If the token exists, we’re live, otherwise we’re ready to start recording.Ī really simple way to keep track of state with command line scripts is to put things in the filesystem, and doing this with process IDs is a common practice called pid files. Because the recording command is being run as a background job, it’s necessary to keep track of the process ID so it can be interrupted later, so it can serve as a token to represent this state. ![]() If it’s recording and it’s stopped, stop and convert the recording. If the script is recording and it’s cancelled, stop and clean up. The overall flow is something like: if the script is not recording, start recording. Part of the problem is that there’s some state that needs to be tracked, particularly whether the script is currently recording something. How would a shell script be used like a toggle button? So now we can record the iOS simulator in the background, and it’s possible to stop the recording when we’re ready, but how do we use this script? Thinking about a typical workflow, we’d probably want to have some sort of record button, maybe in the menu bar, or a global hotkey that could be pressed to start and stop recording. This time, before 1000 seconds is up, run kill -INT process_id (put the number in place of process_id) and see what happens. Note the process ID that’s printed out, it’s the second number. Try running sleep 1000 & wait echo “done” like before. Maybe you’ve used the kill command to force-quit a command line tool or daemon, and it uses the same mechanism. So if it’s possible to wait for the recording to finish, how do we send the background job a ctrl+c as if it were still in the foreground? Well, what does ctrl+c actually do? Your terminal is sending a POSIX signal to the command, in particular a SIGINT, and this can also be done programmatically. See what happens when you run sleep 10 & echo “done” and then try it with wait: sleep 10 & wait echo “done”. Your shell will print the job number and process ID of the background job. (Sounds almost too simple when I write it down like that…) A command can be set to run in the background with a trailing ampersand. One way to wait for a command to finish is by running it in the background and then using the wait command. The outer script would need to wait for simctl to finish its work before converting the video to a GIF and doing cleanup. It wasn’t immediately clear how to use this command from within another script. If you try running xcrun simctl io booted recordVideo -type=mp4 recording.mp4 yourself you’ll notice that it starts recording and expects you to type ctrl+c in the terminal in order to stop. ![]() Maybe it would be possible to script this process with simctl? One of the things I would record most often with Jeff was a demo of a new feature I’d worked on to put in a GitHub PR. ![]() Searching for simctl will pull up some good guides to all of the things you can do with this command, but the one that caught my eye was being able to record a video of the screen. The new iOS Simulator in Xcode 9 has some additional commands you can run to control it from the command line. I experimented with another tool too, though, that I wanted to share. I’ve been using Monosnap in its place, pointed at an S3 bucket and subdomain because I had them available. Hope this information is helpful for you.We recently sunset open-sourced Jeff, which for years was our team’s go-to method for making GIF screen recordings and sharing them in Slack, Trello, GitHub or anywhere else. You can also refer to some other tools like: Snagit is a paid tool, however a free trial allows you to get familiar with its functionality and see if it’s right for you. With the help of Snagit, we can capture screen content with just a click, customize with effects and markups and share via many separate formats. Snagit provides a full package of professional tools that allow you to capture and record your PC screen. We are using Snagit from last 7 years to record defects. Sometimes, describing the exact steps in video is so important when a screenshot is not capable enough to capture that particular moment when defect occurs. In highly professional software testing company, there is an inventory of video capturing tools that can help their engineers to showcase defect in an effective way. This is an important topic to discuss as we all came across some specific areas while testing an application which needs to be highlighted using a video. ![]()
