text processing utility การใช้

• These expressions may be used to describe advanced search patterns in " find and replace "-like operations of text processing utilities.
• For instance, text processing utilities use regular expressions to describe advanced search patterns, but NFAs are better suited for execution on a computer.
• Regular expressions are used in search engines, search and replace dialogs of word processors and text editors, in text processing utilities such as sed and AWK and in lexical analysis.
• A separate port of the up-to-date Debian utilities was started in 2007, but apparently abandoned in 2009 . Several of the text processing utilities in SUA ( e . g . awk ) are not compatible with Unicode or wide character text files.
