Don't add spaces after the slash in ./file.
Problematic code:
gcc -o myfile file.c
./ myfile
Correct code:
gcc -o myfile file.c
./myfile
Rationale:
Contrary to popular belief, there is no command or syntax ./ that runs a file.
./myfile is simply the shortest path equivalent to myfile that specifies a directory and therefore causes a shell to run it as-is, instead of trying to find its directory using $PATH.
Therefore, to run a file in the current directory, use ./myfile and not ./ myfile.
Exceptions:
None
