Apple TV, Apple Music, and Apple Podcasts content can be synced using iCloud across all of your devices, but for those who prefer using cables and syncing directly from a Mac, that functionality is still available from each of the three apps.

Sidecar is designed to let you use an iPad as a secondary display with your Mac. You can hold your mouse over the green button on any Mac app window to get into Sidecar mode with an available iPad, you can access it from the System Preferences app, or you can access it from the AirPlay interface on the Mac.

Sidecar lets you either mirror your display or extend it to the iPad, and because the Apple Pencil works in Sidecar mode, you can use the Apple Pencil as a mouse or as a drawing implement in apps like Photoshop.

The Find My app is designed to make it easy to locate your devices and your friends who are sharing their location in a single app. Find My works like the previous Find My iPhone and Find My Friends apps, displaying device and friend locations, but there's a new feature that lets you find a missing Mac even when it doesn't have a WiFi or cellular connection.

The Find My feature works by utilizing crowd-sourced location information delivered through Bluetooth signals. Basically, your devices give off a Bluetooth signal that can be picked up by other nearby iPhones, iPads, and Macs, relaying that signal back to you so you can find your missing device. Find My uses end-to-end encryption to keep your location safe, so it requires at least two Apple devices to work, aka your Mac and an iPhone or other device.

The signal that your Mac gives off is broadcast as a public key, which, when picked up by other people's devices, is encrypted and sent back to you with the location of your device. Only another one of your devices can decrypt that encrypted signal with info from the lost device, keeping your device location secure at all times. Apple in macOS Catalina and iOS 13 redesigned the Photos app, implementing a new Photos tab that's designed to put your best photos front and center so you can relive your memories at a glance. The app lets you view all of your photos like before, but it also has new options for viewing images organized by day, month, and year.

These viewing modes filter out clutter like screenshots, duplicate images, and photos of receipts so you can see your most significant moments without the cruft. In the new Photos tab, muted Live Photos and videos play as you scroll, which has the effect of bringing your photo library to life.

The best of your photos are also shown larger, accompanied by smaller shots, making your photo library more dynamic. The Days view shows the photos you've taken that day, while the Months view presents your photos categorized into events so you can see the best of the month at a glance. The Years view surfaces photos taken around the current date on past years.

Apple highlights titles like location, concert performer, holiday, and more, and under the "All" view, you can zoom in or zoom out to see more or less of your entire photo library at one time. Using the machine learning capabilities of your Mac, the Photos app can recognize who is in your photos and what's happening to highlight moments like birthdays, anniversaries, and trips. There's a new start page in Safari that offers up favorites, frequently visited sites, and Siri suggested content like websites in your browsing history, recently visited sites, bookmarks, content from your reading list, iCloud Tabs, and links you receive in the Messages app.

Safari will now provide weak password warnings when you're signing up for a new account and using a weak, easy to guess password. Safari will tell you that it's a weak password and will offer a stronger replacement password. New tools let you manage folders and subfolders, and there are options for sharing an entire folder. Search is more powerful in the Notes app and can recognize what's in the images inside of your notes to help you find specific text like receipts or bills. Checklists have been improved with options to reorder checklist items, indents added with a swipe , and a feature that lets you reuse a checklist with a click to uncheck all of the items.

A new Block Sender option in Mail lets you block email from a specific person, routing all of the messages from that person into the trash. Noisy email threads can be muted with a new mute option that silences all notifications across all of your Apple devices. Apple now offers an unsubscribe link for email messages from commercial lists above the email header, and clicking it remotes your email address from the mailing list.

The Reminders app was completely rebuilt in iOS 13 and macOS Catalina to make it much more functional and to replicate features found in more robust third-party apps. The new Reminders app features an updated design organized into four sections: Today, Scheduled, All, and Flagged. Reminders are organized into different lists, with customizable colors and icons. Under each reminder entry, you can create additional nested reminders, and multiple lists can be grouped together. When creating a new Reminder, there are options to add attachments, photos, documents, scans, and web links related to a reminder, and you can also include times, dates, locations, flags, and more all at once.

Apple says that when you type longer, more descriptive sentences in the Reminders app, it will automatically understand and provide relevant suggestions to you. Siri intelligence can also bring up suggestions to create a reminder when you make a plan in Messages. QuickTime Player has a picture in picture feature that will let you play a video in a resizable window that's not blocked by other windows, so you can watch it while working on other things.

There's also an improved Movie Inspector pane that shows you more in-depth technical information about the open media file such as video color space, HDR format, bit depth, scale, and aspect ratio. Other new features include timecode support, transparent video support, and the option to create an H. You can also have music come on when a HomeKit sensor detects something like motion, or at a specific time of day. Video feeds are encrypted end-to-end and uploaded to iCloud, which means you alone will see the video footage without the risk of hackers accessing it.

As with existing home security cameras, HomeKit Secure Video will provide notifications if activity is detected so you can review the recordings. Clicking into your Apple Account presents several new options including an Overview mode, where you can make sure your account is signed in and that features are working.

This is the default completion of Bash. However, programmable completion goes much beyond that, because it allows command-specific completions that can depend on the context. Imagine, for example, typing cmd -[tab][tab] , and then seeing a list of all options that are applicable to this command. Programmable completion allows to do that. Programmable completion logic is defined by the creators of commands in completion specifications, typically in the form of completion scripts.

These completion scripts have to be sourced in your shell to enable the completion functionality for a command. The problem is that the programmable completion features of Bash have been extended since version 3.

Identifying Your Operating System (OS)

By upgrading to a newer version of Bash, you become able to use these completion scripts, which can be extremely useful.
