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。

使用bash，不重命名:

find . -exec bash -c 'mv $0 ${0,,}' {} \;

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。

如果你不需要关心效率，就试试下面的方法。

zip -r foo.zip foo/*
unzip -LL foo.zip

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?

我在Mac OS X上发现的最简单的方法是使用http://plasmasturm.org/code/rename/:上的重命名包

brew install rename
rename --force --lower-case --nows *

——force即使目标文件名已经存在，也要重命名。 ——lower-case将文件名全部转换为小写。 替换文件名中所有空格序列为单个下划线字符。
