quickreplace - a CLI tool written in Rust

quickreplace allows you to replace every occurence of a string of your choosing within a file and write the changed text to an output file

This code originates from the example found in the book:

Programming Rust - Fast, Safe Systems Development

- by Jim Blandy, Jason Orendorff and Leonora F.S. Tindall.

This particular example can be found in Chapter 2: A tour of Rust - Filesystems and Command-Line Tools

Usage: quickreplace <target> <replacement> <INPUT> <OUTPUT>

quickreplace expects 4 Arguments:

1. target - the String to search for.

3. INPUT - the path to a file containing the contents to filter.
4. OUTPUT - the path to a file to write the filtered contents to.

Examples:

• Replace every occurence of "World" in Hello.txt with "Rust" and write the output to Hello_Copy.txt:

quickreplace "World" "Rust" ./Hello.txt ./Hello_Copy.txt

• Replace every occurence of "F" in Grades.csv with "A" and write the filtered contents back into Grades.csv:

quickreplace "F" "A" ./Grades.csv ./Grades.csv
