### Command Line Interface
For finding lines in your text with certain words. Can be case sensitive or insensitive depending on the user. 

To run the program, 
## Upload the text file in the parent directory of the of the src folder, i.e., in the minigrep folder

To push the output to output.text -> cargo run <query> <filename> > output.txt
To change the case senstive -> export CASE_SENSITIVE=true and then unset CASE_SENSITIVE (this line only works for git bash)

# Like a personal mini-grep

## "lib.rs" contains:
# 1. run :
It first reads the file that is passed in the arguments, then calls search_case_senstive or search_case_insensitive based on the case preference and returns the lines if there are lines with the query in the text file.

# 2. search (both cases):
Searches for the lines that have contain the passed query and retirn it as a Vec<&str>
