I don't have much experience with shell scripting and don't fully understand passing arguments to if else statements. I want to check the state of an auto proxy, i.e. whether it is enabled or disabled. if it is enabled(has an url) i want to turn it off and vice versa.
so far i have:
#!/bin/bash
if [[networksetup -getautoproxyurl "Wi-Fi"] = "https://mediahint.com/default.pac"] then
networksetup -setautoproxystate "Wi-Fi" off
osascript -e 'tell application "Terminal" to quit'
else
networksetup -setautoproxyurl "Wi-Fi" https://mediahint.com/default.pac
osascript -e 'tell application "Terminal" to quit'
fi
it's just the argument of the if statement i'm not sure on.
the statements work fine i have checked in another script.
Syntactically, all is ok, except the fiest line.
You must write:
if [ `networksetup -getautoproxyurl "Wi-Fi"` = "https://mediahint.com/default.pac" ]; then
Note:
backticks ``, that mean command subsitution;
; before then;
space before ] and after [.

I'm trying to get applescript to interact with the bash for loop that is a part of my code to keep from having to list each host manually and execute individual tell/end tell blocks for each host found in the hosts2.txt file.
The purpose of the script is to open a new terminal tab on my Mac and automatically launch "screen -r $HOST" in each new terminal until the end of the list of hosts in the hosts2.txt document. Each host is listed on its own line.
I've tried an all inclusive for loop, without the applescript "repeat 2 times" "end repeat" code that is shown below. It is repeating 2 times because there are only 2 hosts listed in the text document for testing purposes. Each time I have error output.
#!/bin/bash
for HOST in `cat ~/bin/hosts2.txt`
do echo $HOST
osascript -e 'repeat 2 times
tell application "Terminal" activate
tell application "System Events" to keystroke "t" using [command down]
tell application "Terminal" to activate
set host to $HOST
tell application "Terminal"
do shell script "screen -r " & host in front window
end tell
end repeat'
done
What I expect to happen is for the code the execute opening new terminal tabs with screen -r for each host. Error output is below this line.
dev
44:52: syntax error: Expected end of line but found command name. (-2741)
pulsar
44:52: syntax error: Expected end of line but found command name. (-2741)
There are a few issues with your script: some that stop it from working entirely; some that get it to do the wrong thing; and some that needn't have been there in the first place. There are couple of other answers that address some points, but neither of them appeared to test the script because there's a lot they don't address.
...for each host found in the hosts2.txt file...
...Each host is listed on its own line.
Then this line:
for HOST in `cat ~/bin/hosts2.txt`
is not what you want. That will create an array out of individual words, not lines in the file. You want to use the read command, that reads a file line-by-line. You can structure a loop in this manner:
while read -r HOST; do
.
.
.
done < ~/bin/hosts2.txt
As #entraz has already pointed out, your use of single quotes will stop shell variables from being expanding within your osascript.
Then there is the AppleScript itself.
I'm unclear why you included a repeat loop.
The purpose of the script is to open a new terminal tab on my Mac and automatically launch "screen -r $HOST" in each new terminal until the end of the list of hosts in the hosts2.txt document. Each host is listed on its own line.
It is repeating 2 times because there are only 2 hosts listed in the text document
This makes no sense, given that you implemented a bash loop in order to read the lines into the $HOST variable. Granted, you were reading words, not lines, but the AppleScript repeat is a head-scratcher. Bin it.
Then you have this:
tell application "Terminal" activate
tell application "System Events" to keystroke "t" using [command down]
tell application "Terminal" to activate
That's approximately infinity times the number you need to tell Terminal to activate.
This line:
set host to $HOST
will throw an error for two reasons: firstly, host is taken as an existing name of a property in AppleScript's standard additions, so you can't go and set it to a new value; secondly, there are no quotes around $HOST, so it's not going to be recognised as a string. But, this is just for your learning, as we're actually going to get rid of that line completely.
Finally:
tell application "Terminal"
do shell script "screen -r " & host in front window
end tell
is wrong. do shell script is not a Terminal command. It's a command belonging to AppleScript's standard additions. Therefore, if the rest of your code worked, and it got to this command, Terminal would execute nothing. Instead, the shell scripts would run in the background without an actual shell, so that's not much good to you.
The command you're after is do script.
Sadly, it does appear that, in High Sierra at least, the AppleScript commands to make new tabs and windows in Terminal no longer work, so I can see why you resorted to System Events to create a tab in the way that you have. Thankfully, that's not necessary, and nor are your multiple activate commands: do script will automatically run Terminal and execute a script in a new tab by default.
Therefore, the only AppleScript command you need is this:
tell application "Terminal" to do script "screen -r $HOST"
The Final Script
Putting this all together, here is the final hybrid script:
while read -r HOST; do
echo "$HOST"
osascript -e "tell application \"Terminal\" to do script \"screen -r $HOST\""
done < ~/bin/hosts2.txt
Alternatively
If you wanted to take the loop from bash and put it in AppleScript instead, you can do so like this, for which I'll use a heredoc (<<) to simplify the use of quotes and aid readability:
osascript <<OSA
property home : system attribute "HOME"
property file : POSIX file (home & "/bin/hosts2.txt")
set hosts to read my file using delimiter {return, linefeed}
repeat with host in hosts
tell application "Terminal" to do script ("screen -r " & host)
end repeat
OSA
You have a typo in your code.
The line tell application "Terminal" activate should be tell application "Terminal" to activate.
Variable expansion also doesn't work in single quotes in bash (single quotes means everything is interpreted literally), so the line set host to $HOST within the single quotes won't work.
Try this:
#!/bin/bash
for HOST in `cat ~/bin/hosts2.txt`
do echo $HOST
osascript -e "repeat 2 times
tell application \"Terminal\" to activate
tell application \"System Events\" to keystroke \"t\" using [command down]
tell application \"Terminal\" to activate
set host to \"$HOST\"
tell application \"Terminal\"
do shell script \"screen -r \" & host in front window
end tell
end repeat"
done
Edit: I think there's actually another problem: when setting a variable to a string in applescript, the string needs to be enclosed in quotes. So set host to $HOST causes an error because it interprets the value of $HOST ("pulsar" or "dev") as a command that it's unable to find/execute; it needs to be set host to \"$HOST\" instead. I've changed it above.
You might find a here-doc to be readable and easy to work with. Also, use a while-read loop to iterate over the lines of a file (ref: http://mywiki.wooledge.org/BashFAQ/001)
while read -r host; do
echo "$host"
osabody=$(cat << END_OSA
repeat 2 times
tell application "Terminal" to activate
tell application "System Events" to keystroke "t" using [command down]
tell application "Terminal" to activate
set host to "$host"
tell application "Terminal"
do shell script "screen -r " & host in front window
end tell
end repeat
END_OSA
)
osascript -e "$osabody"
done < ~/bin/hosts2.txt
The ending parenthesis of the $(cat ... command substitution has to be on a separate line because the terminating word of the heredoc must be the only characters on that line.
I'd like to run a script to close all apps currently open in my doc. Figured out how to do with with the following script, where APPLICATIONNAME is the name of the app in the dock currently open
osascript -e 'quit app "APPLICATIONNAME"'
Any ideas on how to expand this command to encompass all apps open inside the doc?
Ideally we'd avoid using a killall flavor of script. As force closing running apps in bulk will pose risks in some circumstances
Firstly there is no terse solution to achieve this using osascript as described in your question. osascript by itself simply doesn't provide the options/arguments necessary to fulfil the logic of your requirement.
However, the following bash shell script (.sh) avoids using killall and will prompt the user to save any unsaved changes to document(s) before closing/quitting the application. (This is very similar to how the user is prompted to save any unsaved changes when shutting down the computer):
close-apps.sh
#!/bin/bash
# Creates a comma-separated String of open applications and assign it to the APPS variable.
APPS=$(osascript -e 'tell application "System Events" to get name of (processes where background only is false)')
# Convert the comma-separated String of open applications to an Array using IFS.
# http://stackoverflow.com/questions/10586153/split-string-into-an-array-in-bash
IFS=',' read -r -a myAppsArray <<< "$APPS"
# Loop through each item in the 'myAppsArray' Array.
for myApp in "${myAppsArray[#]}"
do
# Remove space character from the start of the Array item
appName=$(echo "$myApp" | sed 's/^ *//g')
# Avoid closing the "Finder" and your CLI tool.
# Note: you may need to change "iTerm" to "Terminal"
if [[ ! "$appName" == "Finder" && ! "$appName" == "iTerm" ]]; then
# quit the application
osascript -e 'quit app "'"$appName"'"'
fi
done
Note: In the following line of code we avoid closing the Finder and the CLI tool that the command will be run via. You will probably need to change "iTerm" to "Terminal", or to whatever the name of your CLI tool is:
if [[ ! "$appName" == "Finder" && ! "$appName" == "iTerm" ]]; then
Making close-apps.sh executable
As explained in this answer you will need to make the close-apps.sh executable before it can be run. To do this enter the following via your CLI:
$ chmod +x /path/to/close-apps.sh
(The /path/to/close-apps.sh part should be replaced with your path according to where the script is saved)
Running close-apps.sh via the CLI.
You run the shell script by entering the following into the CLI:
$ /path/to/close-apps.sh
(Again, the /path/to/close-apps.sh part should be replaced with your path according to where the script is saved)
Running close-apps.sh via an Applescript.
The shell script can also be executed via an AppleScript application simply by double-clicking instead of entering a command via the CLI.
To do this you'll need to:
Open the AppleScript Editor application, which can be found inside the Applications/Utilities/ folder.
Enter the following code:
on run
do shell script "/path/to/close-apps.sh"
quit
end run
(Again, the /path/to/close-apps.sh part should be replaced with your path according to where the .sh script is saved)
Save the Applescript and chose File Format: Application via the save dialog. Let's call it closeApps.app.
Finally, the following line of code in the close-apps.sh script should be changed from this:
if [[ ! "$appName" == "Finder" && ! "$appName" == "iTerm" ]]; then
... to this:
if [[ ! "$appName" == "Finder" && ! "$appName" == "closeApps" ]]; then
Note The filename of the Applescript (closeApps) replaces iTerm (or Terminal).
To close all applications open in the dock you simply double click the closeApps application icon.
Try this
tell application "System Events"
set appList to the name of every process whose background only is false
end tell
repeat with theApp in appList
try
tell application theApp to quit
end try
end repeat
I have a bash script that contains a small amount of Apple Script as well. This script is for printer management. We have some MFD printers that require mapping by IP at our organization, and then for all other printers we use a print server/queue name.
If the script only includes a single conditional, mapping these MFD's with the method we're using works perfectly. For example:
INPUT=/Users/Shared/File.csv
OLDIFS=$IFS
IFS=","
while read Asset PQN IP Model Manu
do
if [ "$Manu" == "Canon" ]; then
$tagnum = $Asset
sudo mv -n /Users/Shared/Drivers/* /Library/Printers/PPDs/Contents/Resources
sudo mv -n /Users/Shared/Canon /Library/Printers/
lpadmin -E -p "$PQN" -v "lpd://$IP" -P "/Users/Shared/PPD/$Asset.ppd" -o printer-is-shared=false
cupsenable "$PQN"
cupsaccept "$PQN"
if [ $? -eq 0 ]; then
osascript -e 'tell app "System Events" to display dialog "Printer '$PQN' Added!"'
else
osascript -e 'tell app "System Events" to display dialog "Error on Manu - The printer '$Asset' could not map correctly. Please call X at x." with text buttons {"OK"}'
fi
else
do stuff here
fi
done < $INPUT
If I were to remove the else statement here and just use the single if statement, it works no problem. However, if I add the else statement, it always, without fail goes to whatever the else statement is. This holds true if I turn it into an if, elif, else statement as well. I change the conditional not at all, but if it's anything but a solitary conditional statement then it always ignores the statement (even though it's true) and goes to the else or last argument.
Is it something to do with being in the while loop? I can't wrap my head around the logic. Ideally once we figure out how to make it so it doesn't always go to the last conditional option, we can add another argument so that we can map the non-MFD printers using print server/queue name, which we have working fine as well in another script. Currently that's not possible as I can't figure out how to do more than one argument without this issue occurring.
#/bin/bash
corr="apple"
echo $corr
osascript -e 'tell application "Messages" to send "Did you mean "'"$corr"'" " to buddy "A"'
Error:
51:57: syntax error: A identifier can’t go after this “"”. (-2740)
If I just pass
osascript -e 'tell application "Messages" to send "Did you mean $corr " to buddy "A"'
the message comes like "Did you mean $corr"
I have tried everything mentioned at Pass in variable from shell script to applescript
There is a very good explanation with decent examples at the very end of here.
Based on that, I was able to make this work (using TextEdit, not Messages):
#!/bin/sh
rightNow=$(date +"%m_%d%B%Y")
osascript -e 'on run {rightNow}' -e 'tell application "TextEdit" to make new document with properties{name: "Date003.txt", text:rightNow}' -e 'end run' $rightNow
I also found that I had to be VERY careful about the single and double quotes. For some reason, my keyboard kept replacing the plain quotes with curled quotes. Annoying.
I have the following script:
i=1;
while [ $i -lt 51 ]
do
osascript -e 'tell app "Terminal"
do script "php $i.php"
end tell' &
i=$[$i+1]
done
I am trying to open a terminal window that executes 1 of 50 php scripts. However, I cannot get the value of $1 to print correctly. In fact, In each terminal its just blank. Each scripted is named 1.php to 50.php - how do I get the value of i to print properly to render the correct file name?
Note, I have been applescripting about an hour. Very open to suggestions to a better script. What I am trying to do is run 50 simultaneous PHP scripts in 50 separate windows simultaneously. Thanks!
It's just a quoting problem - change:
osascript -e 'tell app "Terminal"
do script "php $i.php"
end tell'
to:
osascript -e "tell app \"Terminal\"
do script \"php $i.php\"
end tell"
