AppleScript Question

Pass in variable from shell script to applescript

I've got a shell script that I call that uses

osascript
, and that
osascript
calls a shell script and passes in a variable that I've set in the original shell script. I don't know how to pass that variable in from the applescript to shell script.

How can I pass in a variable from shell script to applescript to shell script...?

Let me know if I don't make sense.

i=0
for line in $(system_profiler SPUSBDataType | sed -n -e '/iPad/,/Serial/p' -e '/iPhone/,/Serial/p' | grep "Serial Number:" | awk -F ": " '{print $2}'); do
UDID=${line}
echo $UDID
#i=$(($i+1))
sleep 1


osascript -e 'tell application "Terminal" to activate' \
-e 'tell application "System Events" to tell process "Terminal" to keystroke "t" using command down' \
-e 'tell application "Terminal" to do script "cd '$current_dir'" in selected tab of the front window' \
-e 'tell application "Terminal" to do script "./script.sh ip_address '${#UDID}' &" in selected tab of the front window'

done

Answer

Shell variables doesn't expanding inside single quotes. When you to want pass a shell variable to osascript you need to use double "" quotes. The problem is, than you must escape double quotes needed inside the osascript, like:

the script

say "Hello" using "Alex"

you need escape quotes

text="Hello"
osascript -e "say \"$text\" using \"Alex\""

This not very readable, therefore it much better to use the bash's heredoc feature, like

text="Hello world"
osascript <<EOF
say "$text" using "Alex"
EOF

And you can write multiline script inside for a free, it is much better than using multiple -e args...
