Pass in variable from shell script to applescript
提问by SirRupertIII
I've got a shell script that I call that uses osascript, and that osascriptcalls 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.
我有一个我称之为使用的 shell 脚本，osascript它osascript调用一个 shell 脚本并传入一个我在原始 shell 脚本中设置的变量。我不知道如何将该变量从applescript 传递到shell 脚本。
How can I pass in a variable from shell script to applescript to shell script...?
如何将变量从shell脚本传递到applescript到shell脚本......？
Let me know if I don't make sense.
如果我没有道理，请告诉我。
i=0
for line in $(system_profiler SPUSBDataType | sed -n -e '/iPad/,/Serial/p' -e '/iPhone/,/Serial/p' | grep "Serial Number:" | awk -F ": " '{print }'); do
UDID=${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

Shell variables doesn't expanding inside single quotes. When you to want pass a shell variable to osascriptyou need to use double ""quotes. The problem is, than you must escape double quotes needed inside the osascript, like:
Shell 变量不会在单引号内扩展。当你想要传递一个 shell 变量时，osascript你需要使用双""引号。问题是，您必须转义 osascript 中所需的双引号，例如：
the script
剧本
say "Hello" using "Alex"
you need escape quotes
你需要转义引号
text="Hello"
osascript -e "say \"$text\" using \"Alex\""
This not very readable, therefore it much better to use the bash's heredocfeature, like
这不是很可读，因此最好使用 bash 的heredoc功能，例如
text="Hello world"
osascript <<EOF
say "$text" using "Alex"
EOF
And you can write multiline script inside for a free, it is much better than using multiple -eargs...
而且你可以免费在里面写多行脚本，这比使用多个-e参数要好得多......

You can also use a run handler or export:
您还可以使用运行处理程序或导出：
osascript -e 'on run argv
item 1 of argv
end run' aa
osascript -e 'on run argv
item 1 of argv
end run' -- -aa
osascript - -aa <<'END' 2> /dev/null
on run {a}
a
end run
END
export v=1
osascript -e 'system attribute "v"'
I don't know any way to get STDIN. on run {input, arguments}only works in Automator.
我不知道有什么办法可以得到 STDIN。on run {input, arguments}仅适用于 Automator。
