Remove first 2 characters and last two characters of each line
here's what im trying to do.
i have a file containing lines similar to this:
data.txt:
I need to remove the first two characters and the last two characters of each line. but i also need to be able to put those removed characters back to where they were before they were removed.
so, here's what i'm doing so far:
This only removes the first two characters of each line and the last two.
where im getting stuck is, how do i get back the removed characters?
a thought that crossed my mind is to first get the first two characters of each line line. save it to a file and do the same for the last two characters.
then find a way to merge firstwo.characters and lastwo.characters with data.txt.pruned so they look like the original text in data.txt?
i suppose the commands join may be used here. but im looking for something that can work on all Unix systems (portable), especially those systems that are considered "embedded". if awk can be used here, that'll be great.
I am using awk and it stops when it encounter line greater then 3000 character. Is there any command which will help me remove line greater then 3000 characters. (10 Replies)

Hello,
Is there a simpler way to remove special characters (color codes) from each lines in a log file?
I use sed like in the example below but I think there should be a more simple way to achieve the same result:
$ cat -vet file1
^, , , ,
Maybe to convert the file somehow?

fmt
fmt(1) User Commands fmt(1)NAME
fmt - simple text formatters
SYNOPSIS
fmt [-cs] [-w width | -width] [inputfile...]
DESCRIPTION
fmt is a simple text formatter that fills and joins lines to produce output lines of (up to) the number of characters specified in the -w
width option. The default width is 72. fmt concatenates the inputfiles listed as arguments. If none are given, fmt formats text from the
standard input.
Blank lines are preserved in the output, as is the spacing between words. fmt does not fill nor split lines beginning with a `.' (dot), for
compatibility with
nroff(1). Nor does it fill or split a set of contiguous non-blank lines which is determined to be a mail header, the first line of which
must begin with "From".
Indentation is preserved in the output, and input lines with differing indentation are not joined (unless -c is used).
fmt can also be used as an in-line text filter for vi(1). The vi command:
!}fmt
reformats the text between the cursor location and the end of the paragraph.
OPTIONS -c Crown margin mode. Preserve the indentation of the first two lines within a paragraph, and align the left margin of
each subsequent line with that of the second line. This is useful for tagged paragraphs.
-s Split lines only. Do not join short lines to form longer ones. This prevents sample lines of code, and other such
formatted text, from being unduly combined.
-w width | -width Fill output lines to up to width columns.
OPERANDS
inputfile Input file.
ENVIRONMENT VARIABLES
See environ(5) for a description of the LC_CTYPE environment variable that affects the execution of fmt.
