If more than one name is specified in the file parameter, the grep command displays the name of the file that contains the matching row. Characters with special meaning to the shell ($, *, [, |, ^, (,), \) must be enclosed in double quotation marks when appearing in the pattern parameter. If the pattern parameter is not a simple string,

it has a disadvantage is that the tag is relatively small, only fixed set of tags such as XML combines the advantages of SGML and HTML and eliminates its drawbacks. XML is still considered to be an SGML language. Simpler than SGML, but most of the functionality of SGML can be achieved. In the summer of 1996, John Bosak of Sun Microssystem began developing the SGML workgroup (now called an XML workgroup). Their goal is to create a SGML that enables it to take advantage of SGML and preserve the s
