What type of problem you have encountered with 'vi' ?
The main problem i'm having with vi is, that i understand how to open a file on specific line, the thing I don't get is how to save the changes. For example, I've been trying to do something like this.
Code:
vi +5n myfile
:i
"Insert some text"
:w
:q
As I said, it only opened editor in Insert mode.
It's probably silly me
I've tried to use sed, and it helped, although that was the code I've found on Internet, but I don't understand completely the meaning of criterias yet.
p.s. I've managed to solve the given example using temp file, which is being an absolutely time and space consuming solution....

ppmquantall
ppmquantall(1) General Commands Manual ppmquantall(1)NAME
ppmquantall - run ppmquant on a bunch of files all at once, so they share a common colormap
SYNOPSIS
ppmquantall [-ext extension] ncolors ppmfile ...
DESCRIPTION
Takes a bunch of portable pixmap as input. Chooses ncolors colors to best represent all of the images, maps the existing colors to the new
ones, and overwrites the input files with the new quantized versions.
If you don't want to overwrite your input files, use the -ext option. The output files are then named the same as the input files, plus a
period and the extension text you specify.
Verbose explanation: Let's say you've got a dozen pixmaps that you want to display on the screen all at the same time. Your screen can
only display 256 different colors, but the pixmaps have a total of a thousand or so different colors. For a single pixmap you solve this
problem with ppmquant; this script solves it for multiple pixmaps. All it does is concatenate them together into one big pixmap, run
ppmquant on that, and then split it up into little pixmaps again.
(Note that another way to solve this problem is to pre-select a set of colors and then use ppmquant's -map option to separately quantize
each pixmap to that set.)
