&"一样在两者之间.我也尝试使用分号，但并不幸运.我尝试使用直接的Java API Runtime.getRuntime().exec()并将命令拆分为一个数组.我尝试将命令包装在单引号中，并将其提供给'/bin/sh -c'，但没有任何效果.

The shell kept misinterpreting the command throwing errors like "custom-cmd -f invalid option" It was like it was ignoring the "&&" in between. I tried using a semi-colon as well but was not lucky. I tried using straight Java APIs Runtime.getRuntime().exec() and splitting the command into an array. I tried wrapping the command in single quotes and giving it to '/bin/sh -c' but nothing works.

如何从Java运行复合shell命令?我知道我过去曾经做过，但是今天我不知道.

How do you run a compound shell command from Java? I know I've done this in the past but I cannot figure it out today.

推荐答案

使用Groovy，execute的列表形式应该起作用:

With groovy, the list form of execute should work:

def out = ['bash', '-c', "custom-cmd -a https://someurl/path && other-cmd -f parameter"].execute([], new File('/some/dir')).text

当然，您可能希望在进程上使用 consumeProcessOutput 方法，就像输出太大一样，调用文本可能会阻塞

Of course you may want to use the consumeProcessOutput method on process, as if the output is too large, calling text may block
