There is a pretty comprehansive answer at https://unix.stackexchange.com/questions/364/allow-setuid-on-shell-scripts Bottom line is that there are two main points against it: A race condition between when the Kernel opens the file to find which interpreter it should execute and when the interpreter opens the file to read the script.

To enable changing file owners & permissions, you need to edit /etc/wsl.conf and insert the below config options: [automount] options = “metadata” Do this inside the WSL shell, potentially needing sudo to edit/create the file. This may require restarting WSL (such as with wsl –shutdown which is a Windows command, not one within WSL) or … Read more
Use os.stat() to get the current permissions, use | to OR the bits together, and use os.chmod() to set the updated permissions. Example: import os import stat st = os.stat(‘somefile’) os.chmod(‘somefile’, st.st_mode | stat.S_IEXEC)
If you are going for a console command it would be: chmod -R 777 /www/store. The -R (or –recursive) options make it recursive. Or if you want to make all the files in the current directory have all permissions type: chmod -R 777 ./ If you need more info about chmod command see: File permission

Here is a small incomplete list of possible attack vectors: “your safe code” could be overwritten with “their … Read more
This is the most restrictive and safest way I’ve found, as explained here for hypothetical ~/my/web/root/ directory for your web content: For each parent directory leading to your web root (e.g. ~/my, ~/my/web, ~/my/web/root): chmod go-rwx DIR (nobody other than owner can access content) chmod go+x DIR (to allow “users” including _www to “enter” the … Read more
The other answers are correct, in that chmod -R 755 will set these permissions to all files and subfolders in the tree. But why on earth would you want to? It might make sense for the directories, but why set the execute bit on all the files? I suspect what you really want to do … Read more
Here’s one scenario: You have an unprotected directory that users can upload to. They upload two files: a shell script, and a php file that has a system() call in it to the shell script. they access the php script they just uploaded by visiting the url in their browser, causing the shell script to … Read more
An easy way is to let PHP create the directory itself in the first place. <?php $dir=”myDir”; // create new directory with 744 permissions if it does not exist yet // owner will be the user/group the PHP script is run under if ( !file_exists($dir) ) { mkdir ($dir, 0744); } file_put_contents ($dir.’/test.txt’, ‘Hello File’); … Read more
