Java File name extensions

Hello people, I was wondering if anyone could help me?

I want to produce a shell script that changes the filename extension on all matching file.

E.G. change all files called ‘something.rtf' to ‘something.doc' by giving the command:


Changex rtf doc

*where ‘Changex' is the name of my shell script.

Does anyone know how to do this or know what ‘functions' I should use???

with regards,
nick

TEXTUTIL(1)						    BSD General Commands Manual 					       TEXTUTIL(1)

NAME
textutil -- text utility SYNOPSIS
textutil [command_option] [other_options] file ... DESCRIPTION
textutil can be used to manipulate text files of various formats, using the mechanisms provided by the Cocoa text system. The first argument indicates the operation to perform, one of: -help Show the usage information for the command and exit. This is the default command option if none is specified. -info Display information about the specified files. -convert fmt Convert the specified files to the indicated format and write each one back to the file system. -cat fmt Read the specified files, concatenate them, and write the result out as a single file in the indicated format. fmt is one of: txt, html, rtf, rtfd, doc, docx, wordml, odt, or webarchive There are some additional options for general use: -extension ext Specify an extension to be used for output files (by default, the extension will be determined from the format). -output path Specify the file name to be used for the first output file. -stdin Specify that input should be read from stdin rather than from files. -stdout Specify that the first output file should go to stdout. -encoding IANA_name | NSStringEncoding Specify the encoding to be used for plain text or HTML output files (by default, the output encoding will be UTF-8). NSStringEncoding refers to one of the numeric values recognized by NSString. IANA_name refers to an IANA character set name as understood by CFString. The operation will fail if the file cannot be converted to the specified encoding. -inputencoding IANA_name | NSStringEncoding Force all plain text input files to be interpreted using the specified encoding (by default, a file's encoding will be deter- mined from its BOM). The operation will fail if the file cannot be interpreted using the specified encoding. -format fmt Force all input files to be interpreted using the indicated format (by default, a file's format will be determined from its contents). -font font Specify the name of the font to be used for converting plain to rich text. -fontsize size Specify the size in points of the font to be used for converting plain to rich text. -- Specify that all further arguments are file names. There are some additional options for HTML and WebArchive files: -noload Do not load subsidiary resources. -nostore Do not write out subsidiary resources. -baseurl url Specify a base URL to be used for relative URLs. -timeout t Specify the time in seconds to wait for resources to load. -textsizemultiplier x Specify a numeric factor by which to multiply font sizes. -excludedelements (tag1, tag2, ...) Specify which HTML elements should not be used in generated HTML (the list should be a single argument, and so will usually need to be quoted in a shell context). -prefixspaces n Specify the number of spaces by which to indent nested elements in generated HTML (default is 2). There are some additional options for treating metadata: -strip Do not copy metadata from input files to output files. -title val Specify the title metadata attribute for output files. -author val Specify the author metadata attribute for output files. -subject val Specify the subject metadata attribute for output files. -keywords (val1, val2, ...) Specify the keywords metadata attribute for output files (the list should be a single argument, and so will usually need to be quoted in a shell context). -comment val Specify the comment metadata attribute for output files. -editor val Specify the editor metadata attribute for output files. -company val Specify the company metadata attribute for output files. -creationtime yyyy-mm-ddThh:mm:ssZ Specify the creation time metadata attribute for output files. -modificationtime yyyy-mm-ddThh:mm:ssZ Specify the modification time metadata attribute for output files. EXAMPLES
textutil -info foo.rtf displays information about foo.rtf. textutil -convert html foo.rtf converts foo.rtf into foo.html. textutil -convert rtf -font Times -fontsize 10 foo.txt converts foo.txt into foo.rtf, using Times 10 for the font. textutil -cat html -title "Several Files" -output index.html *.rtf loads all RTF files in the current directory, concatenates their contents, and writes the result out as index.html with the HTML title set to "Several Files". DIAGNOSTICS
The textutil command exits 0 on success, and 1 on failure. CAUTIONS
Some options may require a connection to the window server. HISTORY
The textutil command first appeared in Mac OS X 10.4. Mac OS X September 9, 2004 Mac OS X
