To be honest i don't quite get what you are trying to achieve: you take 2000 lines of some text and concatenate this to one big line, separated by "|". (Small wonder, the line exceeds 3000 characters.)

You have omitted the awk script itself, so i can't say what it does and how it could be changed to work on the normal file, but maybe you could rearrange the pipeline so that "awk" comes before "paste"?

I'd like to warn you: using "gawk" or any other non-standard tool will maybe limit the usability of your script to a certain platform and/or certain system. It is usually better to limit oneself to the resources the system offers without any non-standard tool. This is similar to using non-ANSI C constructs in programming: you pay the price with very complicated porting process sooner or later.

I hope this helps.

NAME
paste -- merge corresponding or subsequent lines of files SYNOPSIS
paste [-s] [-d list] file ... DESCRIPTION
The paste utility concatenates the corresponding lines of the given input files, replacing all but the last file's newline characters with a single tab character, and writes the resulting lines to standard output. If end-of-file is reached on an input file while other input files still contain data, the file is treated as if it were an endless source of empty lines. The options are as follows: -d list Use one or more of the provided characters to replace the newline characters instead of the default tab. The characters in list are used circularly, i.e., when list is exhausted the first character from list is reused. This continues until a line from the last input file (in default operation) or the last line in each file (using the -s option) is displayed, at which time paste begins selecting characters from the beginning of list again. The following special characters can also be used in list: newline character tab character \ backslash character Empty string (not a null character). Any other character preceded by a backslash is equivalent to the character itself. -s Concatenate all of the lines of each separate input file in command line order. The newline character of every line except the last line in each input file is replaced with the tab character, unless otherwise specified by the -d option. If '-' is specified for one or more of the input files, the standard input is used; standard input is read one line at a time, circularly, for each instance of '-'. The paste utility exits 0 on success, and >0 if an error occurs. SEE ALSO
cut(1) STANDARDS
The paste utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible. BSD
