Is there an easy way to rename a group of files already contained in a directory, using Python?
Example: I have a directory full of *.doc files and I want to rename them in a consistent way.
X.doc -> "new(X).doc"
Y.doc -> "new(Y).doc"
This question is related to
python
file-io
rename
batch-rename
as to me in my directory I have multiple subdir, each subdir has lots of images I want to change all the subdir images to 1.jpg ~ n.jpg
def batch_rename():
base_dir = 'F:/ad_samples/test_samples/'
sub_dir_list = glob.glob(base_dir + '*')
# print sub_dir_list # like that ['F:/dir1', 'F:/dir2']
for dir_item in sub_dir_list:
files = glob.glob(dir_item + '/*.jpg')
i = 0
for f in files:
os.rename(f, os.path.join(dir_item, str(i) + '.jpg'))
i += 1

If you don't mind using regular expressions, then this function would give you much power in renaming files:
import re, glob, os
def renamer(files, pattern, replacement):
for pathname in glob.glob(files):
basename= os.path.basename(pathname)
new_filename= re.sub(pattern, replacement, basename)
if new_filename != basename:
os.rename(
pathname,
os.path.join(os.path.dirname(pathname), new_filename))
So in your example, you could do (assuming it's the current directory where the files are):
renamer("*.doc", r"^(.*)\.doc$", r"new(\1).doc")
but you could also roll back to the initial filenames:
renamer("*.doc", r"^new\((.*)\)\.doc", r"\1.doc")
and more.
import glob2
import os
def rename(f_path, new_name):
filelist = glob2.glob(f_path + "*.ma")
count = 0
for file in filelist:
print("File Count : ", count)
filename = os.path.split(file)
print(filename)
new_filename = f_path + new_name + str(count + 1) + ".ma"
os.rename(f_path+filename[1], new_filename)
print(new_filename)
count = count + 1

I like to have my music, movie, and picture files named a certain way. When I download files from the internet, they usually don’t follow my naming convention. I found myself manually renaming each file to fit my style. This got old realy fast, so I decided to write a program to do it for me.
This program can convert the filename to all lowercase, replace strings in the filename with whatever you want, and trim any number of characters from the front or back of the filename.
The program's source code is also available.
Be in the directory where you need to perform the renaming.
import os
# get the file name list to nameList
nameList = os.listdir()
#loop through the name and rename
for fileName in nameList:
rename=fileName[15:28]
os.rename(fileName,rename)
#example:
#input fileName bulk like :20180707131932_IMG_4304.JPG
#output renamed bulk like :IMG_4304.JPG

I've written a python script on my own. It takes as arguments the path of the directory in which the files are present and the naming pattern that you want to use. However, it renames by attaching an incremental number (1, 2, 3 and so on) to the naming pattern you give.
import os
import sys
# checking whether path and filename are given.
if len(sys.argv) != 3:
print "Usage : python rename.py <path> <new_name.extension>"
sys.exit()
# splitting name and extension.
name = sys.argv[2].split('.')
if len(name) < 2:
name.append('')
else:
name[1] = ".%s" %name[1]
# to name starting from 1 to number_of_files.
count = 1
# creating a new folder in which the renamed files will be stored.
s = "%s/pic_folder" % sys.argv[1]
try:
os.mkdir(s)
except OSError:
# if pic_folder is already present, use it.
pass
try:
for x in os.walk(sys.argv[1]):
for y in x[2]:
# creating the rename pattern.
s = "%spic_folder/%s%s%s" %(x[0], name[0], count, name[1])
# getting the original path of the file to be renamed.
z = os.path.join(x[0],y)
# renaming.
os.rename(z, s)
# incrementing the count.
count = count + 1
except OSError:
pass
Hope this works for you.

If you would like to modify file names in an editor (such as vim), the click library comes with the command click.edit(), which can be used to receive user input from an editor. Here is an example of how it can be used to refactor files in a directory.
import click
from pathlib import Path
# current directory
direc_to_refactor = Path(".")
# list of old file paths
old_paths = list(direc_to_refactor.iterdir())
# list of old file names
old_names = [str(p.name) for p in old_paths]
# modify old file names in an editor,
# and store them in a list of new file names
new_names = click.edit("\n".join(old_names)).split("\n")
# refactor the old file names
for i in range(len(old_paths)):
old_paths[i].replace(direc_to_refactor / new_names[i])
I wrote a command line application that uses the same technique, but that reduces the volatility of this script, and comes with more options, such as recursive refactoring. Here is the link to the github page. This is useful if you like command line applications, and are interested in making some quick edits to file names. (My application is similar to the "bulkrename" command found in ranger).
import glob2
import os
def rename(f_path, new_name):
filelist = glob2.glob(f_path + "*.ma")
count = 0
for file in filelist:
print("File Count : ", count)
filename = os.path.split(file)
print(filename)
new_filename = f_path + new_name + str(count + 1) + ".ma"
os.rename(f_path+filename[1], new_filename)
print(new_filename)
count = count + 1

nameList = os.listdir()
#loop through the name and rename

This replaces all underscores with hyphens in any non-hidden file in the current directory
