当我通过 ssh 或从控制台登录时，我看到的是：

-bash: id: command not found
-bash: [: : integer expression expected
root@sensu:~#
这是什么以及如何摆脱它？
-bash: id: command not found
-bash: [: : integer expression expected
我无法执行大多数命令，它说command not found instead
谢谢。
答案1
它最终是由错误的 /etc/environment 文件引起的。
答案2
是所有用户都会出现这种情况还是只有 root 用户会出现这种情况？如果是每个人，请尝试在 /etc/profile.d 下查找最近修改的脚本（因为问题开始发生）。您可以find /etc/ -path *profile* -mtime -5 查找最近 5 天内修改的内容。如果它只是针对 root，请尝试首先查看 /root/.bashrc 是否有一些错误的脚本。
