Looks like you are using the gsub function incorrectly in your awk statement. I feel sed would be the best tool for this job.

Assuming you want your output to look like this (if this is not what you want your output to look like please provide sample output):

Code:
1 Ps 1 ,1 VWB/(J VWB VWB
2 Ps 1 ,1 &WHJ== WHJ HJ==
3 Ps 1 ,1 L L L
4 Ps 1 ,1 GBR/~> GBR> GBR
5 Ps 1 ,1 D D D

You can use the below sed one liner which will work on your input:

Code:
 sed 's/\([0-9]\),/\1 ,/g'  textfile

Reading your post again, it looks like you want your output like this instead:

Code:
1 Ps 1,1  VWB/(J VWB VWB
2 Ps 1,1  &WHJ== WHJ HJ==
3 Ps 1,1  L L L
4 Ps 1,1  GBR/~> GBR> GBR
5 Ps 1,1  D D D

In which case change the sed one liner to this:

Code:
sed 's/\(,[0-9]\)/\1 /g' textfile

NAME
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
