Table 3-3 Show Command Filter Options
Command
show command | begin regular-expression
show command | exclude regular-expression
show command | include regular-expression
show command | file disk0:myconfigfile
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

If a filter is specified at the original command or at a 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
