Internet Packet Exchange (IPX)

The IPX grep facility actually implements a modified subset of the egrep
regular expression syntax. Table 4 lists the pattern-matching characters
that are implemented.
Important
Considerations
■
The
ipx route display
option searches on the route address only,
not on everything in the route database.
■
The
ipx server display
option searches on the service name only,
not on everything in the service database. Therefore, you cannot enter
a regular expression for the service type, even though the prompt
looks identical.
■
The search is not case sensitive.
■
Single or double quotation marks have no special meaning. They are
simply included as part of the search string. If the command line
parser encounters a blank, it stops parsing.
Table 4 IPX Grep Regular Expression Pattern-Matching Characters
Pattern
Character
Meaning
*
Match any number (or none) of the single character that immediately
precedes it. The preceding character can be a regular expression.
.
Match any single character.
^
Match the following regular expression at the beginning of a word.
$
Match the following regular expression at the end of a word.
[]
Match any one of the enclosed characters.
■
A hyphen (-) indicates a range of consecutive characters. For
example:
[a-z]
matches any letter.
■
A caret (^) as the first character in the brackets reverses the sense. It
matches any one character not in the list. For example:
[^a-z]
matches any character that is not a letter.
\
Turn off the special meaning of the character that follows.
+
Match one or more instances of the preceding regular expression.
?
Match zero or one instance of the preceding regular expression.
