命令以255个字符截断所有文件名 [英] Command to truncate all filenames at 255 characters

问题描述

在bash shell中打开了一个NTFS目录.什么命令将递归地将目录中的所有文件名截断为ext3所需的255个字符的限制?

An NTFS directory is open in a bash shell. what command will recursively truncate all filenames in a directory to the 255 character limit required for ext3?

推荐答案

如果可以访问Windows shell，则可以使用:

If you have access to a Windows shell, you can use:

@echo off
setlocal EnableDelayedExpansion

REM  loop over all files in the cwd
for /f %%a in ('dir /a-d /b') do (
   REM  store this filename in a variable so we can do substringing
   set ThisFileName=%%a
   REM  now take a substring
   set ThisShortFileName=!ThisFileName:~0,255!
   REM  finally, the rename:
   echo ren %%a !ThisShortFileName!
)


:EOF
endlocal

(注意:我在重命名命令之前添加了一个回显，因此您可以在实际运行它之前直观地验证它是否可以工作.在我的机器上可以工作.)

(Note: I have added an echo before the rename command just so you can visually verify that it works before actually running it. Works on my box.)

我确定现在在* nix框上的人可以为bash编写类似的脚本，但是我陷入了Windows世界:)

I'm sure somebody who's on a *nix box right now could make a similar script for bash, but I'm stuck in Windows world :)

祝你好运！
