Rename files in sub directories

Question

Is there any way of batch renaming files in sub directories?

Example:

Rename *.html to *.htm in a folder which has directories and sub directories.

Answer 1

In Bash, you could do the following:

for x in $(find . -name \*.html); do
  mv $x $(echo "$x" | sed 's/\.html$/.htm/')
done

Answer 2

I'm sure there's a more elegant way, but here's the first thing that popped in my head:

for f in $(find . -type f -name '*.html'); do 
    mv $f $(echo "$f" | sed 's/html$/htm/')
done

Answer 3

For windows, this is the best tool I've found:

http://www.1-4a.com/rename/

It can do anything AND has the kitchen sink with it.

For Linux, you have a plethora of scripting languages and shells to help you, like the previous answers.

Answer 4

Windows command prompt: (If inside a batch file, change %x to %%x)

for /r %x in (*.html) do ren %x *.htm

Answer 5

find . -regex ".*html$" | while read line;
 do 
    A=`basename ${line} | sed 's/html$/htm/g'`;
    B=`dirname ${line}`;
    mv ${line} "${B}/${A}";
 done

Answer 6

In python

import os

target_dir = "."

for path, dirs, files in os.walk(target_dir):
    for file in files:
        filename, ext = os.path.splitext(file)
        new_file = filename + ".htm"

        if ext == '.html':
            old_filepath = os.path.join(path, file)
            new_filepath = os.path.join(path, new_file)
            os.rename(old_filepath, new_filepath)

Answer 7

On Linux, you may use the 'rename' command to rename files in batch.

Answer 8

AWK on Linux. For the first directory this is your answer... Extrapolate by recursively calling awk on dir_path perhaps by writing another awk which writes this exact awk below... and so on.

ls dir_path/. | awk -F"." '{print "mv file_name/"$0" dir_path/"$1".new_extension"}' |csh

Answer 9

For Windows, I've made a convenient litte VBScript solution with regex-based renaming and Drag&Drop support. Give it a try if you like - put it in a vbs file and drop your folder on it in Explorer.

Answer 10

In bash use command rename :)

 rename 's/\.htm$/.html/' *.htm

 # or

 find . -name '*.txt' -print0 | xargs -0 rename 's/.txt$/.xml/'

 #Obs1: Above I use regex \. --> literal '.'  and  $ --> end of line
 #Obs2: Use find -maxdepht 'value' for determine how recursive is
 #Obs3: Use -print0 to avoid 'names spaces asdfa' crash!

Answer 11

On Windows, The Rename does a pretty good job at that. Freeware, but not open source.

Answer 12

If you have forfiles (it comes with Windows XP and 2003 and newer stuff I think) you can run:

forfiles /S /M *.HTM /C "cmd /c ren @file *.HTML"
