test1.sh中的变量A并显示出来了。 其实直接运行脚本的方式产生的效果同使用bash指令的一样,关于这三种脚本的运行方式可以阅读Bash脚本的运行方式。 从上面的例子中不难发现,使用source的方式会发现,export后的变量变成了当前Shell的环境变量,可以在当前Shell环境下打印一下变量A。 [root@amt01 article002]#echo$A H...
From this example above, it is clear the child processes don’t inherit parent shell processes even when forked from the parent process. At this point, bash scripters introduce the export command. Hence, there is a new script, looking like the one below: You can see that the export command...
To alter the environment, you have the option to pass either (as your command already does) or to wipe out all current environment variables and begin anew. Additionally, you can pass key=value pairs on the command line to establish new values. As a solution, when you initially use it...

./script argument 例子: 显示文件名称脚本 ./show.sh file1.txt cat show.sh #!/bin/bash echo $1 (LCTT 译注:谢谢某匿名访客的提醒,原题有误,修改之。) 2) 如何在脚本中使用参数 ? 第一个参数 : $1,第二个参数 : $2 例子: 脚本会复制文件(arg1) 到目标地址(arg2) ...

...在构建环节中简单加入这一字段即可,例如: jar: stage: build tags: - maven script: - mvn package artifacts: paths: - target...这里生成的 JAR 文件将在后续用来构建 Docker 镜像。 在 Pod 内构建 Docker 镜像 Docker 提供了一个 dind 镜像,意思就是“Docker in Docker”。
