Back Forward Regular expression

A regular expression is a symbolic representation of a pattern of text. Regular expressions are widely used in UNIX text search facilities such as the grep command.

XXXXXXXXXXXXXXXXXXX UPDATE TO MENTION REGULAR EXPRESSION RULE V6.1SP2 XXXXX

For example, the regular expression

[A-Z0-9._%-]++@[A-Z0-9._%-]+\.[A-Z]{2,4}

matches [email protected] and many other email addresses.

Applications

Notes

Support of these facilities is based on the Sun Microsystems implementation of regular expressions (java.util.regex.Pattern).
