I think you can simplify that awk code by telling it to use all whitespace as record separators. One statement instead of four. Then you just tell it to process the "odd" lines -- 1, 3, 5, ...

You can get rid of the BEGIN block by feeding variables into awk on the commandline. This also lets you script the value of the outputfile.

I started adding pipes and stuff then saw the BINMODE, and realized that's probably why you were forced to use temp files. Oh well.

Code:

awk --characters-as-bytes 'NR%2 { printf("%c", ($1+32768)/256)) > OUT }' RS="[ \r\n\t]+" BINMODE=3 OUT="/tmp/leftbinary" /tmp/signed16bit.txt

NAME

       ldm - a display manager for LTSP

SYNOPSIS

       ldm <vt[1-N]> <:[0-N]>

DESCRIPTION

       ldm(1)  starts an X server and presents the user with a login screen, similar to the gdm(1) login prompt. instead of using the XDMCP proto-
       col, ldm(1) uses ssh(1) connect to remote servers, then starts an Xsession either via ssh(1) X forwarding, or direct TCP/IP connection.

       It was designed for the LTSP project, but could be used in a non-ltsp environment as well.
