Filtering show Command Output
Output from the show commands can generate a large amount of data. To display only a subset of
information, type the Pipe character (|) followed by a keyword (begin, include, exclude, or file) and a
regular expression.
Table 5-3 shows the filtering options for the show command.
In the following example, the show interface command includes only lines in which the expression
“protocol” appears:
RP/0/RSP0/CPU0:router# show interface | include protocol
Null0 is up, line protocol is up
0 drops for unrecognized upper-level protocol
