A command line application in Rust

• This is a tool where we can give a string and a path, and it will print only the lines containing the given string.
• I distributed it with cargo in this link.
• We are able to run the tool like this:

$ cat test.txt
apple 1
bee 2
cat 3
dog 4
apple 5
$ grrs_hj apple test.txt
apple 1
apple 5

project setup

1. Clone the repo:

git clone https://github.com/JuliaJHL/week2-rust-mini-proj.git

2. cd into the repo:

cd week2-rust-mini-proj

3. compile the project:

cargo build --release

4. run the project:

cargo run -- xxx(pattern) xxx(path)

examples:

I created a test.txt with the following contents:

apple 1
bee 2
cat 3
dog 4
apple 5

When we apply cargo run -- apple test.txt, it would only return:

apple 1
apple 5

Distributing with cargo

I made package info updates in Cargo.toml and pushlished it via:

cargo login
cargo publish

Therefore, you can install grrs_hj and run it without cloning the repo by implementing the following commands directly:

cargo install grrs_hj
grrs_hj xxx(pattern) xxx(path)

Here is an example:
