NAME

tac - concatenate and print files in reverse


SYNOPSIS

tac [-br] [-s separator] [-B] [-S bytes] [file...]


DESCRIPTION

tac copies files or standard input to standard output with the order of records reversed.


OPTIONS

-b
Attach separator to the beginning of the record that it precedes in the file.

-B
Read files in binary mode.

-r
The separator is a regular expression.

-s STRING
Use STRING as record separator. Set to '' for paragraph mode. Defaults to newline.

size
-S BYTES
Number of bytes to read at a time. Defaults to 8192.


NOTES

  1. -B and -S are peculiar to this implementation of tac.

  2. Regular expressions reek of camel. Here are a few constructs to watch out for:

        \A, \Z, \z      anchors are not useful...
        ^ $             ...maybe with /m
        ()              capturing parenthesis are not useful
        |               alternation may match out of sequence
