From an excerption of the gawk manual:
Quote:
split(string, array [, fieldsep])
This function divides string into pieces separated by fieldsep and stores the pieces in array. The first piece is stored in array[1], the second piece in array[2], and so forth. The string value of the third argument, fieldsep, is a regexp describing where to split string (much as FS can be a regexp describing where to split input records). If fieldsep is omitted, the value of FS is used. split returns the number of elements created.

In my first attempt, I was using grep to find a list from file.1 within another file, file.2 which I then needed to paste the output from file.3 to file.1 in the same order. However, the results weren't what I wanted.

split
SPLIT(1) BSD General Commands Manual SPLIT(1)
NAME
split -- split a file into pieces
SYNOPSIS
split [-a suffix_length] [-b byte_count[k|m]] [-l line_count] [-p pattern] [file [name]]
DESCRIPTION
The split utility reads the given file and breaks it up into files of 1000 lines each. If file is a single dash ('-') or absent, split reads
from the standard input.
The options are as follows:
-a Use suffix_length letters to form the suffix of the file name.
-b Create smaller files byte_count bytes in length. If ``k'' is appended to the number, the file is split into byte_count kilobyte
pieces. If ``m'' is appended to the number, the file is split into byte_count megabyte pieces.
-l Create smaller files n lines in length.
-p pattern
The file is split whenever an input line matches pattern, which is interpreted as an extended regular expression. The matching line
will be the first line of the next output file. This option is incompatible with the -b and -l options.
If additional arguments are specified, the first is used as the name of the input file which is to be split. If a second additional argument
is specified, it is used as a prefix for the names of the files into which the file is split. In this case, each file into which the file is
split is named by the prefix followed by a lexically ordered suffix using suffix_length characters in the range ``a-z''. If -a is not speci-
fied, two letters are used as the suffix.
If the name argument is not specified, the file is split into lexically ordered files named with prefixes in the range of ``x-z'' and with
suffixes as above.
SEE ALSO
csplit(1), re_format(7)
STANDARDS
The split utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
A split command appeared in Version 3 AT&T UNIX.
BUGS
For historical reasons, if you specify name, split can only create 676 separate files. The default naming convention allows 2028 separate
files. The -a option can be used to work around this limitation.
The maximum line length for matching patterns is 65536.
