Rename files adding their parent folder name

In a small python script, renaming files recursively (folders as well as sub folders):

#!/usr/bin/env python3
import shutil
import os
import sys

dr = sys.argv[1]

for root, dirs, files in os.walk(dr):
    for f in files:
        shutil.move(root+"/"+f, root+"/"+root.split("/")[-1]+f)

How to use

• Copy the script into an empty file, save it as rename_files.py

• Run it with the directory as an argument:

  python3 /path/to/rename_files.py /directory/with/files
  

Note

As always, first try on a sample!

Explanation

The script:

• Walks through the directories, looking for files.

• If files are found, it splits the path to the file with the delimiter "/", keeping the last in the row (which is the parent's folder name) , to be pasted before the file's name:

  root.split("/")[-1]
  

• Subsequently, move the file to the renamed one:

  shutil.move(root+"/"+f, root+"/"+root.split("/")[-1]+f)
  

Using only shell (bash) with a little help from mv:

#!/bin/bash
shopt -s globstar  ##globstar will let us match files recursively
files=( /foo/bar/**/*.jpg )  ##Array containing matched files, mention where to search and what files here
for i in "${files[@]}"; do 
    d="${i%/*}"  ##Parameter expansion, gets the path upto the parent directory
    d_="${d##*/}"  ##gets the name of parent directory
    f="${i##*/}"  ##gets the file name
        echo mv "$i" "$d"/"${d_}""$f"  ##renaming, remove echo after confirming what will be changed and you are good
done

Example:

$ shopt -s globstar
$ files=( /foo/bar/**/*.jpg )
$ for i in "${files[@]}"; do d="${i%/*}"; d_="${d##*/}"; f="${i##*/}"; echo mv "$i" "$d"/"${d_}""$f"; done
mv /foo/bar/KT/633-ROYAL/4.jpg /foo/bar/KT/633-ROYAL/633-ROYAL4.jpg
mv /foo/bar/KT/633-ROYAL/5.jpg /foo/bar/KT/633-ROYAL/633-ROYAL5.jpg
mv /foo/bar/KT/633-ROYAL/6.jpg /foo/bar/KT/633-ROYAL/633-ROYAL6.jpg
