![]() Therefore, to replace every occurrence of the string “disinformation” with “newspeak,” type: You can use all the special matching characters for searches in search-and-replace. The procedure for replacing a text string is based on the search procedures that are discussed previously. For example, to find all strings beginning with a through z and ending with “isinformation” and to find all occurrences of the string “isinformation”, type: You can effectively combine brackets and the asterisk to look for well-defined alternatives. To match zero or more occurrences of the last character, type an asterisk ( *) in the string. The search pattern / stringfinds strings that begin with either “m” or “d.” Conversely, / string finds strings that begin with any letter from “d” through “m.” To search for alternative characters in a string, enclose the alternatives in brackets. For example, to find the next occurrence of “disinformation” or “misinformation,” type:īecause this is a search for a string and not a word, this search pattern might also find such constructions as “misinformationalist” and “disinformationism.” ) in the string at the location to be matched. For example, to find the next occurrence of the word-as opposed to the string-“search”, type: Thus, to match a word, rather than a string, combine the end-of-word and beginning-of-word tags in the search pattern. To match the beginning of a word, type \ at the end of the string. Note that the period is escaped with a backslash. For example, to find the next line ending with “search.”, type: To match the end of a line, end the search string with a dollar sign ( $). For example, to find the next line beginning with “Search”, type: To match the beginning of a line, start the search string with a caret ( ^). You can make searches more precise by tagging the string with indicators for the following characteristics: If you want to search for a string that includes one or more of these characters, you must precede the special character with a backslash. You can use these special characters as commands to the search function. For example, to search for the string “anything?” type /anything\? and press Return. To escape a special character, precede it with a backslash ( \). ^ * $ \ ?) have special significance to the search process and must be “escaped” when they are used in a search. If the string is not found, vi displays Pattern not found on the last line of the screen.Ĭertain special characters ( /
