更换/使用SED TAB [英] Replacing / with TAB using sed

问题描述

我需要一个标签来代替斜线字符我可以用awk提取目录名。

I need to replace a slash character with a tab to I can extract a directory name using awk.

/path/to/some/USEFUL_INFORMATION/in/some/path

我试图这样做，但它的作用是从我的输出把T的。

I tried doing this, but all it does is put a "t" at the from of my output.

sed -e 's/\//\t/g' filename

任何帮助将是AP preciated。

Any help would be appreciated.

推荐答案

首先，你可以使用其它字符作为取值/// 分隔符。命令

First, you can use another character as the s/// delimiter. The command

sed 's:ABC:DEF:g'

是相当于

sed 's/ABC/DEF/g'

它会使你的命令更具可读性，因为你没有逃跑的斜线。

It will make your command more readable because you'll not have to escape the slash.

说，有些SEDS不支持字符转义，如 \\ t 。它发生在我许多在Mac OS X，例如。我的解决办法是preSS控制+ V，然后标签字符：

Said that, some seds do not support character escaping such as \t. It happens to me a lot in Mac OS X, for example. My solution is to press Control+V and then the tab char:

sed 's:/:<Control+V><TAB character>:g'

在我的机器的结果是：

The result in my machine is:

$ pwd
/Users/brandizzi/sandbox/demo/mydemo
$ pwd | sed 's:/:        :g'
    Users   brandizzi   sandbox demo    mydemo

不过，如果你的目的是要放在awk中变量的所有路径的目录 $ 1 ， $ 2 等只是声明斜线是字段分隔符使用awk -F 标记：

However, if your intention is to put all path directories in awk variables $1, $2 etc. just declare the slash to be the field separator with awk -F flag:

$ pwd
/Users/brandizzi/sandbox/demo/mydemo
$ pwd | awk -F / '{print $3 " " $5}'
