可執行腳本在 Linux 機器上獲得權限被拒絕 (Executable script gets permission denied on Linux box)

問題描述

可執行腳本在 Linux 機器上獲得權限被拒絕 (Executable script gets permission denied on Linux box)

嘗試在 Ubuntu 14.04 上運行腳本。

$ bash MirroirHome

運行良好

但是

$ ./MirroirHome
bash: ./MirroirHome: Permission denied

$ ls ‑l
total 32
‑rwxr‑xr‑x 1 gerald gerald  214 nov 14 15:44 MirroirHome

我是文件的所有者，權限位是上，發生了什麼？

這是腳本以防萬一。

#!/bin/bash
rsync \
‑‑archive \
‑‑verbose \
‑‑compress \
‑‑update \
‑‑delete \
/home/ /media/Data/MirroirHome

參考解法

方法 1:

This can happen if the partition is mounted with the noexec flag on. You can verify this by running mount: find the partition in the output, and in the list of flags, probably there will be noexec.

To resolve this, remount the partition without the noexec flag. Or, copy the script to another partition that's already mounted without noexec.
