./a.out
Alternatively, if you don't want it to compile to a.out you can use the -o option. Like gcc mytest.c -o test will create an executable named test (which you run of course with ./test)
Although "test" is a very bad name for a program in unix, as there is a standard command that is called test - often a builtin of the command shell.Originally Posted by C_ntua

Compilers can produce warnings - make the compiler programmers happy: Use them!
Please don't PM me for help - and no, I don't do help over instant messengers.
haha I remember wasting loads of time when I tried running a program named test on linux for the first time. But it's one of those things you have to go through to learn that you always use ./ when running executables in the current directory
Thanks. Why is it ./a.out instead of just a.out?
Just writing "program" will try to find the program in all of the directories specified in your path environment variable, which does not contain your current working directory in most cases. This is why you need to use "./" - . means the current directory.
"What's up, Doc?"
"'Up' is a relative concept. It has no intrinsic value."
LOL! I thought ./ meant something like "run". Like run a.out. All this time, I was misguided. I see the light now...
I see, that makes sense. Thanks.
It's like that so you can run regular commands without programs in the present working directory masking them.
