Increase timeout when prompting using osascript from bash script - bash

I'm working on some bash scripting for use in JAMF in my environment. My scripting skills include: googling other peoples scripts, clipping out pieces of those and pasting them into my own script. Then eating the paste. I'm having a bit of a bizarre issue with a piece of AppleScript that runs within a bash script. Original script follows:
#!/bin/sh
# Remove pre-existing settings
rm -rfv /var/db/scrubbed/hostName
rm -rfv /var/db/scrubbed/imageTech
rm -rfv /var/db/scrubbed/adBinding
# Prompt for Hostname of new computer
hostName="$(/usr/bin/osascript -e 'Tell application "System Events" to display dialog "Please enter the Hostname of the new computer:" default answer "" with title "Hostname" with text buttons {"Ok"} default button 1' -e 'text returned of result')"
/bin/echo "Computer hostname set to $hostName"
This code listed works just fine. Pops up my dialog box as expected. Unfortunately the box times out after 60 seconds. This is part of an imaging process so if the tech walks away for a few minutes the script continues and the hostname does not get set. Doing some research I found the with timeout of X command in AppleScript. When I update the first block of code to this:
# Prompt for Hostname of new computer
hostName="$(/usr/bin/osascript -e 'Tell application "System Events" with timeout of 86400 to display dialog "Please enter the Hostname of the new computer:" default answer "" with title "Hostname" with text buttons {"Ok"} default button 1' -e 'text returned of result')"
/bin/echo "Computer hostname set to $hostName"
If it helps, this runs in the actual apple script app
tell application "System Events"
with timeout of 86400 seconds
display dialog "Please enter the hostname of the new computer" default answer "" with title "Hostname" buttons {"Ok"} default button 1
end timeout
end tell
I'm a scrub! Send help!

You need line breaks in the script, just as in the regular AppleScript. You're also missing end timeout, end tell, and the seconds units.
hostName="$(/usr/bin/osascript -e 'tell application "System Events"
with timeout of 86400 seconds
display dialog "Please enter the Hostname of the new computer:" default answer "" with title "Hostname" with text buttons {"Ok"} default button 1
end timeout
end tell' -e 'text returned of result')"

If all you were looking to achieve was getting the actual host name of the computer… this one line of AppleScript code will achieve that for you.
set hostName to host name of (system info)
Otherwise
First, the display dialog command is not handled by System Events. The display dialog command is a Standard Additions command.
Another thing to point out is while using the with timeout clause, the script will continue running after the specified amount of time which was set in the clause. This puts you right back to the initial problem of the script continuing, after the time out, without user input.
The display dialog command has a giving up after option which allows you to set the amount of seconds it will wait until the dialogue will close itself and continue on. You can then add an if… then… clause to stop the script if the display dialog gave up after the specified amount of time.
Here is an example of an AppleScript which may be more suitable to your needs. I added a “Cancel” button giving the user the option to stop the script. I also used 10 seconds for testing purposes rather than 86400…. Which can easily be edited
set enterHostName to display dialog ¬
"Please enter the hostname of the new computer" default answer "" with title ¬
"Hostname" buttons {"Cancel", "Ok"} default button 2 giving up after 10
if gave up of enterHostName then
return
else
set hostName to text returned of enterHostName
end if
Again, the code was only an example. You will have to tweak it to work correctly within Terminal. Or you can save the code as an AppleScript file and use the osascript command in terminal to run the AppleScript file.

How to make osascript display dialog while script continues other commands

So I'm looking at running lets say the following script
#!/bin/bash/
do
echo "Starting script"
osascript -e 'tell app "System Events" to display dialog "Currently script is running, please do not use computer"'
do somecommands
done
I would like the display to stay on the screen while the "do somecommands" is running in the background without terminating that display. Is this possible?
Thanks
You can do it by running the osascript in the background like this:
#!/bin/bash/
echo "Starting script"
osascript -e 'tell app "System Events" to display dialog "Currently script is running, please do not use computer"' &
# do other stuff
However, you will have 2 new problems - how to dismiss the dialog when you are finished and timeouts.
So, if you want to dismiss the dialog later, you will want to know its process id, so you should capture that after you start the background job like this:
osascript -e .... &
pid=$!
# Do some other stuff
# kill the dialog
kill $pid
Unfortunately, that doesn't seem to make the dialog go away - maybe someone else can help with that.
Secondly, if you are doing something time-consuming, the dialog will time out, so you may want to add a timeout like this for, say 100 seconds:
osascript -e 'tell app "System Events" to display dialog "Currently script is running, please do not use computer" giving up after (100)' &
Maybe that is the better way to do it anyway, run a loop and if the timeout expires and you are still busy, redisplay the dialog and if you are finished don't re-display the dialog - then you don't have the problem of how to make it go away at the end.

Apple script open Terminal with ready command

I'm trying to open terminal using apple script with a ready command but without executing it and allowing user to do this just by clicking enter (so I don't want to use tell Terminal to do script)
One of the approaches I used is using keystrokes:
tell application "Terminal" do script "echo Hi!"
keystroke "abc"
end tell
but it doesn't work for me. Any ideas?
I think you want to start Terminal and have a command all lined up ready in the Terminal ready for the user so he/she only has to press "Enter". If so, you can do this:
tell application "Terminal"
activate
delay 1
tell application "System Events"
keystroke "echo hi"
end tell
end tell
Then the user just has to press Enter and the command echo hi will execute.
it is hard to understand what you mean.
You can't for instance have the terminal wait for a user to click its window.
(But you can poll for a keystroke after the terminal window is opened.)
You'd have to use a dialog before your code, in order to make the user enter the terminal consciously.
display dialog "Press ok to enter the terminal" buttons {"Cancel","Enter"} cancel button 1 default button 2
Other than that, the way you'd need to use system events to send keystroke to the Terminal
tell application "System Events"
tell application process "Terminal"
keystroke "abcd"
end tell
end tell
You can poll for a keypress in the do script command to your terminal with this:
read -n 1 -s MYCHAR </dev/tty
This will force the user to press enter from a do script
a=`read`

Setting popup box with osascript and a 10 second delay

I'm looking to setup a popup box for users to see that has a 10 second delay before it exits and the script continues. So far I've got the following.
osascript -e 'tell app "System Events" to display dialog with delay "10" "Running Health Check \r \rPlease allow 30 seconds or more to complete." with title "Health Check"'
I've read that you can use the "delay" function, but I'm having problems getting it inline.
I found my answer, what I needed to do was add in the following...
giving up after 10
So my overall script now looks like this...
osascript -e 'tell app "System Events" to display dialog with delay "10" "Running Health Check \r \rPlease allow 30 seconds or more to complete." giving up after 10 with title "Health Check"'

Script to shutdown mac

I'm trying to automate the shutdown of my mac, I've tried the scheduled shutdown in energy saver and I wanna sleep but these don;t seem to work. VLC player runnign seems to prevent the shutdown. I think I need a script to forcefully shutdown the mac regardless of of what errors may thrown to screen by various programs running.
Thanks
Ok,
This is the applescript code im using to shutdown may mac. I've added it as an iCal event thats runs nightly.
tell application "System Events" to set the visible of every process to true
set white_list to {"Finder"}
try
tell application "Finder"
set process_list to the name of every process whose visible is true
end tell
repeat with i from 1 to (number of items in process_list)
set this_process to item i of the process_list
if this_process is not in white_list then
do shell script "killall \"" & this_process & "\""
end if
end repeat
on error
tell the current application to display dialog "An error has occurred!" & return & "This script will now quit" buttons {"Quit"} default button 1 with icon 0
end try
tell application "System Events"
shut down
end tell
Could you try a simple applescript, which goes something like this...
tell application "System Events"
shut down
end tell
See if it works, and then you can make it run through Automator at certain time, etc.
my solution (somwhat late). Just a bash script with apple in it:
#!/bin/bash
# OK, just shutdown all ... applications after n minutes
sudo shutdown -h +2 &
# Try normal shutdown in the meantime
osascript -e 'tell application "System Events" to shut down'
I also edited the /etc/sudoers (and /private/etc/sudoers) file(s) and added the line:
ALL=NOPASSWD: /sbin/shutdown
Always worked for me for an assured shutdown (knock knock ;-) )
This should do:
do shell script "shutdown" with administrator privileges
If you want to pass the admin password from key chain, with no prompt:
do shell script "shutdown" with administrator privileges password "password here"
But do not store the admin password in clear anywhere. Instead use the keychain access.
Alternatively you could kill all user processes, via:
do shell script "kill -9 -1"
This however would also kill your own Applescript process, preventing it from requesting the shutdown/restart afterwards.
Either way you're playing with fire, when using sudo or kill.
do what linux users do. use a bash script. if u dont know how to create one just go ahead and download ANY bash script u find using your internet search and open it with text edit app and paste the following:
( be careful if many people use the pc , then this method is not recommended, cause they can learn your user login password from inside this script )
#!/bin/bash
echo -n "Enter a number > "
read x
echo [your password] | sudo -S shutdown -h +$x
it will work the same way it works in linux. the terminal will pop up a message and ask you to enter a number. if we choose for exaple 50 , then the pc ( niresh ) or mac will shutdown in 50 minutes.

Sending commands and strings to Terminal.app with Applescript

I want to do something like this:
tell application "Terminal"
activate
do script "ssh user#server.com"
-- // write user's password
-- // write some linux commands to remote server
end tell
For example to log in to the server, enter the password, and then login to mysql and select a DB.
I type that every day and it would be really helpful to bundle it into a script.
Also, is there a reference of what commands, properties, functions, etc. do applications (Terminal, Finder, etc) have available to use within Applescript? thanks!
EDIT: Let me clear this up:
I don't want to do several 'do script' as I tried and doesn't work.
I want to open a Terminal window, and then emulate a human typing in some characters and hitting enter. Could be passwords, could be commands, whatever, just sending chars to the Terminal which happens to be running ssh. I tried keystroke and doesn't seem to work.
First connect to the server and wait for 6 seconds (you can change that) and then execute whatever you need on the remote server using the same tab
tell application "Terminal"
set currentTab to do script ("ssh user#server;")
delay 6
do script ("do something remote") in currentTab
end tell
As EvanK stated each do script line will open a new window however you can run two commands with the same do script by separating them with a semicolon. For example:
tell application "Terminal"
do script "date;time"
end tell
But the limit appears to be two commands.
However, you can append "in window 1" to the do script command (for every do script after the first one) to get the same effect and continue to run as many commands as you need to in the same window:
tell application "Terminal"
do script "date"
do script "time" in window 1
do script "who" in window 1
end tell
Note that I just used the who, date, and time command as an example...replace
with whatever commands you need.
Here's another way, but with the advantage that it launches Terminal, brings it to the front, and creates only one window.
I like this when I want to be neatly presented with the results of my script.
tell application "Terminal"
activate
set shell to do script "echo 1" in window 1
do script "echo 2" in shell
do script "echo 3" in shell
end tell
How about this? There's no need for key codes (at least in Lion, not sure about earlier), and a subroutine simplifies the main script.
The below script will ssh to localhost as user "me", enter password "myPassw0rd" after a 1 second delay, issue ls, delay 2 seconds, and then exit.
tell application "Terminal"
activate
my execCmd("ssh me#localhost", 1)
my execCmd("myPassw0rd", 0)
my execCmd("ls", 2)
my execCmd("exit", 0)
end tell
on execCmd(cmd, pause)
tell application "System Events"
tell application process "Terminal"
set frontmost to true
keystroke cmd
keystroke return
end tell
end tell
delay pause
end execCmd
You don't need to "tell" Terminal to do anything. AppleScript can do shell scripts directly.
set theDir to "~/Desktop/"
do shell script "touch " & theDir &"SomeFile.txt"
or whatever ...
Why don't use expect:
tell application "Terminal"
activate
set currentTab to do script ("expect -c 'spawn ssh user#IP; expect \"*?assword:*\"; send \"MySecretPass
\"; interact'")
end tell
Your question is specifically about how to get Applescript to do what
you want. But, for the particular example described, you might want
to look into 'expect' as a solution.
Kinda related, you might want to look at Shuttle (http://fitztrev.github.io/shuttle/), it's a SSH shortcut menu for OSX.
The last example get errors under 10.6.8 (Build 10K549) caused by the keyword "pause".
Replacing it by the word "wait" makes it work:
tell application "Terminal"
activate
my execCmd("ssh me#localhost", 1)
my execCmd("myPassw0rd", 0)
my execCmd("ls", 2)
my execCmd("exit", 0)
end tell
on execCmd(cmd, wait)
tell application "System Events"
tell application process "Terminal"
set frontmost to true
keystroke cmd
keystroke return
end tell
end tell
delay wait
end execCmd
I could be mistaken, but I think Applescript Terminal integration is a one-shot deal...That is, each do script call is like opening a different terminal window, so I don't think you can interact with it at all.
You could copy over the SSH public keys to prevent the password prompt, then execute all the commands joined together (warning: the following is totally untested):
tell application "Terminal"
activate
do script "ssh jdoe#example.com '/home/jdoe/dosomestuff.sh && /home/jdoe/dosomemorestuff.sh'"
end tell
Alternatively, you could wrap the ssh and subsequent commands in a shell script using Expect, and then call said shell script from your Applescript.
set up passwordless ssh (ssh-keygen, then add the key to ~/.ssh/authorized_keys on the server). Make an entry in ~/.ssh/config (on your desktop), so that when you run ssh mysqlserver, it goes to user#hostname... Or make a shell alias, like gotosql, that expands to ssh user#host -t 'mysql_client ...' to start the mysql client interactively on the server.
Then you probably do need someone else's answer to script the process after that, since I don't know how to set startup commands for mysql.
At least that keeps your ssh password out of the script!
Petruza,
Instead of using keystroke use key code.
The following example should work for you.
tell application "System Events"
tell application process "Terminal"
set frontmost to true
key code {2, 0, 17, 14}
keystroke return
end tell
end tell
The above example will send the characters {d a t e}
to Terminal and then keystroke return will enter and run
the command. Use the above example with whatever key codes you need
and you'll be able to do what you're trying to do.
what about something like this:
tell application "Terminal"
activate
do shell script "sudo dscl localhost -create /Local/Default/Hosts/cc.josmoe.com IPAddress 127.0.0.1"
do shell script "sudo dscl localhost -create /Local/Default/Hosts/cc.josmos2.com IPAddress 127.0.0.1"
end tell
As neat solution, try-
$ open -a /Applications/Utilities/Terminal.app *.py
or
$ open -b com.apple.terminal *.py
For the shell launched, you can go to Preferences > Shell > set it to exit if no error.
That's it.
I built this script. It is in Yosemite and it is bash script using AppleScript to choose a list of users for SSH servers. Basically you define an IP and then the user names.. when the application launches it asks who you want to login in as.. the SSH terminal is launched and logged in prompting a password...
