如何在Linux上将所有文件夹和文件重命名为小写? [英] How do I rename all folders and files to lowercase on Linux?

问题描述

我必须递归地重命名完整的文件夹树，以使任何地方都没有大写字母(这是C ++源代码，但这没关系).

I have to rename a complete folder tree recursively so that no uppercase letter appears anywhere (it's C++ source code, but that shouldn't matter).

忽略CVS和Subversion版本控制文件/文件夹的奖励点.首选方法是shell脚本，因为shell应该在任何Linux机器上都可用.

Bonus points for ignoring CVS and Subversion version control files/folders. The preferred way would be a shell script, since a shell should be available on any Linux box.

关于文件重命名的细节，有一些有效的论据.

There were some valid arguments about details of the file renaming.

1. 我认为具有相同小写字母名称的文件应被覆盖；这是用户的问题.在忽略大小写的文件系统上签出时，它也会用后者覆盖第一个文件.

1. I think files with the same lowercase names should be overwritten; it's the user's problem. When checked out on a case-ignoring file system, it would overwrite the first one with the latter, too.

我会考虑使用A-Z字符并将其转换为a-z，其他所有内容都只是在引发问题(至少在源代码中如此).

I would consider A-Z characters and transform them to a-z, everything else is just calling for problems (at least with source code).

在Linux系统上运行构建将需要该脚本，因此我认为应省略对CVS或Subversion版本控制文件的更改.毕竟，这只是从头开始.也许出口"更合适.

The script would be needed to run a build on a Linux system, so I think changes to CVS or Subversion version control files should be omitted. After all, it's just a scratch checkout. Maybe an "export" is more appropriate.

推荐答案

使用"rename"命令的简洁版本:

find my_root_dir -depth -exec rename 's/(.*)\/([^\/]*)/$1\/\L$2/' {} \;

这避免了在文件之前重命名目录并尝试将文件移至不存在的目录(例如，将"A/A"移至"a/a")的问题.

This avoids problems with directories being renamed before files and trying to move files into non-existing directories (e.g. "A/A" into "a/a").

或者，更详细的版本，而不使用"rename".

Or, a more verbose version without using "rename".

for SRC in `find my_root_dir -depth`
do
    DST=`dirname "${SRC}"`/`basename "${SRC}" | tr '[A-Z]' '[a-z]'`
    if [ "${SRC}" != "${DST}" ]
    then
        [ ! -e "${DST}" ] && mv -T "${SRC}" "${DST}" || echo "${SRC} was not renamed"
    fi
done

P.S.

后者使move命令(例如"svn mv")具有更大的灵活性.

P.S.

The latter allows more flexibility with the move command (for example, "svn mv").
