My friend me through Mac's "Terminal" you can create and program your own applications by just using the UNIX codes and just in Terminal. Is this true? If it is not, what kind of program or application would I need to make any kind of application?

Thanks in advance. Smilie

A little advice from someone who owned two OS X-capable Macs and used all the powerful extras he could on both:

OS X Developer Tools, free from Apple (you just have to sign up to their Developer Community, also free) enhances what Terminal can do in terms of compiling and testing programs created with its own resident utilities. Apple's X11 extends those bounds considerably more. If you bought your Mac new or refurb from an authorized Apple reseller, CDs with those packages on them should have come with it. If not, and your Mac happens to burn CDs/DVDs (most do nowadays), then you can download the necessary disk images direct from Apple. Just Google for Developer Tools for Leopard and Mac OS X X11 for Leopard, and look for links where the URLs happen to have either "www.apple.com" or "developer.apple.com" at the beginning.

Twelve years of Mac home use comes in handy sometimes.

opendiff

opendiff(1)						    BSD General Commands Manual 					       opendiff(1)

NAME

     opendiff -- Use FileMerge to graphically compare or merge file or directories

SYNOPSIS

     opendiff file1 file2 [-ancestor ancestorFile] [-merge mergeFile]
     opendiff dir1 dir2 [-ancestor ancestorDirectory] [-merge mergeDirectory]

DESCRIPTION

     opendiff is a command line utility that provides a convenient way to launch the FileMerge application from Terminal to graphically compare
     files or directories.  If FileMerge is already running, opendiff will connect to that running instance for the new comparison.  opendiff
     exits immediately after the comparison request has been sent to FileMerge.

     opendiff and FileMerge can be used to compare two files file1 and file2 or to compare two directories dir1 and dir2.

     If the -ancestor flag is given, FileMerge will compare the two files or directories to a common ancestor.	This is useful if two people inde-
     pendently modify copies of a single original file or directory.

     FileMerge lets you merge two files or directories together to create a third file or directory.  To see the contents of a merged file, drag
     the splitter bar at the bottom of FileMerge's file comparison window.  The contents of the merged file can be directly edited within File-
     Merge.  After editing, the merged file can be saved to the file (or into the directory) specified with the Fl merge flag.	If a destination
     is not specified with the -merge flag, FileMerge will ask for a destination file or directory when you try to save a merged file.

     For further information, please consult the Help information available from the FileMerge application.

FILES

     /Developer/Applications/Utilities/FileMerge.app

     opendiff and FileMerge are installed as part of the Mac OS X Developer Tools.
