Below are some more information in using the above pipe character in Exos:
In ExtremeXOS software, the resulting command is as follows:show | {include | exclude | begin}
----show State the command. For example: show ports. (This is
followed by the vertical bar (|) when used as the pipe
character.)
----include Display the lines that match the regular expression.
----exclude Do not display the lines that match the regular expression.
----begin Display all the lines starting with the first line that matches
the regular expression.
----regexp The regular expression to match.
• Regular expressions are case-sensitive.
• Special characters in regular expressions such as [ ], ?,
and * have special significance to the Linux shell and it is
therefore common to specify your regular expression in
quotes to protect it from the shell.
