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。

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

)

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 {} +

我的剧本是基于以下这些精彩的回答:

如何在Bash中转换字符串为小写?

一行程序:

for F in K*; do NEWNAME=$(echo "$F" | tr '[:upper:]' '[:lower:]'); mv "$F" "$NEWNAME"; done

甚至:

for F in K*; do mv "$F" "${F,,}"; done

注意，这将只转换以字母K开头的文件/目录，因此要相应地进行调整。

如果你已经设置了重命名命令(例如，在Mac中通过brew install)，这是有效的:

rename --lower-case --force somedir/*

你可以简单地使用下面的简单方法:

rename 'y/A-Z/a-z/' *
