等效于Windows上的“剪切" [英] Equivalent to 'cut' on Windows

问题描述

我有一个文件，其条目如下.

I have a file which has entries as below.

/a/b/c/d/e/f
/a/b/c/g/k/l/f/j/h
/a/b/c/i/m/n/p

我需要Windows中的命令，该命令将从文件中删除'/a/b/c'部分.

I need a command in Windows which would remove the '/a/b/c' part from the file.

输出文件应该看起来像

d/e/f
g/k/l/f/j/h
i/m/n/p

我尝试将for命令与/用作分隔符，但无法获得预期的结果. 我该怎么办?

I tried using the for command with / as the delimiter, but I couldn't get the expected result. How can I do this?

推荐答案

@echo off

(for /f "tokens=3,* delims=/" %%a in (input.txt) do echo %%b) > output.txt

技巧"是要求第三个令牌和该行的其余部分.

And the "trick" is to ask for the third token and the rest of the line.

要直接从命令行使用它:

To use it directly from the command line:

(for /f "tokens=3,* delims=/" %a in (input.txt) do @echo %b) > output.txt

转义的百分号得到了简化，并且由于从命令行默认不启用echo off，因此需要在echo之前的@.

The escaped percent signs are simplified and, as from command line the echo off is not enabled by default, the @ before echo is needed.
