Project Objectives
This project aims to implement a grep-like CLI app in Rust, named lr_grustep
1.
It should be used like this:
grustep [-cinrv] [pattern] [file ...]
The following options should be available:
-c, --count
Only a count of selected lines is written to standard output.
-h Print a brief help message.
-i, --ignore-case
Perform case insensitive matching. By default, it is case sensitive.
-n, --line-number
Each output line is preceded by its relative line number in the file, starting at line 1.
The line number counter is reset for each file processed. This option is ignored if -c is specified.
-r, --recursive
Recursively search subdirectories listed.
-v, --invert-match
Selected lines are those not matching any of the specified patterns.
