+## Don't add spaces after the slash in './file'
+
+### Problematic code:
+
+```sh
+gcc -o myfile file.c
+./ myfile
+```
+
+### Correct code:
+
+```sh
+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`.
