NAME
tac - concatenate and print files in reverse
SYNOPSIS
tac
[-br] [-s separator] [--before] [--regex] [--separator=separator]
[file...]
DESCRIPTION
This manual page
documents the GNU version of
tac.
tac
copies each given file, or the standard input if none are given or
when a file name of `-' is encountered, to the standard output with
the order of the records reversed. The records are separated by
instances of a string, or a newline if none is given. By default, the
separator string is attached to the end of the record that it follows
in the file.
OPTIONS
- -b, --before
-
The separator is attached to the beginning of the record that it
precedes in the file.
- -r, --regex
-
The separator is a regular expression.
- -s, --separator separator
-
Use
separator
as the record separator.
The long-named options can be introduced with `+' as well as `--',
for compatibility with previous releases. Eventually support for `+'
will be removed, because it is incompatible with the POSIX.2 standard.
