Thread: Help Opening C Program from Mac Terminal

Compiling a C program on Mac OS X - YouTube

A little youtube video I quickly found. It uses gcc.

John-Smiths-MacBook:desktop smith_j$ "repeat" resistance is futile
-bash: repeat: command not found

Try:

Code:

"/Users/smith_j/Desktop/C Programming Class/repeat 3-27-13 6.49 PM/usr/local/bin/repeat" resistance is futile

You can't just type "repeat" because the terminal doesn't know what you mean. It doesn't know there's a program called "repeat" somewhere deep in the file system.

If you change into the directory:

Code:

cd "/Users/smith_j/Desktop/C Programming Class/repeat 3-27-13 6.49 PM/usr/local/bin"

Then you can just run it with

Code:

./repeat

The reason you can type some executable names without specfiying where they are is usually because the directory is listed in the PATH environment variable. This is a list of places for the system to look for programs. You can change and add to PATH, but I wouldn't expect you to for a single test program like this. There's no rules saying you can't, but it'd be more hassle than just typing the location of your program.

Apologies if this is all wrong -- I've never actually used a Mac
