Thanks pilnet101 . Basically it increases the line length by 2 every line and memorizes the line. Then at maximum length, the loop starts to decrement, rather than increment and only prints the lines memorized in the increment phase.
With regards to the setting of the quotient q and the line n where the maximum line length occurs, and using the name m for maximum line length rather than l which is easily confused with the number 1), perhaps this is a bit clearer:

The histogram scale is logaritmic, to avoid very short bars for smaller files or very long bars for bigger files.

I know that when using 'while (<FILE>) {}', Perl reads only one line of the file at one time, and store it in '$_'.
Can I change some parameters so that 'while (<>) {}' can read more than one lines, like 2 or 5 lines at one time?
Thanks for the help! (1 Reply)

hxnormalize
HXNORMALIZE(1) HTML-XML-utils HXNORMALIZE(1)NAME
hxnormalize - pretty-print an HTML file
SYNOPSIS
hxnormalize [ -x ] [ -e ] [ -d ] [ -s ] [ -L ] [ -i indent ] [ -l line-length ] [ -c commentmagic ] [ file-or-URL ]
DESCRIPTION
The hxnormalize command pretty-prints an HTML file, and also tries to fix small errors. The output is the same HTML, but with a maximum
line length and with optional indentation to indicate the nesting level of each line.
OPTIONS
The following options are supported:
-x Use XML conventions: empty elements are written with a slash at the end: <IMG />. Implies -e.
-e Always insert endtags, even if HTML does not require them (for example: </p> and </li>).
-d Omit the DOCTYPE from the output.
-i indent Set the number of spaces to indent each nesting level. Default is 2. Not all elements cause an indent. In general, elements that
can occur in a block environment are started on a new line and cause an indent, but inline elements, such as EM and SPAN do not
cause an indent.
-l line-length
Sets the maximum length of lines. hxnormalize will wrap lines so that all lines are as long as possible, but no longer than this
length. Default is 72. Words that are longer than the line length will not be broken, and will extend past this length. A
content of the STYLE, SCRIPT and PRE elements will not be line-wrapped.
-s Omit <span> tags that don't have any attributes.
-L Remove redundant "lang" and "xml:lang" attributes. (I.e., those whose value is the same as the language inherited from the parent
element.)
-c commentmagic
Comments are normally placed right after the preceding text. That is usually correct for short comments, but some comments are
meant to be on a separate line. commentmagic is a string and when that string occurs inside a comment, hxnormalize will output
an empty line before that comment. E.g. -c "====" can be used to put all comments that contain "====" on a separate line, pre-
ceded by an empty line. By default, no comments are treated that way.
OPERANDS
The following operand is supported:
file-or-URL
The name or URL of an HTML file. If absent, standard input is read instead.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
> 0 An error occurred in the parsing of the HTML file. hxnormalize will try to correct the error and produce output anyway.
ENVIRONMENT
To use a proxy to retrieve remote files, set the environment variables http_proxy and ftp_proxy. E.g., http_proxy="http://localhost:8080/"
BUGS
The error recovery for incorrect HTML is primitive.
hxnormalize will not omit an endtag if the white space after it could possibly be significant. E.g., it will not remove the first </p> from
"<div><p>text</p> <p>text</p></div>".
hxnormalize can currently only retrieve remote files over HTTP. It doesn't handle password-protected files, nor files whose content depends
on HTTP "cookies."
