如何在Linux下将所有文件夹和文件重命名为小写?

我必须递归地重命名一个完整的文件夹树，这样就不会出现大写字母(这是c++源代码，但这无关紧要)。

忽略CVS和Subversion版本控制文件/文件夹的加分项。首选的方法是shell脚本，因为shell应该在任何Linux机器上可用。

关于文件重命名的细节有一些有效的争论。

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

使用排版:

typeset -l new        # Always lowercase
find $topPoint |      # Not using xargs to make this more readable
  while read old
  do new="$old"       # $new is a lowercase version of $old
     mv "$old" "$new" # Quotes for those annoying embedded spaces
  done

在Windows上，像Git Bash这样的模拟可能会失败，因为Windows在本质上不区分大小写。对于这些，添加一个步骤，mv的文件首先到另一个名称，如“$old.tmp”，然后到$new。

其他回答

这里的解决方案都不适合我，因为我所在的系统无法访问perl重命名脚本，而且有些文件包含空格。然而，我发现了一个有效的变体:

find . -depth -exec sh -c '
    t=${0%/*}/$(printf %s "${0##*/}" | tr "[:upper:]" "[:lower:]");
    [ "$t" = "$0" ] || mv -i "$0" "$t"
' {} \;

归功于“Gilles 'SO-停止作恶”，在Unix和Linux StackExchange上看到类似问题“将整个目录树更改为小写名称”的答案。

for f in `find`; do mv -v "$f" "`echo $f | tr '[A-Z]' '[a-z]'`"; done

这是一个小的shell脚本，做你所要求的:

root_directory="${1?-please specify parent directory}"
do_it () {
    awk '{ lc= tolower($0); if (lc != $0) print "mv \""  $0 "\" \"" lc "\"" }' | sh
}
# first the folders
find "$root_directory" -depth -type d | do_it
find "$root_directory" ! -type d | do_it

注意第一个find中的-depth动作。

for f in `find -depth`; do mv ${f} ${f,,} ; done

Find -depth打印每个文件和目录，目录的内容在目录本身之前打印。${f，，}将文件名小写。
