在 Mac OS X 中从命令行对文件执行“获取信息”

Question

如果您在 Finder 中点击Command- ，您将如何从命令行显示“获取信息”窗口I？我可以用applescript写出来……但如果可以的话，我会远离。

Answer 1

这还支持多个文件并使 Finder 处于活动状态。仅在 10.4 及更早版本中才需要 utxt 方法。

si() {
    osascript - "$@" <<-END > /dev/null 2>&1
    on run args
    tell app "Finder"
    activate
    repeat with f in args
    open information window of (posix file (contents of f) as alias)
    end
    end
    end
    END
}

STDOUT 被重定向，因为 osascript 打印最后一个表达式的结果，而 STDERR 则因为 10.8 显示类似 CFURLGetFSRef 的警告，当相对路径转换为别名时，此 URL 没有方案。

Answer 2

这是我的脚本的更新版本（包括原始来源的归属，正如我几年前发现的那样）。功能上的主要变化是，它将处理包含 MacRoman 和 UTF-8（ASCII 之外的任何内容）之间编码不相同的字符的路径名。

#!/bin/sh
# Requires a POSIX-ish shell.

    #      include a BOM
    #   or produce native byte ordering

}

    exit 2

set -- "$(printf %s "$1" | utf8_to_AppleScript_utxt)"

# 10.4 requires script text to be in the primary encoding (usually MacRoman)
