headtailx

Mitchell P. Krawiec-Thayer

This library provides headx and tailx commands which behave similarly to the head and tail commands, extended with support for binary data formats.

Supported file types include:

• Feather files
• Pickle files
• Parquet files
• HDF5 files
• XLSX

Example

Let's compare head and headx for a Feather file. Here's the standard head command:

$ head test.feather -n 4

ARROW1����H

The above output is binary data, which is not very useful. Now let's try headx:

$ headx -n 4 data.feather

 timestamp  flavor color  foobar
    10 strange   red       9
    20      up  blue       8
    30   charm  None       7

Installation

To install headtailx, simply run:

pip install headtailx

Use

Simply replace head with headx (and likewise tail -> tailx) when previewing binary data formats. For example headx <filename> -n 3 would show the first 3 lines.
