How to get particular Line:
source: https://kb.iu.edu/d/adxw
To make vi start at a particular line in a file, add +line_num to the command you use to start vi. Replaceline_num with the line number, for example:
vi +36 foo.c
If you're already in vi, you can use the goto command. To do this, press Esc, type the line number, and then press Shift-g. If you press Esc and then Shift-g without specifying a line number, it will take you to the last line in the file.
You can also use the ex command line to go to a line. (For information about the ex mode, see How do I use the vi text editor?) For instance, if you wanted to go to line 14, you could press Esc and then enter:
:14
To search forward for some text, use the / (forward slash) command. Press Esc and then enter /pattern, replacing pattern with the text for which you want to search forward. For example, to find every instance of the word "blimp", enter:
/blimp
To look for the next occurrence after the first, either press n or press / again and then press Enter. To go back to a previous occurrence, press Shift-n. To search backwards in a file, use the ? command.
To see what line you're on at any time, press Ctrl-Shift-g. To number all lines, press Esc and enter:
:set number
