Hi all,
does anybody knows why inside my applscript a script won't run properly while it will if called from the terminal?
one example
do shell script "directory/myscript.sh"
will not work, while
tell application "Terminal"
activate
do script "directory/myscript.sh"
end tell
will work perfectly?
when you use do shell script you cannot depend on having any particular working directory set, or having any of the environment variables available that you expect in a terminal session. specififying full (rather than relative) paths to any script or utility you use solves most problems, but without seeing the script...
As twtwtw says, your environment from withing an Applescript (or Automator workflow) is NOT going to be the same as when running a script from the termianl
You might try running a script that contans:
( echo "your current working directory"
pwd
echo "your user and group IDs"
id -a
echo "your environment variables"
printenv
echo "your args"
for v; do echo "$v"; done
) >/tmp/your_applescript_environment.txt
then run your script using a FULL PATH to the script and go look at the file generated in /tmp to see what your environment looks like. If you have dependencies on any environemnt variables NOT present in the .txt file you will have to modify your script so it does not need them or it gets the information from another source.
thanks a lot guys, you're saving me, because I'm in a *real* hurry...
can you help me launch this from an applescript?

A quick pass over the script does not show any specific environment dependencies
So I would like to know what
do shell script "directory/myscript.sh"
really looks like. I'm guessing twtwtw would as well.
here it is... (btw: thanks guys!)
do shell script "/Users/test.app/Contents/.script_dog/watchdog.sh /dev/null 2'>'&1 &"
Ok, a couple of things...
are you dunning this from within test.app? If so, then you want to use the path to resource command that you'll find in Standard Addition osax.
your shell command looks weird to me. it ought to be:
do shell script "/Users/test.app/Contents/.script_dog/watchdog.sh &> /dev/null &"
no?
There are a couple of questionable things in the script. For instance, you have a routine to catch keyboard input, but running from AppleScript it won't have a console and no possibility of keyboard input, so for all you know it's reading random noise. Also, I would want to test that the ps command is doing the same thing called from applescript that it does from terminal. Sometimes utilities like that present different output formats when they are not writing to a terminal.
thanks twtwtw,
i tried to put it on the desktop, to be sure the problem was it being inside an app.
than I put the do shell script as you suggested... unfortunatley without results...
again, it worked if launched from the terminal, BUT it didn't if launched from the applescript.
If it may help the script is looking for an application not responding, if so it kills it.
Works on command line, doesn't if launched from applescript... very strange, isn't it?
Any other way to launch it?
ok. if I can't solve this I'd rather be ok with this other thing:
how do i call an applescript from here?
it was supposed to do so, but it is actually not working...
this is the line
***
HUNG_DETECTION_EXTERNAL_SCRIPT_CALLBACK=/hung.app
***
where "hung.app" is the applescript application in the same folder of this sh
but it is actually not launching... any idea about this?
Are you seeing any errors produced in Console.app? you may have to do some old school debugging (throw in log statements to figure out where the script is failing).
running shell from applescript
