You can use special characters to construct complex regular expressions. See the next section for information on special characters used with regular expressions. Using special characters in regular expressions You use a regular expression to specify a single character or multiple characters as a search string. In addition, you can include special characters that influence the way the software matches the output against the search string. These special characters are listed in the following table. TABLE 29 Character Special characters for regular expressions Operation . The period matches on any single character, including a blank space. For example, the following regular expression matches "aaz", "abz", "acz", and so on, but not just "az": a.z * The asterisk matches on zero or more sequential instances of a pattern. For example, the following regular expression matches output that contains the string "abc", followed by zero or more Xs: abcX* + The plus sign matches on one or more sequential instances of a pattern. For example, the following regular expression matches output that contains "de", followed by a sequence of "g"s, such as "deg", "degg", "deggg", and so on: deg+ ? The question mark matches on zero occurrences or one occurrence of a pattern. For example, the following regular expression matches output that contains "dg" or "deg": de?g NOTE: Normally when you type a question mark, the CLI lists the commands or options at that CLI level that begin with the character or string you entered. However, if you enter Ctrl-V and then type a question mark, the question mark is inserted into the command line, allowing you to use it as part of a regular expression. 22 BigIron RX Series Configuration Guide 53-1001810-01
