Page 29 Chapter1 Command-Line Interface Using the CLI String Search You can create a multiple-character regular expression containing all letters, all digits, all keyboard characters, or a combination of letters, digits, and other keyboard characters. These examples are all valid regular expressions: telebit 3107 v32bis Multipliers You can create more complex regular expressions to match multiple occurrences of a specified regular...
Page 30 Chapter1 Command-Line Interface Using the CLI String Search Anchoring You can match a regular expression pattern against the beginning or the end of the string. That is, you can specify that the beginning or end of a string contains a specific pattern. You “anchor” these regular expressions to a portion of the string using the special characters shown in Table1-6 Table1-6...
Page 31: Saving Configuration Changes
Chapter1 Command-Line Interface Saving Configuration Changes This regular expression uses parentheses for recall: a(.)bc(.)\1\2 This regular expression matches an a followed by any character (call it character 1), followed by bc followed by any character (character 2), followed by character 1 again, followed by character 2 again. So, the regular expression can match aZbcTZT.
