Pipe/Count
The SR OS supports a pipe/count command (...| count) that provides a count of the number
of lines that would have otherwise been displayed. The pipe/count command is particularly
useful when used in conjunction with the pipe/match command in order to count the number
of output lines that match a specified pattern.
For example:
*A:dut-c# show service service-using vprn
===============================================================================
Services [vprn]
