tac

Display and concatenate files with lines in reversed order. See also: cat. More information: https://www.gnu.org/software/coreutils/tac.

  • Concatenate specific files in reversed order:

tac {{path/to/file1 path/to/file2 ...}}

  • Display stdin in reversed order:

{{cat path/to/file}} | tac

  • Use a specific separator:

tac --separator {{,}} {{path/to/file1 path/to/file2 ...}}

  • Use a specific regex as a separator:

tac --regex --separator {{[,;]}} {{path/to/file1 path/to/file2 ...}}

  • Use a separator before each file:

tac --before {{path/to/file1 path/to/file2 ...}}
