Description

A CLI tool to convert numbers between bases, with as little typing as possible.

$ bs FFFE
[from hexadecimal]
  decimal     65534
  binary      1111111111111110
  octal       177776
$ bs -t d F
15

Installation

This is a Python 3 script, installed from PyPI using pip.

pip3 install base-convert-cli

Hasn't been tested on Windows.

Examples

If you don't specify a base, it does all common conversions.

$ bs 0
[from decimal]
  binary      0
  hexadecimal 0
  octal       0

[from binary]
<clipped output here>

Specify the base through the prefix 0b for binary, 0o for octal, 0d for decimal and 0x for hex.

$ bs 0xF
bs 0xF
[from hexadecimal]
  decimal     15
  binary      1111
  octal       17

Specifying base through a flag.

$ bs --from hex F
[from hexadecimal]
  decimal     15
  binary      1111
  octal       17

From base-36 (the maximum supported base, which uses the digits 0-9 and then a-z).

$ bs --from 36 zx1
[from base-36]
  decimal     46549
  binary      1011010111010101
  hexadecimal B5D5
  octal       132725

To base-7.

$ bs --to 7 54
[from decimal]
  base-7 105

[from hexadecimal]
  base-7 150

[from octal]
  base-7 62

Specifying both input and output bases.

$ bs --from hex --to dec F
15

Shorthand for lazy people.

$ bs -f h -t d F
15

Padding with zeroes.

$ bs --from decimal --to binary --pad 8 14
00001110

Setting precision for converting fractional numbers.

$ bs --prec 10 --from 3 --to decimal 0.1
0.3333333333

Aaaaand input through a pipe.

$ echo '5+10' | bc | bs -t h
[from decimal]
  hexadecimal F

[from octal]
  hexadecimal D
