**What it does**

tac is a Linux command that allows you to see a file line-by-line backwards. It is named by analogy with cat.

Mandatory arguments to long options are mandatory for short options too:

  -b, --before             attach the separator before instead of after
  -r, --regex              interpret the separator as a regular expression
  -s, --separator=STRING    use STRING as the separator instead of newline

-----

**Example**

Input file:

 0 1 2 3 4 5 # 6 7 8 9


default settings:

 9 8 7 6 # 5 4 3 2 1 0

with option -s 5:
 # 6 7 8 9 0 1 2 3 4 5

with option -b and -s 5:

 5 # 6 7 8 9 0 1 2 3 4
