Replace the Content in Files
Your task is to develop a script that can replace a specific string in all
.txt files in a given directory.Imagine that you are working as a data analyst for a large company and your team has just asked you to modify a key term that appears in many different report files. The files are all stored in one directory, and all have a
.txt extension. The task would be cumbersome to do manually, but thankfully, you know how to automate the process with a script.The first line of the input contains the string
s that you need to find in the files. The second line of the input contains the string r that you will replace s with. The third line of the input contains the directory where the files are located.The program should go through all
.txt files in directory d, find all occurrences of string s and replace them with string r. The program doesn't need to output anything.Input | Output |
