Various tools for text extraction, representation, and analysis

Functions

---------

### `avg`

Calculate the average of input numbers

    $ cat data

    100

    100

    0

    $ avg < data

    66.666

### `commas`

Add commas to a given inputs numbers

    $ echo '100000 / 100000000' | commas

    100,000 / 100,000,000

### `field`

Grab a field from given input, Adapted from

http://www.brendangregg.com/Shell/field

    $ cat data.txt

    1 dave

    2 mike

    3 skye

    4 shaggy

    $ cat data.txt | field 2

    dave

    mike

    skye

    shaggy

or specify a field separator as the second argument

    $ cat /etc/passwd | field 7 :

    /usr/bin/false

    /bin/sh

    /usr/bin/false

    ...

- `$1` - The field number to extract, defaults to `1`

- `$2` - The field separator to be passed to awk, defaults to ` ` (whitespace)

### `freq`

Poor mans frequency count

    $ cat data

    a

    b

    c

    c

    c

    $ cat data | freq

       1 a

       1 b

       3 c

Using the data from above we can count the shells found in

`/etc/passwd`

    $ cat /etc/passwd | field 7 : | freq

          1 /bin/bash

          1 /bin/ksh

          1 /opt/local/bin/pdksh

          1 /usr/bin/pfksh
