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

下面是我的次优解决方案，使用Bash shell脚本:

#!/bin/bash
# First, rename all folders
for f in `find . -depth ! -name CVS -type d`; do
   g=`dirname "$f"`/`basename "$f" | tr '[A-Z]' '[a-z]'`
   if [ "xxx$f" != "xxx$g" ]; then
      echo "Renaming folder $f"
      mv -f "$f" "$g"
   fi
done

# Now, rename all files
for f in `find . ! -type d`; do
   g=`dirname "$f"`/`basename "$f" | tr '[A-Z]' '[a-z]'`
   if [ "xxx$f" != "xxx$g" ]; then
      echo "Renaming file $f"
      mv -f "$f" "$g"
   fi
done

文件夹都正确地重命名，mv在权限不匹配时不会询问问题，CVS文件夹也不会重命名(不幸的是，该文件夹内的CVS控制文件仍然会重命名)。

由于“find -depth”和“find | sort -r”都以可用于重命名的顺序返回文件夹列表，我更喜欢使用“-depth”来搜索文件夹。

更小的，我很喜欢:

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

在不区分大小写的文件系统上，比如OS X的HFS+，你会想要添加-f标志:

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

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。

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?

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。
