Shell exec takes a string which needs to be an actual command. You are now passing it a filepath. This is not interpreted as "execute the file at this path". You could do several things.
Shell exec 需要一个字符串，它需要是一个实际的命令。您现在正在向它传递文件路径。这不会被解释为“在此路径上执行文件”。你可以做几件事。
What you need to do is call the file with a program. Call it with bash or sh as suggested in the comment:
您需要做的是使用程序调用该文件。按照评论中的建议使用 bash 或 sh 调用它：
echo shell_exec('sh /home/scripts/fix-perm.sh');
Another option could be:
另一种选择可能是：
$contents = file_get_contents('/home/scripts/fix-perm.sh');
echo shell_exec($contents);
I think the first option would be better however.
不过，我认为第一种选择会更好。
It is important to note that all commands for executing external programs expect actual commands and not a filepath or something else. This goes for shell_exec, exec, passthruand others.
需要注意的是，所有用于执行外部程序的命令都需要实际命令，而不是文件路径或其他东西。这适用于shell_exec、exec、passthru等。
