-**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
