Code:
Fred Fardbarkle:674-843-1385:20 Parak Lane, Duluth, MN 23850:4/12/23:780CR***LF

Which get printed as:
Code:
***d Fardbarkle:674-843-1385:20 Parak Lane, Duluth, MN 23850:4/12/23:780900

This is why
Code:
sed '/^Fred/s/.$/***/' inputfile

does indeed work because then you delete the CR (the "." takes care of it) , so your sentence becomes:
Code:
Fred Fardbarkle:674-843-1385:20 Parak Lane, Duluth, MN 23850:4/12/23:780***LF

So I think you should convert the file to unix format first and then the original sed statement should work.
Right on the money. That was exactly the problem. I simply copied the contents of the file, created a new one in emacs and pasted it in there, and then renamed it to the original. Then all of a sudden it started to work. Thanks.

There are things you know, and things you know you don't know, and then there's things you don't know you don't know. That was something I didn't know I didn't know. God that was frustrating. To know your code is correct, but then it doesn't work is probably one of the worst part of this profession.

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
