Run shell script from javascript

[NAJ]

Hi all,

anybody know if it's possible to run a shell command from within javascript? The ultimate goal is to place a javascript in the Scripts Menu of Photoshop that would run an applescript. I know you're going to say why not just do the script in javascript but the script I'm trying to execute does a lot more outside of PhotoShop. As an applescript is not accessible from the Scripts Menu I wandered if I could get a javascript to execute the applescript. The reason that Shell script is mentioned in the subject is because I can execute an applescript using a simple shell command of : osacript /path/to/the/script/file.scpt So if JavaScript can run the shell command I should be able to get it to work.

Thanks for looking,

Nik

I moved you're post to Photoshop Scripting forum.

app.system("osacript /path/to/the/script/file.scpt");

However, this is not a synchronous call. Depending on your apple script, it may continue to run after the function (app.system()) returns.

Many thanks for the response.

I tried running this command from within ExtendScript:

app.system("osascript '/Applications/Adobe Photoshop CS5/Presets/Scripts/Save_and_Join_v1.scpt'");

but it just causes PhotoShop to hang.

If I run this command in Terminal it works fine:

osascript '/Applications/Adobe Photoshop CS5/Presets/Scripts/Save_and_Join_v1.scpt'

Any ideas why this would happen?

Thanks,

Nik

Not sure why you are seeing the error. I suggest starting off with simpler .scpts and build up to see if that helps isolate the problem.

My script is only saving the file to a new location. The only thing I can think that maybe causing the error is because my applescript displays a dialog before saving and this isn't appearing. I wander if the user interaction is a problem.

Thanks,

I wander if the user interaction is a problem.

That would be a good guess. See if you can get around that AS dialog.

I have managed to get my script to work. I had to save the applescript as an application then get the javascript to just open it like so:

app.system("open '/Applications/Adobe Photoshop CS5/Presets/Scripts/Save_and_Join_v1.app'")

Thanks for the help,

Nik

Shouldn't it be: app.system("osacript -e /path/to/the/script/file.scpt");

I am seeing below error while ruuning this in Debugger

TypeError: app.system is not a function

[Kukurykus]

Don't use app.system() in Debuger.

[Syamala]

I am trying to do the same , when i am trying to call app.system("open '/Applications/example.app'")

I see below error TypeError: app.system is not a function. I want to open application using shell command from javascript

[Kukurykus]

app.system() is extendscript specific command.

[Syamala]

Is there a way to call system calls from javascript?

[Kukurykus]

system()

[Syamala]

ReferenceError: system is not defined 1:Console:Exec, no luck in javascript

[Kukurykus]

Did you put any content to system(), and ran .jsx with Photoshop?

Do you happen to know the equivalent to this line on OSX.

app.system( 'osascript -e \'tell application "System Events" to key code "124"\'' ); 

 This line below tell the OS to press arrow key. Im looking for this for Windows however im really new to Windows so dont know shell or cmd i can use. 

[Kukurykus]

Do it with vbscript.
