Minigrep is a simplified version of the grep command line tool implemented in Rust.
It allows you to search for a specified term within a given file. The program supports both case-sensitive and case-insensitive search, depending on the value of the IGNORE_CASE environment variable.
To run the program, use the following command:
cargo run -- [term] [file]
Replace [term] with the term you want to search for, and [file] with the path to the file in which you want to search.
If you want the search to be case-insensitive, set the environment variable IGNORE_CASE to 1 before running the program.
$ IGNORE_CASE=1 cargo run -- [term] [file]
Or, if you are running on Windows:
PS> $Env:IGNORE_CASE=1; cargo run -- [term] [file]
Suppose you want to search for the term "hello" in a file named "example.txt" and perform a case-insensitive search. Here's how you would run the program:
IGNORE_CASE=1 cargo run -- hello example.txt
The program will display the lines in the file that contain the specified term.
