linux命令用于读写和可执行权限

Question

我正在linux盒子上选择一些路径进行安装.例如/ var/test/installer如何检查该路径的读,写和执行权限是否可用？

我确实试过"查找命令",但没有取得很大的成功.

伙计们,做"ls -l"并没有帮助我.这是一个真正的问题......我的/ var分区没有执行权限.我可以通过在/ var type ext3上使用"mount"命令ie> mount/dev/sda1来看到(rw,noexec,nosuid,nodev,noatime)

但是ls -l表示/ var ie下的任何文件夹./ var/test/install显示了读,写和执行权限.

所以我只看到grep mount命令检查noexec的方法.

你的意见.

提前致谢.

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

我最终理解的是,我必须检查两级权限

1. Mount Point的权限

   使用"mount"命令或检查/ etc/fstab文件

2. 单个文件夹的权限

   Usinf"ls -l"命令

这解决了我的问题.
