重命名(正则)

这并不是OP所要求的，但我希望在这一页上找到:

一个“slugify”版本用于重命名文件，使它们类似于url(即只包括字母数字，点和破折号):

rename "s/[^a-zA-Z0-9\.]+/-/g" filename

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。

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/*

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。

使用bash，不重命名:

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

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 {} +
