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/)

NAME
incr - Increment the value of a variable SYNOPSIS
incr varName ?increment? _________________________________________________________________ DESCRIPTION
Increments the value stored in the variable whose name is varName. The value of the variable must be an integer. If increment is supplied then its value (which must be an integer) is added to the value of variable varName; otherwise 1 is added to varName. The new value is stored as a decimal string in variable varName and also returned as result. Starting with the Tcl 8.5 release, the variable varName passed to incr may be unset, and in that case, it will be set to the value incre- | ment or to the default increment value of 1. EXAMPLES
Add one to the contents of the variable x: incr x Add 42 to the contents of the variable x: incr x 42 Add the contents of the variable y to the contents of the variable x: incr x $y Add nothing at all to the variable x (often useful for checking whether an argument to a procedure is actually integral and generating an error if it is not): incr x 0 SEE ALSO
