Oh dear, my last post missed the "multiple occurrences" requirement.
Another variant of the sed solution
Code:
count=$(hive --orcfiledump /hdfs_path/ | sed -n '/^ *Rows: */{;s///;s/ .*//;p;q;}')

With awk
Code:
count=$(hive --orcfiledump /hdfs_path/ | awk '$1=="Rows:"/{print $2; exit}')

A pure shell variant
Code:
while
  read X count Y &&
  [ "$X" != "Rows:" ]
do
  :
done < <(hive --orcfiledump /hdfs_path/)

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
