如何通过终端获取最新文件的名称？ [英] How do I get the name of the newest file via the Terminal?

问题描述

我尝试为OS X创建用于 Keyboard Maestro 的宏，执行以下操作：

I'm trying to create a macro for Keyboard Maestro for OS X doing the following:

1. 根据创建的日期获取磁盘目录中最新文件的名称;


2. 粘贴文本最新文件：加上最新文件的名称。

其中一个选项是执行shell脚本 ，所以我认为这将为1.在Googling一点后我想出了：

One of its options is to "Execute a shell script", so I thought that would do it for 1. After Googling around a bit I came up with this:

cd /path/to/directory/
ls -t | head -n1

这会将其排序，并返回第一个文件名。然而，它似乎也包括一个换行，我不想要。至于2：我可以输出文本最新文件：与应用程序中的不同的操作，并粘贴文件名后面。但我想知道你是否不能返回随机文本+ ls 命令的结果。

This sorts it right, and returns the first filename. However, it also seems to includes a line break, which I do not want. As for 2: I can output the text "newest file: " with a different action in the app, and paste the filename behind that. But I'm wondering if you can't return "random text" + the outcome of the ls command.

所以我的问题是：我可以只使用 ls 命令吗？

So my question is: can I do this only using the ls command? And how do I get just the name of the latest file without any linebreaks or returns?

推荐答案

如何获得最新文件的名称，因为你已经在使用管道，只是抛出另一个：

Since you're already using pipes, just throw another one in there:

ls -t | head -n1 |awk '{printf("newest file: %s",$0)}'

（请注意，printf在结尾处不包含\\\
;这样可以避免换行）

(Note that the "printf" does not include a '\n' at the end; that gets rid of the linebreak)

编辑：

由于Arkku的建议，在第一行后退出awk，它看起来像：

With Arkku's suggestion to exit awk after the first line, it looks like:

ls -t | awk '{printf("newest file: %s",$0);exit}'
