vi - jumping to the end of text


hi everybody..

i am using VI editor to read(&edit) some huge log files. I need to scroll down to the end of the file, but it is like 100000 lines. Is there a short cut for this?

if the name of the file is mylog

then use this command at the command line

Code:
tail mylog
or if you want to view the last 15 lines,

then

Code:
tail -15 mylog
if you want to edit the file then for example last 30 lines

Code:
wc -l mylog
the above will give you the number of lines

then

let's say there are 10,000 lines

then do some simple math and you will only have to edit the last 30 lines.

and then,

Code:
head -9970 mylog  > upperfile;tail -30 mylog > lowerfile;pico lowerfile
will open the pico editor and let you edit the last 30 lines of the file

and then

when you are finished with editing the file with the pico editor(who uses vi editor nowadays?) save and exit by pressing ctrl x

then at the commandline

Code:
cat upperfile lowerfile > mylog
will give you a new mylog with the last 30 lines modified to your taste and needs.

I don't remember of any shortcut to jump to the end of file (this does not mean it does not exist, anyway). However you can do Ctrl-G to visualize the number of lines and then jump to the last line with :nnn, where nnn is the number of lines above. You can also consider Ctrl-F and Ctrl-B to jump forward and back by one page, respectively.

Just typing G (uppercase g) will take you to the last line in a file.

'G' is what I use too. ':$' also works, which is worth a mention because you can use it within a regex (or any other Vi operation). e.g. :5,$d to delete everything from line 5 to end-of-file.
