I have some long log files. I can view the last lines with tail -n 50 file.txt
, but sometimes I need to edit those last lines.
How do I jump straight to the end of a file when viewing it with nano
?

Open the file with nano file.txt
.
Now type Ctrl + _ and then Ctrl + V
Many editors support the +NNN
option on the command line to jump directly to line NNN. Luckily for you, nano
appears to jump to the end if the line number given is past the end of file, so you could use something like:
nano +999999 file
That also works in joe
, but not in, e.g. less
or VIM, they complain about going past EOF. (at least the ones on my system. less +G file
and vi +$ file
work in those.)
Of course something like $EDITOR +$(wc -l file) file
would probably work in most editors, but that's a bit silly and involves reading the file twice.
nano
could change their positioning argument behavior in the future. That's why I like ghaberek
's answer more.

From the built-in Nano help (^G
):
M-\ (^Home) Go to the first line of the file
M-/ (^End) Go to the last line of the file
So, press Alt+\ to go to the first line or press Alt+/ to go to the last line.
/
is near the bottom of the keyboard and \
is near the top.If you want a command, you could write a function in your .bashrc
or .bash_aliases
to use the line count from wc
:
function nano-end {
# if the file exists, jump to the end
# otherwise, just open an empty nano
[ -f "$1" ] && nano +$(wc -l "$1") || nano
}
Now just type nano-end filename
to open the file to its last line!
[[ .. ]]
where unnecessary, in this instance an ordinary test command [ .. ]
is appropriate. Further, don't use ` .. `
when the $( .. )
can be used. And don't forget to double quote the argument.

OP wants me to add an answer for jumping to the last line in vim
.
ESC + ShiftG will get you to the beginning of the last line.
ESC + ShiftGA will get you to the end of last line and insert mode will be activated.
C-o G
. Not that you would want to do that if you were using vim right...

Ctrl+End is working, if you have a recent compiled version of nano
editor
If you don't know, how to do it, you may read Compiling Nano editor with options
You can see the manual page of nano to find out the answer yourself. Just type
man nano
And hit Enter.
I hope you'll find another exciting things too.
Note: Just press ^V to reach the end ...
