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.

如果你使用Arch Linux,你可以从AUR安装rename)包,它提供了renamexm命令作为/usr/bin/renamexm可执行文件和一个手册页面。

它是一个非常强大的工具,可以快速重命名文件和目录。

转换为小写字母

rename -l Developers.mp3 # or --lowcase

转换为大写

rename -u developers.mp3 # or --upcase, long option

其他选项

-R --recursive # directory and its children

-t --test # Dry run, output but don't rename

-o --owner # Change file owner as well to user specified

-v --verbose # Output what file is renamed and its new name

-s/str/str2 # Substitute string on pattern

--yes # Confirm all actions

如果需要,您可以从这里获取示例Developers.mp3文件;)

在OS X中,mv -f显示“same file”错误,所以我重命名两次:

for i in `find . -name "*" -type f |grep -e "[A-Z]"`; do j=`echo $i | tr '[A-Z]' '[a-z]' | sed s/\-1$//`; mv $i $i-1; mv $i-1 $j; done

使用排版:

typeset -l new        # Always lowercase
find $topPoint |      # Not using xargs to make this more readable
  while read old
  do new="$old"       # $new is a lowercase version of $old
     mv "$old" "$new" # Quotes for those annoying embedded spaces
  done

在Windows上,像Git Bash这样的模拟可能会失败,因为Windows在本质上不区分大小写。对于这些,添加一个步骤,mv的文件首先到另一个名称,如“$old.tmp”,然后到$new。

使用bash,不重命名:

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

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”)。

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。
