Changing permissions recursively with chmod:

chmod -R 755 path_to_folder
Works

chmod --recursive 755 path_to_folder
Works

chmod -r 755 path_to_folder
DOES NOT WORK chmod: cannot access '755': No such file or directory

From man chmod:

The perm symbols represent the portions of the mode bits as follows:
r The read bits.

The op symbols represent the operation performed, as follows: - If no value is supplied for perm, the ``-'' operation has no effect. If no value is supplied for who, each permission bit specified in perm, for which the corresponding bit in the file mode creation mask is set, is cleared. Otherwise, the mode bits represented by the specified who and perm values are cleared.

Therefore -r tries to remove the read bits from directory 755, which obviously does not exist and therefore throws an error.

The screen terminal utility allows for the continous running of terminal jobs - even when the user is logged out:

1. Start a new session with screen.
2. Dettach screen: control-a, d
3. List all screens: screen -list
4. Re-attach screen: screen -r

• Remove dead screen: screen -wipe

Instead of yyping the whole Tailwind command, here are some small scripts:

tailwind_watch

npx tailwindcss -i ./styles/input.css -o ./styles/output.css --watch

tailwind_build

npx tailwindcss -i ./styles/input.css -o ./styles/output.css --build

tailwind_minify

npx tailwindcss -i ./styles/input.css -o ./styles/output.css --minify

Make scripts exectuable with chmod +x scriptname.

Calling the scripts:

./tailwind_watch
./tailwind_build
./tailwind_minify

The array_merge function produces unexpected results on a PHP 8 server, as compared to a PHP 7 server.

$output = array_merge($array1, $array2);

In PHP 8, if array2 is empty, the $output array is also empty.

In PHP 7, if array2 is empty, the $output array is $array1.

XAMPP is an open-source bundle of Apache + MariaDB + PHP + Perl and most popular PHP development environment. It bundles different versions of PHP and allows for local development of Apache/PHP server setups.

After installing a PHP 8 version of XAMPP - and renaming the XAMPP folders - I got the following error message:

Apparently, XAMPP does not like being renamed.

Workaround: Rename the version you want to work with to XAMPP, then the manager-osx will start.
