shell - 使用 awk 执行 shell 脚本在 AppleScript 中失败，但相同的 awk 命令在终端中有效

问题描述

使 shell 脚本在 AppleScript 中工作。

终端中的以下工作：

awk -F\" '/kMDItemTextContent/{print $2}' /Users/john/Desktop/PDFTags/mdimport.txt

但是同一行， with do shell script，在脚本编辑器中引发错误。

do shell script "awk -F\" '/kMDItemTextContent/{print $2}' /Users/john/Desktop/PDFTags/mdimport.txt"

这是来自脚本编辑器中的回复：

tell current application do shell script "awk -F\" '/kMDItemTextContent/{print $2}' /Users/john/Desktop/PDFTags/mdimport.txt"
--> error "sh: -c: line 0: unexpected EOF while looking for matching `\"' sh: -c: line 1: syntax error: unexpected end of file" number 2

作为参考，这里是 mdimport.txt 的上下文

解决方案

查看错误消息的一部分：

寻找匹配的 `\"' 时出现意外的 EOF

它指的是由以下分配的字段分隔符：-F

在这种情况下，您需要单引号和转义单个双引号。

do shell script "awk -F'\"' '/kMDItemTextContent/{print $2}' /Users/john/Desktop/PDFTags/mdimport.txt"

结果：

"这里是用于测试例程的文本文件内容。\n\n哈希标记测试文档\n\n#HashTag1 这是第一个哈希标记。\n#HashTag2 这是第二个哈希标记。\n\nThe以下井号标签在段落的内部和结尾："
