51 **What it does**
|
|
|
52
|
|
|
53 tac is a Linux command that allows you to see a file line-by-line backwards. It is named by analogy with cat.
|
|
|
54
|
|
|
55 Mandatory arguments to long options are mandatory for short options too:
|
|
|
56
|
|
|
57 -b, --before attach the separator before instead of after
|
|
|
58 -r, --regex interpret the separator as a regular expression
|
|
|
59 -s, --separator=STRING use STRING as the separator instead of newline
