## Synopsis
``grepc PATTERN [FILE]``
``grepc -v PATTERN [FILE]``
``grepc -m= PATTERN [FILE]``
PATTERN = an extended regular expression (ERE).
FILE = a relative or absolute path to a file or directory.
## Description
**grepc** searches for PATTERN in each FILE. If no FILE is given, recursively
searches the working directory.
**grepc** prints all matches and their amount of occurrences.
Printed matches are sorted: 1. descending by amount of occurrences, 2. ascending
alphabetically by matching string.

## Options
### -m=, --min=
Minimum amount of occurrences. Matching string with less occurrences than the
given amount are not printed.
### -v, --verbose
Print a results summary additionally to the grep chart:
* amount of total matches
* amount of matching strings
* amount of files searched
### -V, --version
Print information about installed version of **grepc**, its license and
author(s).
## Usage examples
### Find strings wrapped in double quotes, sorted by popularity
Find strings that are enclosed in double quotes, with a minimum length of ten
characters:
``grepc '"[A-Za-z ]{10,}"' ./src``
**Output e.g.:**
```
156 "White Christmas"
155 "Candle in the Wind"
154 "In the Summertime"
153 "I will always love you"
152 "Rock around the Clock"
151 "Its now or never"
150 "We are the world"
```
**Note:** to find strings that are enclosed in single quotes, these must be
escaped as: ``'\''``.
E.g.: ``grepc "'\''[A-Za-z]{4,}'\''"``
### Find floating numbers sorted by popularity
Find floating numbers that have at least 14 decimal places.
``grepc -v '(\d\.\d+){16,}' ./src``
**Output e.g.:**
```
Found 177 matches in 83 out of 90 files.
There are 2 different matching strings:
91 3.14159265358979
86 2.71828182845904
```
