Question

Some of Facebooks programmer puzzles look fun, so I’m trying to get set up to code in C++ on my mac. I decided to try compiling some of my old CS homework with GCC to get started.

My code compiles fine, but when I try to run the executable (called “encrypt”) I get this:

-bash: encrypt: command not found

I checked the permissions on the file and it seems to have execute permission. What am I missing here?

Answer 1

The current directory isn’t in your $PATH, so you have to tell the shell to execute encrypt in the current directory.

./encrypt

or

/path/to/directory/encrypt
