我不知道该怎么命名。欢迎标题建议。
我使用zsh作为我正在使用的用户的默认shell。每当我尝试运行一个使用bash的脚本时，它就会启动一个新的zsh登录shell，而不是运行该脚本。如果我更改#/bin/bash行到#/usr/bin/zsh它只是工作。踢球者来了。一旦新的shell启动，脚本就从那时开始正常工作
我正在使用vcxsrv作为X服务器的mate终端。我最初启动了一个普通的ubuntu bash终端，然后我用它来生成mate终端，因为在启动mate终端之前，我需要DISPLAY var设置。不管怎样，这是我要开始的剧本。
同样需要注意的是，如果我通过将bash设置为默认值并在脚本中使用zsh来反转shell，那么同样的事情就不会发生。
我如何让它只运行脚本？

关键是/etc/bash.bashc 中的这一行
source /usr/sbin/start-systemd-namespace
回来后，我根据网上其他地方的指示进行了系统工作。它一定添加了这一行。当您使用另一个类似zsh的shell时，它会启动一个全新的shell。说完了，瞧，没问题了。
