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.

你可以简单地使用下面的简单方法:

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

其他回答

如果你不需要关心效率,就试试下面的方法。

zip -r foo.zip foo/*
unzip -LL foo.zip

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)

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bash,不重命名:

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