This is a cheat sheet for how to perform various actions to ZSH, which can be tricky to find on the web as the syntax is not intuitive and it is generally not very well-documented.
| Description | Syntax |
|---|---|
| Get the length of a string | ${#VARNAME} |
| Get a single character | ${VARNAME[index]} |
I need very often to modify filenames or replace/delete their parts across huge number of files. I was using sed command for these purposes but recently I have found out that all these tasks can be easily done directly in bash (or zsh) because both of them support so called string manipulation operations.
Define some example string:
$ file=some_file_name.txt

Below are a list of System Preference pane URLs and paths that can be accessed with scripting to assist users with enabling macOS security settings without having to walk them through launching System Preferences, finding panes, and scrolling to settings. Not all panes have an accessible anchor and some are OS specific.
To find the Pane ID of a specific pane, open the System Preferences app and select the desired Preference Pane. With the pane selected, open the ScriptEditor.app and run the following script to copy the current Pane ID to your clipboard and display any available anchors:
tell application "System Preferences"
set CurrentPane to the id of the current pane
set the clipboard to CurrentPane
