pyshuf2 2.0.0.post1

An attempt to bugfix an inexact python clone of GNU shuf and bring it into the modern Python 3 era.

pyshuf2

An inexact clone of GNU shuf. Free, implemented in Python.

Install

Usage

Same as shuf, but the script is invoked with pyshuf2. Read the GNU manual for shuf for more details. I created this fork because I needed it on an embedded system that ran an extremely limited copy of Linux, on 128 MB of RAM, and had only 16 GB of storage.

"Cookbook"

Generate a random number from 0 to 99

 $ pyshuf2 -i 0-99 -n 1
 73

Pick a random word from the dictionary (dictionary location may vary)

 $ pyshuf2 --input-file /usr/share/dict/words -n 1
 irreflectiveness

Shuffle the first 10 words from the dictionary

 $ head /usr/share/dict/words | pyshuf2
 aardvark
 aalii
 Aaron
 a
 aa
 Aani
 aam
 aardwolf
 A
 aal

Use input from the command line

 pyshuf2: error: argument -e/--echo: ignored explicit argument 'cho'
 $ pyshuf2 --echo one two three four five
 four
 two
 three
 one
 five

Features I implemented

--e, --echo
-i, --input-range
-n, --head-count

Features I have not implemented

-o, --output-file
--random-source
-r, --repeat
-z, --zero-terminated

Features I added that are not in GNU shuf

--input-file	specify an input file to read from

This is a Fork

Please note that this is a fork of jakekara/pyshuf.
