The run ��� mac os x

The run ��� mac os x

By Rob LeFebvre • 6:00 am, November 7, 2012

Ever want to run multiple copies of a program at the same time? Yeah, me neither. But when I ran across this tip, I thought, hey, that’d be pretty cool. I could run two copies of Calculator on the same Mac. At the same time! Or even something like NetNewsWire, running one instance of the app that uses one Google account, and a second instance of the app that uses a different account. Pretty neat, right? But how? It sounds complicated. The word “instance” sounds complicated.

Turns out, it’s really fairly simple. Let’s try it out.

Launch the AppleScript Editor, first of all. I know! AppleScript can be scary. But trust me, this is cool. You’ll find this in the Utilities folder, which is nestled in your Applications folder. Once it’s launched, you’ll see an Untitled editing window. Copy and paste the following into the empty window:

do shell script «open -n «

Next, make the Finder active by clicking on the little happy face icon on the left of your Dock. Open the Applications folder, and choose an app you want to run two (or more!) instances of. I chose NetNewsWire. Click and drag that app over to the empty AppleScript editor window, and drop it just to the left of that final quotation mark in the line above, giving you:

do shell script «open -n /Applications/NetNewsWire.app»

Now, click on the Scripts menu at the top of your screen, and choose Compile. Or just hit Command-K on your keyboard. Then choose Save from the File menu, and be sure to change the file type to “Application.” Save it on the Desktop for now.

Once you’ve saved the new app, you can double click on it over and over to launch multiple instances of the app you just chose. Some apps won’t work, like iTunes, but many will. Give it a try and let us know how it goes in the comments below.

Running script upon login mac [closed]

Want to improve this question? Update the question so it’s on-topic for Stack Overflow.

Closed 8 years ago .

I am wondering if anyone is able to help me out with getting a .sh file to run when I log in to my account on my computer. I am running Mac OS X 10.6.7.

I have a file «Example.sh» that I want to run when I log onto my computer. I do not have a problem running it when I am already logged in, but I want this to run automatically.

• start Automator.app
• select Application
• click Show library in the toolbar (if hidden)
• add Run shell script (from the Actions/Utilities )
• copy & paste your script into the window
• test it

save somewhere (for example you can make an Applications folder in your HOME, you will get an your_name.app )

go to System Preferences -> Accounts -> Login items

EDIT:

I’ve recently earned a «Good answer» badge for this answer. While my solution is simple and working, the cleanest way to run any program or shell script at login time is described in @trisweb’s answer, unless, you want interactivity.

With automator solution you can do things like next:

so, asking to run a script or quit the app, asking passwords, running other automator workflows at login time, conditionally run applications at login time and so on.

tl;dr: use OSX’s native process launcher and manager, launchd .

To do so, make a launchctl daemon. You’ll have full control over all aspects of the script. You can run once or keep alive as a daemon. In most cases, this is the way to go.

1. Create a .plist file according to the instructions in the Apple Dev docs here or more detail below.
2. Place in

/Library/LaunchAgents

Log in (or run manually via launchctl load [filename.plist] )

For more on launchd , the wikipedia article is quite good and describes the system and its advantages over other older systems.

Here’s the specific plist file to run a script at login.

Updated 2017/09/25 for OSX El Capitan and newer (credit to José Messias Jr):

Replace the after the Program key with your desired command (note that any script referenced by that command must be executable: chmod a+x /path/to/executable/script.sh to ensure it is for all users).

Run launchctl load

/Library/LaunchAgents/com.user.loginscript.plist and log out/in to test (or to test directly, run launchctl start com.user.loginscript )

Tail /var/log/system.log for error messages.

The key is that this is a User-specific launchd entry, so it will be run on login for the given user. System-specific launch daemons (placed in /Library/LaunchDaemons ) are run on boot.

If you want a script to run on login for all users, I believe LoginHook is your only option, and that’s probably the reason it exists.

How can I get a script to run every day on Mac OS X?

10 Answers 10

For reference, all 3 options would work. The iCal option however has more limitations than the others.

(There are GUIs for editing cron and launchd as mentioned in other answers)

Cron is the most straight forward and well known and there are many tutorials available. The Coles Notes is to add the last line from below to your crontab (either by editing /etc/crontab or using crontab on the command line):

In Mac OS X, cron has actually been replaced by launchd but launchd is backwards compatible with cron meaning you can still use cron but it’s actually launchd doing all the work.

If you want to use launchd you’ll want to check out other questions here on Super User as well: (eg. How do I run a launchd command as root?) as to where you want to save your configuration file (the plist file) as when it runs depends on what directory it is stored in and how it’s loaded (eg. whether you used sudo or not) — similar to cron.

A sample run daily launchd plist (be sure the file and and the label are the same — minus the plist for the label) follows — this script is run everyday at 3 minutes past midnight:

It’s also worth noting that launchd tasks if they were scheduled for when the computer is asleep or off, they will run when the computer becomes available again (turning it on or waking it up) — though only once no matter how many days it may have been. Edit: I just was at an Apple document that said that if the machine is off, then you will lose any launch events during that time, (your script will not launch on startup), (sleep does launch script on waking up)

Another option is to use «at» (check manual page with «man at»). The script can reschedule itself with e.g.:

(use «+ 10 minutes» instead of «tomorrow» to run it every 10 minutes; to stop scheduling, just do «at -l» to list the scheduled job ids and then «at -r id» to remove the job)

You may have to start the corresponding daemon (atrun) first with (see https://superuser.com/a/43680):

Advantages: quick fix, no sudo/root access needed, easy to do complicated schedule patterns Disadvantage: not standard scheduling method for OS X (which is launchd)
