# minigrep

Classic command line search tool `grep` (`g`lobal search `r`egular `e`xpression and `p`rint).

In the simplest use case, `grep` searches a specified file for a specified string.

Reference: Chapter 12 of The Book: [chap12](https://doc.rust-lang.org/book/ch12-00-an-io-project.html)

### Build

```

$ git clone https://github.com/jiisanda/minigrep.git

$ cargo build

```

### Running Tests

```

$ cargo tests

```

### Searching

```

$ cargo run --  

```

This will get the output in the terminal. If the output is expected in output.txt file.

```

$ cargo run --   > ../output.txt

```

### For Case Sensitive Searching

For case sensitive searching, environment variables are used...

```

$ IGNORE_CASE=1 cargo run --  

```

In case of Powershell:

```

PS> $Env:IGNORE_CASE=1; cargo run --  

```

This will make `IGNORE_CASE` persist for the remainder of the shell session. It can be unset with `Remove-Item` cmdlet:

```

PS> Remove-Item Env:IGNORE_CASE

```
