7 million lines should not be too bad. code #2 is storing all those lines in one variable, but if you are on a production system, you should be ok.

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 for-
matted 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.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWcsu |
+-----------------------------+-----------------------------+
SEE ALSO
nroff(1), vi(1), attributes(5), environ(5)
NOTES
The -width option is acceptable for BSD compatibility, but it may go away in future releases.
