I’m compiling c++ programs from the OS X Terminal:
> g++ a.cpp
I then the run the program from the terminal:
> ./a.out
What does the ./ syntax mean? Is this somehow related to ./run?
.means “the current directory”, so./a.outmeans “the file nameda.outin the current directory”. If you were to type simplya.out, without the./, then the system would look through the directories on the path ($PATH) to find the program, instead of looking in the current directory.
