![]() ![]() In this case, there's just one entry in the list, which is itself another list, this time of the dictionary type. You can see that the value needed to specify a scheduled job is actually an array of values, which is like a list. Label cleanme.job ProgramArguments /usr/bin/osascript /Users/michaelbyrne/cleaner.scpt RunAtLoad StartCalendarInterval Hour 16 Minute 00 It's scheduled to run every day at 4:00 PM. Here is the complete plist file for my job. ![]() The label is of type key while the value is of type string. One such pair might look like this, where "label" is the name I've given the scheduled job (which is a different name than that of the script itself). If you remember, a plist file contains a list of key-value pairs. In mine I already have plists for Adobe, Spotify, and Google.Ī plist file is actually an XML file, which is a file containing identifiers enclosed by tags specifying the types/meanings of those identifiers. You probably already have a couple of plist files in there for installed applications that automatically start when you login to your computer. This is where we'll put the plist files launchd needs to run scheduled jobs. (AppleScript is a Open Scripting Architecture language and is thus interpreted by an OSA language interpreter, osascript-but really don't worry about it.) Likewise, if I had a Python script, I would need to run it with the "python" command.īy default, you should (on a Mac) have a directory called LaunchAgents in your user Library directory ($HOME/Library/LaunchAgents). If I'm in Bash or another shell (read: command line-based program), I'll need to specify that my AppleScript script is to be run with the AppleScript interpreter. If I have a Bash script with a ".sh" file extension and I'm currently operating within a Bash shell session (just type "Bash" into an OSX Terminal window), I can run it just by entering the filename prefixed with its filesystem path and hitting enter. It's ultimately up to us to tell the computer how they should be interpreted. We can run the above script (which I called "cleaner.scpt") from the Bash shell with the command osascript cleaner.scpt.Īll of these script files, by the way, are just text files and can be edited in and saved from any old text editor. Set timeoutInSeconds to 60 set abortOnTimeout to true tell application (path to frontmost application as text) try set dialogResult to display dialog "Do you want to clean downloads folder?" default button 2 giving up after timeoutInSeconds on error number -128 return end try end tell if gave up of dialogResult and abortOnTimeout then return end if do shell script "/Users/michaelbyrne/cleanup.sh"īasically, if the user clicks cancel or doesn't respond within a set amount of time, the dialog will close and the job will not run. Fortunately, we can solve this digital clutter problem with automation. ![]() I need these photos for like five minutes after I actually download them, but they wind up sitting around and accumulating. For example, in my day to day work for Motherboard, I download loads of image files, and, after a while, I wind up with a downloads folder that's clogged with screengrabs, Shutterstock photos, public domain photos, and so on. For me, it would be useful to have a sort of system janitor that comes around to certain file directories and trashes certain sorts of files. Here, let's automate something fairly simple. This will be most useful to you with shell scripts, which are just listings of shell commands (command line commands) that are packaged into a single file and do (automate, perhaps) something useful. And anything you can open on the command line, you can launch with launchd. Any program you can open with the click of a mouse you can open using the command line ( open -a program_name).
