如何使用批处理删除多个文件中某些字符后的字符串? [英] How to delete strings after certain character in multiple files using batch?

问题描述

我一直在尝试删除_1之后的一些字符并重命名该文件，但是卡住了.让我输入示例文件名以使其清楚.

I have been trying to delete some characters after _1 and rename the file but got stuck. let me put in sample file names to make it clear.

aero_name_1_3_7.png
glik_trol_1_5_2_9_5.png
this_that_1_3_1_9.png
....... and so on. 

因此，我的文件名包含完全相同的格式，但名称不同，因此我认为应使用标记和delims.重命名我的文件后，外观应为aero_name_1.png，glik_trol_1.png，this_that_1.png 这是我写的蝙蝠，但这是行不通的.如果有人可以建议，那就太好了.

So my filenames contain exact format but different names and hence I thought to use tokens and delims. After renaming my files should look aero_name_1.png, glik_trol_1.png, this_that_1.png Here is the piece of bat that I wrote but this does not work. If someone could suggest, that would be great.

for /F "tokens=1-4,* delims=_" %%a in ('dir /A-D /B "*.png"') do (
  move "%%a_%%b" "%%a%%~xb"
)

谢谢

推荐答案

查看您的第二个文件名，这是FOR/F循环的内容:

Looking at your 2nd file name, this is what the FOR /F loop has:

%%a=glik
%%b=trol
%%c=1
%%d=5
%%e=2_9_5.png

因此，您的MOVE命令变为:

So your MOVE command becomes:

move "glik_trol" "glik"

请注意，%%b没有扩展名

您可以使用

for /f "tokens=1-3* delims=_" %%a in ('dir /a-d /b *.png') do (
  move "%%a_%%b_%%c_%%d" "%%a_%%b_%%c%%~xd"
)

如果您对正则表达式感到满意，则可以使用我方便的 JREN.BAT 是可在任何本地运行的纯脚本从XP开始的Windows机器.这是执行非常精确的重命名操作的一种非常方便的方法.

If you are comfortable with regular expressions, then you could use my handy JREN.BAT utility - a hybrid JScript/batch script that renames files by performing a regular expression find and replace on the name. JREN.BAT is pure script that runs natively on any Windows machine from XP onward. It is a very convenient method to perform very precise rename operations.

假设您的 JREN.BAT 当前目录，或者更好的是，位于您PATH中的某个位置:

Assuming you have JREN.BAT in your current directory, or better yet, somewhere within your PATH:

jren "^([^_]+_[^_]+_[^_]+)_.*(\.png)$" "$1$2" /i

不需要批次.如果确实在批处理脚本中使用该命令，则应在命令前加上CALL前缀，因为JREN也是批处理脚本.

No batch is needed. If you do use the command in a batch script, then you should prefix the command with CALL because JREN is also a batch script.
