linux - 突然无法运行 Shell 脚本功能

问题描述

我有一个名为“wpautobuild.sh”的文件。在该文件中，我有一个脚本，可以在 linux 服务器上自动设置开发环境和网站。

我一直wp_auto_build()在使用以下命令调用脚本中命名的函数：

$ ./wpautobuild.sh; wp_auto_build --project=abctest1

在我关闭终端会话并重新启动它之前，这一直很好。现在，当我运行相同的命令时，出现以下错误：

-jailshell: wp_auto_build: command not found

我不知道为什么我可以运行它一段时间，但现在我不能。文件中没有任何变化。诚然，我在编写 shell 脚本方面经验不足。

这是 wpautobuild.sh：

解决方案

您正在从 CLI 执行脚本，它实际上会生成一个子 shell，运行您的脚本然后终止。当它终止时，所有创建的环境变量和函数都会被丢弃。它们永远不会到达您当前的shell，因此您不能从脚本中定义的 shell 调用函数。

如果要定义当前环境中可用的函数，则需要source定义这些函数的脚本，或者，因为这符合 POSIX，所以使用.. 通常，在定义行为类似于自定义内置命令的函数时，您将函数定义添加到.bashrc或类似的东西，或者您source从那里添加脚本。

我实际上想知道为什么你能打电话给你wp_auto_build一段时间。我假设您通过将脚本从您最喜欢的文本编辑器直接粘贴到 shell 中来测试您的脚本。这确实在您当前的环境中定义了变量和函数。
