limiting characters upto <xyz> columns
Hi,
Recently i did some code changes in one of the text file.
During the code review,i've been asked to allign the comments
in this file to XYZ columns(say XYZ=40).
Now the problem is that this file is a huge one and
it would be really pathetic if i go ahead and do it manually.
I think there must be a better way of doing it,Can it be done
through a shell script ?
Can this variable(COLUMNS) is used for doing the same?
[amit@localhost ~]$ set|grep -i columns
COLUMNS=155 <===

Ommit the numbers or any characters only at 7th or 8th columns after the dot (.) . Since the group column has 1 and 2 spaces.

dadadodo
dadadodo(1) General Commands Manual dadadodo(1)
NAME
dadadodo - exterminate all rational thought
SYNOPSIS
dadadodo [ options ] [ input-files ]
DESCRIPTION
dadadodo is a program that analyses texts for Markov chains of word probabilities and then generates random sentences based on those proba-
bilities. Sometimes these sentences are nonsense, but sometimes they cut right through to the heart of the matter and reveal hidden mean-
ings.
OPTIONS
dadadodo accepts the following options:
-c, -count n
Generate n sentences.
-h, -help
Show summary of options and exit.
-html Output HTML instead of plain text.
-l, -load file
Load compiled data from file ('-' for standard input).
-o, -output file
Save compiled data in file ('-' for standard output).
-p, -pause s
Delay s seconds between paragraphs.
-w, -columns columns
Format output for a device columns character cells in width. If not specified, the value of the environment variable COLUMNS is
used to determine the width. If that variable is not defined, a width of 72 is assumed.
NOTES
Non-option arguments are input files. These should be text files, but may be mail folders or HTML. MIME messages are handled sensibly.
When no output file is specified, sentences will be generated from the input data directly. However, loading a saved file is far faster
than re-parsing the text files each time.
ENVIRONMENT
COLUMNS
Determines the width (in character cells) of the output if the -w, -columns option is not used. If not set, a width of 72 is
assumed.
