Since the date data in the file is in the correct order (most significant data comes first in the string) and the fields (year, month, day, hour, minute, and second) are all fixed length fields, the gsub()calls can be avoided if the system date is formatted the same way the dates are formatted in the file:
Code:
awk -F, '$16 > sys' sys="$(date +'%Y%m%d %H:%M:%S')" infile

or, if the GNU time extensions are in your version of awk,
Code:
awk -F, 'BEGIN{sys = strftime("%Y%m%d %H:%M:%S")} $16 > sys' infile

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
