如何在Groovy中执行shell命令并获取返回代码$? [英] How to execute shell command in Groovy and get the return code $?

问题描述

我无法通过在Groovy中执行shell脚本来获取返回代码(不是输出或错误).

I can't get the return code (not the output or error) from executing a shell script within Groovy.

对于我尝试过的所有操作，它要么要求我退出，要么只打印$?而不是给我1或0.

For all what I tried, it either ask me to escape or just print the $? instead of give me 1 or 0.

groovy:75:美元符号后的非法字符串体字符； 解决方案:在第75行的第24列中，转义文字美元符号"\ $ 5"或将值表达式"$ {5}"括在括号中.

groovy: 75: illegal string body character after dollar sign; solution: either escape a literal dollar sign "\$5" or bracket the value expression "${5}" @ line 75, column 24.

下面是我尝试过的解决方案，所有方法均无效.

Below are solutions I tried, all don't work.

println "../src/check_job_log.s ${it}.log".execute().text
println "Check log ${it}.log completed"

//assert ("echo \$?".execute().text == "1")
//output = """echo $?""".execute().text
println(['echo', '$?'].execute().text)

// below is code for  @that other guy
//def process = "echo hello world".execute()
def process = "../src/check_job_log.s ${it}.log".execute()
print "Output: " + process.text
print "Exit code: " + process.exitValue()

Output: Exit code: 01

推荐答案

使用Process.exitValue()代替.text(或除.text之外):

Use Process.exitValue() instead of (or in addition to) .text:

def process = "echo hello world".execute()
print "Output: " + process.text
print "Exit code: " + process.exitValue()
