linux 错误码13是什么问题？
linux服务器下出现permission denied [13]错误
这个错误在linux下出现就是权限的问题，如果是用服务器的，可以安装xshell，有对应的xftp文件，是一个图形化界面，在对应的文件夹下点击右键就会有一个更改权限，把权限改为777就可以了，777代表可写可读可执行。
如果这样操作还不行，可以在服务器的黑框屏幕里面输入chmod 777 加上对应要修改权限的目录或者文件 ， 这样就可以把对应的权限改掉了。
我之前碰到的错误就是这样的，在实验室上面换了环境，需要用到另一个环境下的自己创建的文件，结果权限不够，一直没明白什么意思，后来才知道是这样子的。
或者不执行前面的，直接执行标黑粗的部分就行。因为前面图形化界面的有可能不管用，我之前安装matlab这样执行是可以的，但是出现这个错误这样执行，我的没效果，因为改了以后又变回原来的样子了，至于为啥，我也不清楚，可能是软件的原因，但是如果本身就有这个软件的同学可以用这个改，看看管用不。因为有的人不喜欢在黑屏里面操作。
