How to search a string using a basic regular expression in Vi editor? How about using extended regular expression in Vi editor?
Homework Answers
Using Basic Regular Expression
If you want to search a string starting with "no" and ending with "on"
Press / to search string one by one
and then regular expression no.*on
where . denotes any character but not end of line(EOL)
and * denotes repetition on previously occured characters
Press enter to mve cursor to the found string
Press n to find next occurence.
OUTPUT:
Using Extended Regular Expression
Use :set to enable use of extended regular expression in vi editor
This can be used as extended regular expression
:%s/v([0-9])/
0-9 is used to find numbers in expression
v is used so that there is no need to write ( or ) and simple ( or ) and be typed

Hi, What is in your opinion in this message related to Vi Text Editor? I have never used a vi text editor before. I have always used word processors like Microsoft Word or notepad. It was very interesting to learn the basics of a text editor and learn that you can make a file right from that by using a couple of commands. I believe I would be able to use the text editor in the work field but I...

Regular Expression processor in Java Overview: Create a Java program that will accept a regular expression and a filename for a text file. The program will process the file, looking at every line to find matches for the regular expression and display them. Regular Expression Format The following operators are required to be accepted: + - one or more of the following character (no groups) * - zero or more of the following character (no groups) [] – no negation,...

Write a PHP regular expression pattern that matches a string that satisfies the following description: The string must begin with the (uppercase) letter A. Any three alphanumeric characters must follow. After these, the letter B (uppercase or lowercase) must be repeated one or more times, and the string must end with two digits.

4. A regular expression for the language over the alphabet fa, b) with each string having an even number of a's is (b*ab*ab*)*b*. Use this result to find regular expressions for the following languages a language over the same alphabet but with each string having odd number of a's.

Write a regular expression that captures the set of strings composed of 'a', 'b', and 'c', where any string uses at most two of the three letters (for example, "abbab" is a valid string, or "bccbb", or "ccacaa", but not "abccba": strings that contain only one of the three letters are also fine). Give a non-deterministic finite automaton that captures the regular expression from Using the construction described in class, give a deterministic version of the automaton. Repeat the previous...
