不能移植，只能使用Zsh，但是非常简洁。

首先，确保加载zmv。

autoload -U zmv

同时，确保extendedglob是打开的:

setopt extendedglob

然后使用:

zmv '(**/)(*)~CVS~**/CVS' '${1}${(L)2}'

递归到名称不是CVS的小写文件和目录。

冗长但“没有惊喜和装置的作品”

This script handles filenames with spaces, quotes, other unusual characters and Unicode, works on case insensitive filesystems and most Unix-y environments that have bash and awk installed (i.e. almost all). It also reports collisions if any (leaving the filename in uppercase) and of course renames both files & directories and works recursively. Finally it's highly adaptable: you can tweak the find command to target the files/dirs you wish and you can tweak awk to do other name manipulations. Note that by "handles Unicode" I mean that it will indeed convert their case (not ignore them like answers that use tr).

# adapt the following command _IF_ you want to deal with specific files/dirs
find . -depth -mindepth 1 -exec bash -c '
  for file do
    # adapt the awk command if you wish to rename to something other than lowercase
    newname=$(dirname "$file")/$(basename "$file" | awk "{print tolower(\$0)}")
    if [ "$file" != "$newname" ] ; then
        # the extra step with the temp filename is for case-insensitive filesystems
        if [ ! -e "$newname" ] && [ ! -e "$newname.lcrnm.tmp" ] ; then
           mv -T "$file" "$newname.lcrnm.tmp" && mv -T "$newname.lcrnm.tmp" "$newname" 
        else
           echo "ERROR: Name already exists: $newname"
        fi
    fi    
  done
' sh {} +

如何在Bash中转换字符串为小写?

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。

我需要在Windows 7上的Cygwin设置上这样做，并发现我在上面尝试的建议中出现了语法错误(尽管我可能错过了一个工作选项)。然而，这个解决方案直接来自Ubuntu论坛:-)

ls | while read upName; do loName=`echo "${upName}" | tr '[:upper:]' '[:lower:]'`; mv "$upName" "$loName"; done

(注意:我之前用下划线替换了空格:

for f in *\ *; do mv "$f" "${f// /_}"; done

)

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

如果你使用Arch Linux，你可以从AUR安装rename)包，它提供了renamexm命令作为/usr/bin/renamexm可执行文件和一个手册页面。

它是一个非常强大的工具，可以快速重命名文件和目录。

转换为小写字母

rename -l Developers.mp3 # or --lowcase

转换为大写

rename -u developers.mp3 # or --upcase, long option

其他选项

-R --recursive # directory and its children

-t --test # Dry run, output but don't rename

-o --owner # Change file owner as well to user specified

-v --verbose # Output what file is renamed and its new name

-s/str/str2 # Substitute string on pattern

--yes # Confirm all actions

如果需要，您可以从这里获取示例Developers.mp3文件;)
