Linux vi C make Primer Tutorial<\/p><\/div>\n

The Linux (or unix) command vi<\/i><\/a> is a powerful command line editor tool which has a long history with unix and the maintenance of C code (as just one example of its uses).<\/p>\n

So much so, as far as C coding goes, that the creators of vi<\/i> clearly thought you may “set up shop” in the vi<\/i> world, because, if you have a makefile, like our simple one<\/a> for today’s tutorial, you can use vi<\/i>‘s :make<\/i> command to compile your C or C++ code while in vi<\/i> … for those thinking that they never “make” syntax errors in C … hope you know where all the Kryptonite<\/a> supplies are?<\/p>\n

You’ll notice that you can run that compiled code (if successful) and still not leave vi<\/i> via :!.\/Hello<\/i> (where the ! is taking you to the parent shell).<\/p>\n

There are other text editors for command line Linux (or unix), some being pico<\/a> and emacs<\/a>, and there is a bigger version of vi called vim<\/a>.<\/p>\n

The thing about a lot of command line text editors is that they look unfriendly (it’s less unfriendly if you know {ESC}: gets you to the : prompt from the screen view … second green arrow in tutorial picture included this), and that can be true, and this has lead me to do more work with the GUI TextWrangler<\/a> (when on a Mac) if there is going to be much cutting, copying and pasting, but you should know that vi<\/i> has functionality to do with buffers, and some years back, there were maybe 6 or 7 days I’d have preferred to do copying and pasting between buffers using vi<\/i> … you’re right … I’ll “take a Bex”<\/a> and lie down now.<\/p>\n

Here is a link to some downloadable C code you could call Hello.c<\/a> and its associated makefile<\/a> designed for Linux command line compilation via gcc<\/i><\/a> (and here is a good tutorial regarding makefiles<\/a> for gcc<\/i> compiler … thanks).<\/p>\n
