Those commands are trying to load the entire line into memory at once, which won't work on a 64 32-bit system since there's a 4GB limit on per-process memory and sufficient clutter in the way that you probably can't get an entire 2.5G in one chunk.

How big are the individual records? You can tell awk to use things other than \n as a record separator, changing its definition of lines:

Code:
$  awk -v RS='\\*end\\*' '1' < data
RANDOMDATA
RANDOMDATA
RANDOMDATA
RANDOMDATA
$

Use nawk or gawk if you have it.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
