Batch rename file extensions, including subdirectories
提问by Glenn
I'm renaming empty file extensions with this command:
我正在使用以下命令重命名空文件扩展名：
rename *. *.bla
However, I have a folder with hundreds of such subfolders, and this command requires me to manually navigate to each subfolder and run it.
但是，我有一个包含数百个此类子文件夹的文件夹，此命令要求我手动导航到每个子文件夹并运行它。
Is there a command that I can run from just one upper level folder that will include all the files in the subfolders?
是否有一个命令可以只从一个上层文件夹运行，该文件夹将包含子文件夹中的所有文件？

@echo off
for /f "tokens=* delims= " %%i in ('dir /b/s/A-d') DO (
if "%%~xi" == "" rename "%%~fi" "%%~ni.bla"
)
Thanks @Wadih M. Find and rename files with no extension?
谢谢@Wadih M。查找和重命名没有扩展名的文件？

You can easily do this and many more things with the Perl module File::Find.
您可以使用 Perl 模块File::Find轻松完成此操作以及更多操作。
#!perl
use strict;
use warnings;
use File::Find;
my $extension = 'bla';
my $directory = '/tmp/test';
print "Files renamed:\n";
find( \&wanted, $directory );
sub wanted {
return if /\./;
return unless -f $File::Find::name;
if ( rename( $File::Find::name, "$File::Find::name.$extension" ) ) {
print " $File::Find::name -> $File::Find::name.$extension\n";
}
else {
print " Error: $! - $File::Find::name\n";
}
}

this will allow you to enter dirs with spaces in the names. (note the double % is for batch files, use a single % for command lines.)
这将允许您输入名称中带有空格的目录。（请注意，双 % 用于批处理文件，命令行使用单个 %。）
for /f "tokens=* delims= " %%a in ('dir /b /ad /s') do rename "%%a\*." "*.bla"

Try this
尝试这个
for /R c:\temp %I in (*. ) DO Echo rename %I "%~nI.bla"

You can use forto iterate over subdirectories:
您可以使用for迭代子目录：
for /d %x in (*) do pushd %x & ren *. *.bla & popd
When using it from a batch file you would need to double the %signs:
从批处理文件中使用它时，您需要将%符号加倍：
for /d %%x in (*) do pushd %%x & ren *. *.bla & popd

Using find and xargs and basename would make the expression easier to read
使用 find 和 xargs 和 basename 会使表达式更易于阅读
Prepare a rename shell script like this (corrected to handle multiple files)
准备一个像这样的重命名 shell 脚本（已更正以处理多个文件）
#!/bin/sh
if [ $# -lt 3 ]
then
echo "usage: rename.sh sufold sufnew file1 (file2 file3 ...) "
exit
fi
sufold=
sufnew=
shift
shift
for f in $*
do
echo "to mv " $f `dirname $f`"/"`basename $f $sufold`$sufnew
mv $f `dirname $f`"/"`basename $f $sufold`$sufnew
done
Then you could invoke that to each file matched your criteria, including recursive folder search by find command
然后你可以调用它来匹配你的条件的每个文件，包括通过 find 命令进行递归文件夹搜索
find . -name "*." | xargs rename.sh "." ".bla"
A more common sample
更常见的样本
find . -name "*.htm" | xargs rename.sh ".htm" ".html"
