How do I rename files in sub directories?

Question
Is there any way of batch renaming files in sub directories?
For example:
Rename *.html
to *.htm
in a folder which has directories and sub directories.
Solution
Windows command prompt: (If inside a batch file, change %x to %%x)
for /r %x in (*.html) do ren "%x" *.htm
This also works for renaming the middle of the files
for /r %x in (website*.html) do ren "%x" site*.htm
OTHER TIPS
For windows, this is the best tool I've found:
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.
find . -regex ".*html$" | while read line;
do
A=`basename ${line} | sed 's/html$/htm/g'`;
B=`dirname ${line}`;
mv ${line} "${B}/${A}";
done
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)
In Bash, you could do the following:
for x in $(find . -name \*.html); do
mv $x $(echo "$x" | sed 's/\.html$/.htm/')
done
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$/htm/')
done
If you have forfiles (it comes with Windows XP and 2003 and newer stuff I think) you can run:
forfiles /S /M *.HTM /C "cmd /c ren @file *.HTML"
On Linux, you may use the 'rename' command to rename files in batch.
In bash use command rename :)
rename 's/\.htm$/.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!
Total Commander which is a file manager app, lets you list & select all files within its dir & sub-dirs, then you can run any of the total commander operations on them. one of them being: multi-rename the selected files.
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/"$1".new_extension"}' |csh
For Windows, I've made a convenient litte VBScript solution with regex-based renaming and Drag&Drop support. Give it a try if you like - put it in a vbs file and drop your folder on it in Explorer.
On Windows, The Rename does a pretty good job at that. Freeware, but not open source.
On Windows, you can find out opensource simple C# bulk file renamer application in https://filerenamer.codeplex.com works with a simple excel file. Give an excel file with two columns source and destination to this application and it's done.
On Unix, you can use rnm:
rnm -rs '/\.html$/.htm/' -fo -dp -1 *
Or
rnm -ns '/n/.htm' -ss '\.html$' -fo -dp -1 *
Explanation:
-ns
: name string (new name)./n/
is a name string rule that expands to the filename without the extension.-ss
: search string (regex). Searches for files with match.-rs
: replace string of the form/search_regex/replace_part/modifier
-fo
: file only mode-dp
: depth of directory (-1 means unlimited).
