The most common ways to use the pipe (|) symbol is to constrain the output
using match, except, find, or last:

• ✓ | match: Specifies exactly what you want to display:
  wiley@netnik > show configuration | match at-
2/1/0 {
at-2/1/1 {
at-2/2/0 {
at-5/2/0 {
at-5/3/0 {

• ✓ | except: Displays output that ignores a specific string:
  
wiley@netnik> show system users | except root
8:28PM up 1 day, 13:59, 2 users, load averages:
0.01, 0.01, 0.00
USER TTY FROM LOGIN@ IDLE WHAT
wiley.netnik 7:25PM - cli

• ✓ | find: Displays output starting at the first occurrence of the matching
  text:
  
wiley@netnik> show ethernet-switching interfaces detail | find “Index: 80”
Interface: ge-0/0/16.0 Index: 80

• ✓ | last: Displays only the last screen of the listing:
  
wiley@netnik> show ethernet-switching interfaces detail | last
Interface: ge-0/0/16.0 Index: 80
