FILTERING OUTPUT
The output from commands can in most cases be filtered to limit the output to only those lines that
match/trigger a specific string. The available filtering is:
Begin – display the first line that begins with the matching string and all subsequent lines
Include – display only those lines that match
Exclude – display only those lines that do not match
The filter is added at the end of the command and its parameters; the | character marks the beginning of
the filter. The <string> parameter is case-sensitive and can specify any item in the output line. The
syntax is:
<command> | { begin | include | exclude } <string>
