シェルスクリプトで AppleScript 利用

Last updated at Posted at 2015-09-05

こんにちは。
シェルスクリプトで AppleScript(osascript コマンド)を使ってみました。Finder で選択されているファイルをリストする例です。(本稿末尾は Ruby での例)

ただし、第 2 例と第 3 例は変数(${delim})の展開を正しくできていません。

$ ./as_test.sh 
1:
Macintosh HD:Applications:
Macintosh HD:Users:
2:
Macintosh HD:Applications:${delim}Macintosh HD:Users:
3:
Macintosh HD:Applications:${delim}Macintosh HD:Users:
as_test.sh
#!/bin/sh
i=0
delim=\\n
# 1:
AS_RETURN=`
osascript << SCRIPT
  set text item delimiters of AppleScript to "${delim}"
  tell application "Finder" to get selection as text
SCRIPT`
i=`expr $i + 1`;echo "$i:\\n${AS_RETURN}"

# 2:
AS_RETURN=$(
osascript -e '
  set text item delimiters of AppleScript to "${delim}"
  tell application "Finder" to get selection as text
')
i=`expr $i + 1`;echo "$i:\\n${AS_RETURN}"

# 3:
AS_RETURN=$(
echo '
  set text item delimiters of AppleScript to "${delim}"
  tell application "Finder" to get selection as text
' | osascript - 
)
i=`expr $i + 1`;echo "$i:\\n${AS_RETURN}"

exit 0

また、第一例を Ruby で書いてみました。

as_test.rb
#!/usr/bin/ruby
delim="\n"
AS_RETURN=`osascript << SCRIPT
  set text item delimiters of AppleScript to "#{delim}"
  tell application "Finder" to get selection as text
SCRIPT`
puts "#{AS_RETURN}"
