-bash: script.sh: /usr/bin/ksh: bad interpreter: Permission denied
提问by Matt Lmn
I have some problems with ksh. Logs says we don't have permission to access to ksh. All rights are 777 and we did the symbolic link into /usr/bin/
我对 ksh 有一些问题。日志说我们无权访问 ksh。所有权限都是 777 并且我们做了符号链接到 /usr/bin/
In /usr/bin :
在 /usr/bin 中：
lrwxrwxrwx 1 root root 8 Feb 2 10:29 ksh -> /bin/ksh
In /bin
在 /bin
lrwxrwxrwx 1 root root 21 Dec 23 11:15 ksh -> /etc/alternatives/ksh
In /etc/alternatives
在 /etc/alternatives
lrwxrwxrwx 1 root root 8 Feb 2 10:01 /etc/alternatives/ksh -> /usr/bin
Did something go wrong during installation ?
安装过程中出了什么问题？
It's quite critical for me, thanks for you help !
这对我来说很重要，谢谢你的帮助！

Going through your question:
通过你的问题：
having 777 right in any unix system exposes a huge risk, an attacker simply overwrite your executables to include a keylogger for example, so this should be avoided most of the cases. Using 755 is suitable for most of the executables instead.
alternatives is a pretty standard linux solution for having more than one alternative for a particular executable in this case ksh
I think you have to fix your script by pointing it to either /bin/ksh or /bin/ksh93
在任何 Unix 系统中拥有 777 权限都会带来巨大的风险，攻击者只需覆盖您的可执行文件以包括键盘记录器，因此在大多数情况下应该避免这种情况。使用 755 适用于大多数可执行文件。
替代方案是一种非常标准的 linux 解决方案，在这种情况下，对于特定的可执行文件有多个替代方案 ksh
我认为您必须通过将脚本指向 /bin/ksh 或 /bin/ksh93 来修复脚本
Here is the ksh installation of my system for reference:
下面是我系统的ksh安装，供参考：
[root@ ~]# which ksh
/bin/ksh
[root@ ~]# ls -larth /bin/ksh
lrwxrwxrwx 1 root root 21 Feb 2 10:21 /bin/ksh -> /etc/alternatives/ksh
[root@ ~]# ls -alrth /etc/alternatives/ksh
lrwxrwxrwx 1 root root 10 Feb 2 10:21 /etc/alternatives/ksh -> /bin/ksh93
[root@ ~]# ls -alrth /bin/ksh93
-rwxr-xr-x 1 root root 1.5M Nov 3 14:02 /bin/ksh93

Try install ksh utility on your System.

尝试在您的系统上安装 ksh 实用程序。
在终端中：yum install ksh---> 对于基于 Redhat 的系统。
