In addition to the suggestion Scrutinizer provided, note that the command in post #1 in this thread:
Code:
 awk '$3="XYX"' FS=, OFS='|' filename.txt

produces the output:
Code:
> BRYAN BAKER|4/4/2015|518 VIRGINIA AVE|TEST||XYX
> JOE BAXTER|3/30/2015|2233 MockingBird RD|ROW2||XYX

Your input field separator is |; not ,. So, setting FS=, probably isn't what you want for this input file. Since there are no commas in your input file, setting field 3 creates an empty field and adds another field with the contents you specified.

Setting $3 to the string XYX will never replace column 3 with XYZ.

irsend - basic LIRC program to send infra-red commands SYNOPSIS
irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
