How do I 'cat' a text file but start from the bottom instead of top

  • 772

I have a very big text log file of about 37MB.
Using cat file | more I can view the file contents one page at a time.

The problem is that this always starts from the top - the old entries.
How can I make it start from the bottom where the newer entries are then move up page by page?

    Try the tac command, which reverses the input, line by line.

    Alternatively, less is more. Start at the end of the file using +G:

    less +G some-file

    You might have to get used to pressing b (which jumps back a screen) instead of Space.
