如何在Linux下将所有文件夹和文件重命名为小写?

我必须递归地重命名一个完整的文件夹树，这样就不会出现大写字母(这是c++源代码，但这无关紧要)。

忽略CVS和Subversion版本控制文件/文件夹的加分项。首选的方法是shell脚本，因为shell应该在任何Linux机器上可用。

关于文件重命名的细节有一些有效的争论。

I think files with the same lowercase names should be overwritten; it's the user's problem. When checked out on a case-ignoring file system, it would overwrite the first one with the latter, too. I would consider A-Z characters and transform them to a-z, everything else is just calling for problems (at least with source code). The script would be needed to run a build on a Linux system, so I think changes to CVS or Subversion version control files should be omitted. After all, it's just a scratch checkout. Maybe an "export" is more appropriate.

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

使用Larry Wall的文件名修复器:

$op = shift or die $help;
chomp(@ARGV = <STDIN>) unless @ARGV;
for (@ARGV) {
    $was = $_;
    eval $op;
    die $@ if $@;
    rename($was,$_) unless $was eq $_;
}

这很简单

find | fix 'tr/A-Z/a-z/'

(其中fix当然是上面的脚本)

使用"rename"命令的简明版本:

find my_root_dir -depth -exec rename 's/(.*)\/([^\/]*)/$1\/\L$2/' {} \;

这避免了在文件之前重命名目录以及试图将文件移动到不存在的目录(例如。"A/A"变成"A/A")。

或者，一个不使用“rename”的更详细的版本。

for SRC in `find my_root_dir -depth`
do
    DST=`dirname "${SRC}"`/`basename "${SRC}" | tr '[A-Z]' '[a-z]'`
    if [ "${SRC}" != "${DST}" ]
    then
        [ ! -e "${DST}" ] && mv -T "${SRC}" "${DST}" || echo "${SRC} was not renamed"
    fi
done

P.S.

后者允许更灵活地使用move命令(例如，“svn mv”)。

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 {} +

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):
