Equivalent to 'cut' on Windows
提问by user3437212
I have a file which has entries as below.
我有一个文件，其中包含如下条目。
/a/b/c/d/e/f
/a/b/c/g/k/l/f/j/h
/a/b/c/i/m/n/p
I need a command in Windows which would remove the '/a/b/c'part from the file.
我需要在 Windows 中使用一个命令来'/a/b/c'从文件中删除该部分。
The output file should look like
输出文件应该看起来像
d/e/f
g/k/l/f/j/h
i/m/n/p
I tried using the forcommand with /as the delimiter, but I couldn't get the expected result.
How can I do this?
我尝试使用for命令 with/作为分隔符，但无法得到预期的结果。我怎样才能做到这一点？

@echo off
(for /f "tokens=3,* delims=/" %%a in (input.txt) do echo %%b) > output.txt
And the "trick" is to ask for the third token and the rest of the line.
而“技巧”是要求第三个标记和该行的其余部分。
To use it directly from the command line:
要直接从命令行使用它：
(for /f "tokens=3,* delims=/" %a in (input.txt) do @echo %b) > output.txt
The escaped percent signs are simplified and, as from command line the echo offis not enabled by default, the @before echois needed.
转义的百分号被简化，并且从命令行echo off默认情况下不启用，需要@before echo。
