Displaying System Information with show Commands
Table 6-3 show Command Filter Options
In the following example, the show interface command includes only lines in which the expression
“protocol” appears:
RP/0/RP0/CPU0:router# show interface | include protocol
Null0 is up, line protocol is up
0 drops for unrecognized upper-level protocol
POS0/2/0/0 is administratively down, line protocol is administratively down
0 drops for unrecognized upper-level protocol
POS0/2/0/1 is administratively down, line protocol is administratively down
0 drops for unrecognized upper-level protocol
POS0/2/0/2 is administratively down, line protocol is administratively down
0 drops for unrecognized upper-level protocol
POS0/2/0/3 is administratively down, line protocol is administratively down
0 drops for unrecognized upper-level protocol
MgmtEthernet0/RP0/CPU0/0 is administratively down, line protocol is administratively
down
MgmtEthernet0/RP0/CPU0/0 is administratively down, line protocol is administratively
down
0 drops for unrecognized upper-level protocol
Note Filtering is available for submodes, complete commands, and anywhere that <cr> appears in the “?”
output.
Adding a Filter at the --More-- Prompt
You can specify a filter at the --More-- prompt of a show command output by entering a forward slash
(/) followed by a regular expression. The filter remains active until the command output finishes or is
interrupted (using Ctrl-Z or Ctrl-C). The following rules apply to this technique:
• If a filter is specified at the original command or previous --More-- prompt, a second filter cannot
be applied.
• The use of the keyword begin does not constitute a filter.
• The minus sign (–) preceding a regular expression displays output lines that do not contain the
regular expression.
• The plus sign (+) preceding a regular expression displays output lines that contain the regular
expression.
In the following example, the user adds a filter at the
--More-- prompt to show only the lines in the
remaining output that contain the regular expression “ip.”
RP/0/RP0/CPU0:router# show configuration running | begin line
Building configuration...
line console
