grepru's Issues

Create a function that searches for a word in multiple files

-a, --all-file
Searching for the word in multiple files

Example:

grepru "hello" --all-file || grepru "hello" -a

output

words.txt
files.txt
exemple.txt

Functionality - Print count of selected lines per FILE

This feature should add the following optional argument to grepru cli.
-c, --count print only a count of selected lines per FILE

This allows grepru to effectively print a count of how many times that line appears in the text.

Example:
words.txt >

hello
hello
hi

command:

grepru "hello" -c words.text

should print:

2

command:

grepru "hi" -c words.text

should print:

1

implement `version` functionality

This functionality allows the user to print out the current version of grepru.

Example.

grepru --version or grepru -V
// Should print
v1.0.1

Implement unit test for fn find_matches

Implement a unit test for function fn find_matches(args: &Cli, reader: &mut BufReader<File>) that belongs to the matcher module.

Prefix each line of output with the 1-based line number within its input file

-n, --line-number
Prefix each line of output with the 1-based line number within its input file.

Example:

words.text>

hi // Line number 1
mike // Line number 2
hello  // Line number 3

grep "hello" -n words.txt

output

3:hello
