vi copy from line number to line number

You can use split, or sed

Lets use command sed for example

in below given example we have start line number: 143 end line number 201 and file name: filter.log
output to file called outfile.log

# sed -n '143,201p' filter.log > outfile.log

other way to achieve copy:
Block selection VI

Using marker we can achieve that too.

Type 

mk

to mark this spot as 

k

.
Go to the end of the section you want.

Type: y’k (y= Yank, , k) To yank from the mark to the current location.

Now p will do your job

Also you could use d’k to cut/delete.

type
3) :’a,’e s/^/# /

You can also use line numbers,
1 to $ ($ is the last line)
solitary % for everyline
. or blank for the current line.
