# freq

Command-line utility application for displaying frequencies as histograms or bar charts, from the standard input.

For text input, `freq` returns a bar chart:

```shell

$ cat file.txt | freq

bar  ██████████▏ 1

foo  ████████████████████▏ 2

test ██████████████████████████████▏ 3

```

For numerical datasets, add the `--histogram` option to display a frequency distribution:

```shell

$ cat dataset.txt | freq --histogram --justify

  2-3 █████ 28

  3-4 █████████████████████████████▌ 167

  4-5 ██████████████████████████████▏ 170

  5-6 ████████████████████████████▌ 161

  6-7 █████████████ 73

  7-8 ██████████▌ 59

  8-9 █████████▎ 52

 9-10 ████▋ 26

10-11 ███▏ 17

11-12 ██▊ 15

```

## Installation

```bash

go get github.com/marcusolsson/freq

```

## Usage

Show top contributors to a Git repository:

```bash

git --no-pager log --format='%aN' | freq

```

Show most frequently used words in a document:

```bash

cat file.txt | tr -d '[:punct:]' | tr '[:upper:]' '[:lower:]' | tr '[:space:]' '\n' | freq

```

Show distribution of word lengths in a document:

```bash

cat file.txt | tr -d '[:punct:]' | tr '[:upper:]' '[:lower:]' | tr '[:space:]' '\n' | xargs -I'%' -n1 sh -c "echo % | wc -m" | freq --histogram

```

Show distribution of pull request age for a GitHub project, using [hub](https://hub.github.com/):

```

hub pr list -s opened -f '%ct%n' | xargs -n1 -I'{}' sh -c 'echo $(($(date +%s)-{}))' | freq --histogram --buckets=20

```
