HowTo view text file from the bottom on *nix?

Question

Hi.

I'm looking a simple command, like

$ less -{view_from_bottom_of_the_file_option} filename

or

$ vi -{start_viewer_from_the_bottom} filename

viewer, editor - what ever.

Thanks.

Answer 1

vi + filename (open the file filename at the last line)

or

vi +lineNumber filename (e.g. to open the file with filename at line 100, vi +100 filename)

Answer 2

tac $file | less

will reverse the order of the lines

Answer 3

You can use the +[num] command line option of vim.

+[num]  The cursor will be positioned on line "num" for the first
        file being edited.  If "num" is missing, the cursor will be
        positioned on the last line.

So to palce the cursor at the last line you can do:

vim + file_name

Answer 4

tail -n [lines] [file] will output the last [lines] of the [file]. When you add -f, the file will not be closed and you will see updates which are appended at the file.

Answer 5

less (on linux, FreeBSD, MacOSX) has the + option to send initial commands to less. An example in the man page uses it exactly to start viewing the file at last line. Like this:

less +G filename
