A possible solution :
Code:
eval $(
   ls -rd V??R?? | \
   awk '
   NR==1 { 
      current = $1; 
      base    = "";
      cversion = substr($1, 2, 2);
      next
   }
   { 
      version = substr($1, 2, 2);
      if (version == cversion) {
         if (base == "") base = $1;
      } else  {
         base = $1;
         exit;
     }
   }
   END {
      print "current=" current;
      print    "base=" base;
   }
   '
)

echo "Current = $current"
echo "Base    = $base"

Directories list:
Code:
$ ls -d V??R??
V00R00  V00R01  V00R11  V00R12  V01R00  V01R01  V02R00  V02R01  V02R03

Output:
Code:
Current = V02R03
Base    = V01R01

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
