用于读写和可执行权限的linux命令

Question

我在 linux box 上选择一些路径进行安装。例如/var/test/installer如何检查该路径是否具有读取、写入和执行权限？

我确实尝试过“find command”，但没有取得太大的成功。

伙计们，执行“ls -l”对我没有帮助。这是一个真正的问题......我的/var 分区没有执行权限。我可以通过使用“mount”命令看到即 > 安装/dev/sda1 on/var type ext3 (rw,noexec,nosuid,nodev,noatime)

但 ls -l 用于/var 下的任何文件夹，即。/var/test/install 显示读取、写入和执行权限。

所以我只看到了 grep 挂载命令来检查 noexec 的方法。

你的想法。

提前致谢。

=============================================

我最终理解的是我必须检查两个级别的权限

1. 挂载点权限

   使用“mount”命令或检查/etc/fstab 文件

2. 单个文件夹的权限

   使用“ls -l”命令

这解决了我的问题。
