Editing Files using Substrings

Your coworker Jane Doe currently has the username "jane" but she needs to it to "jdoe" to comply with your company's naming policy. This username change has already been done. However, some files that were named with Jane's previous username "jane" haven't been updated. For example, "jane_profile_07272018.doc" needs to be updated to "jdoe_profile_07272018.doc".

findJane.sh

#!/bin/bash

> oldFiles.txt

files=$(grep " jane " ../data/list.txt | cut -d' ' -f3)

for f in $files; do

   echo $f>>oldFiles.txt

done

changeJane.py

#!/usr/bin/env python3

import sys

import subprocess

f  = open(sys.argv[1], 'r')

path = '/home/<your-student-id-from-quicklab>'

for line in f.readlines():

  old = line.strip()

  new = old.replace('jane', 'jdoe')

  subprocess.run(["mv", path + str(old) ,path + str(new)])

f.close()
