Thanks Kato, that works just fine. Let me see if I can dissemble this.
NF checks to see that there are less then four fields(columns).
If so, save that line and go read the next line
Else print the previous line and the current line together. and go on to the next line
what does the '1' at the end do? if I leave it out, just the two line are printed. is it a flag that just has to be there and doesn't matter what its value is?
so to make it more robust as a script I can do something like:
cat clean.awk
running it:
I get the following mess. Changing it from a one-liner to a script somehow changed it.
Getting closer. The one-liner works, but I would like to document this as a script for a later programmer to maintain.
Hi,

how do I remove them?
Let me know.

I would like to remove carriage returns/line feeds in a text file, but in a specific cadence:

Read the next line, remove the cr/lf;

Text::Wrap(3pm) Perl Programmers Reference Guide Text::Wrap(3pm)NAME
Text::Wrap - line wrapping to form simple paragraphs
SYNOPSIS
Example 1
use Text::Wrap;
$initial_tab = " "; # Tab before first line
$subsequent_tab = ""; # All other lines flush left
print wrap($initial_tab, $subsequent_tab, @text);
print fill($initial_tab, $subsequent_tab, @text);
$lines = wrap($initial_tab, $subsequent_tab, @text);
@paragraphs = fill($initial_tab, $subsequent_tab, @text);
Example 2
use Text::Wrap qw(wrap $columns $huge);
$columns = 132; # Wrap at 132 characters
$huge = 'die';
$huge = 'wrap';
$huge = 'overflow';
Example 3
use Text::Wrap;
$Text::Wrap::columns = 72;
print wrap('', '', @text);
DESCRIPTION
"Text::Wrap::wrap()" is a very simple paragraph formatter. It formats a single paragraph at a time by breaking lines at word boundaries.
Indentation is controlled for the first line ($initial_tab) and all subsequent lines ($subsequent_tab) independently. Please note:
$initial_tab and $subsequent_tab are the literal strings that will be used: it is unlikely you would want to pass in a number.
Text::Wrap::fill() is a simple multi-paragraph formatter. It formats each paragraph separately and then joins them together when it's
done. It will destroy any whitespace in the original text. It breaks text into paragraphs by looking for whitespace after a newline. In
other respects it acts like wrap().
Both "wrap()" and "fill()" return a single string.
OVERRIDES
"Text::Wrap::wrap()" has a number of variables that control its behavior. Because other modules might be using "Text::Wrap::wrap()" it is
suggested that you leave these variables alone! If you can't do that, then use "local($Text::Wrap::VARIABLE) = YOURVALUE" when you change
the values so that the original value is restored. This "local()" trick will not work if you import the variable into your own namespace.
Lines are wrapped at $Text::Wrap::columns columns (default value: 76). $Text::Wrap::columns should be set to the full width of your output
device. In fact, every resulting line will have length of no more than "$columns - 1".
It is possible to control which characters terminate words by modifying $Text::Wrap::break. Set this to a string such as '[s:]' (to break
before spaces or colons) or a pre-compiled regexp such as "qr/[s']/" (to break before spaces or apostrophes). The default is simply 's';
that is, words are terminated by spaces. (This means, among other things, that trailing punctuation such as full stops or commas stay
with the word they are "attached" to.) Setting $Text::Wrap::break to a regular expression that doesn't eat any characters (perhaps just a
forward look-ahead assertion) will cause warnings.
Beginner note: In example 2, above $columns is imported into the local namespace, and set locally. In example 3, $Text::Wrap::columns is
set in its own namespace without importing it.
"Text::Wrap::wrap()" starts its work by expanding all the tabs in its input into spaces. The last thing it does it to turn spaces back
into tabs. If you do not want tabs in your results, set $Text::Wrap::unexpand to a false value. Likewise if you do not want to use
8-character tabstops, set $Text::Wrap::tabstop to the number of characters you do want for your tabstops.
If you want to separate your lines with something other than "
" then set $Text::Wrap::separator to your preference. This replaces all
newlines with $Text::Wrap::separator. If you just want to preserve existing newlines but add new breaks with something else, set
$Text::Wrap::separator2 instead.
When words that are longer than $columns are encountered, they are broken up. "wrap()" adds a "
" at column $columns. This behavior can
be overridden by setting $huge to 'die' or to 'overflow'. When set to 'die', large words will cause "die()" to be called. When set to
'overflow', large words will be left intact.
Historical notes: 'die' used to be the default value of $huge. Now, 'wrap' is the default value.
EXAMPLES
Code:
print wrap(" ","",<<END);
This is a bit of text that forms
a normal book-style indented paragraph
END
Result:
" This is a bit of text that forms
a normal book-style indented paragraph
"
Code:
$Text::Wrap::columns=20;
$Text::Wrap::separator="|";
print wrap("","","This is a bit of text that forms a normal book-style paragraph");
Result:
"This is a bit of|text that forms a|normal book-style|paragraph"
