我s2cmd在我的 unix 机器上安装了一个包。当我从它所在的文件夹运行它时，它工作正常，但它无法从其他位置运行，因此我使用命令设置了 PATH，该文件夹中export PATH=$PATH:/opt/bitnami/S3Tools/s3cmd-1.5.0-alpha1有一个s3cmd必须执行的文件。
现在的问题是，当我执行 时which s3cmd，我得到了正确的路径作为输出，但是当我使用 运行它时，sudo s3cmd它会说command not found。如果我给出绝对路径并尝试运行它，它会从任何位置运行。
我究竟做错了什么？
编辑 ：我刚刚注意到有 2 个 PATH 变量具有相同的路径。这会导致问题吗？如果是，我该如何纠正？
