Igual se necesita crear un repo en remoto que reciba al local y luego:
USUARIO@USUARIO-PC MINGW32 /f/MIS PROGRAMAS/GIT/PruebaX $ git init
Initialized empty Git repository in F:/MIS PROGRAMAS/GIT/PruebaX/.git/
USUARIO@USUARIO-PC MINGW32 /f/MIS PROGRAMAS/GIT/PruebaX (master) $ git add .
warning: in the working copy of 'README.md', LF will be replaced by CRLF the next time Git touches it
USUARIO@USUARIO-PC MINGW32 /f/MIS PROGRAMAS/GIT/PruebaX (master) $ git commit -m "Primer commit"
[master (root-commit) 96fb6c8] Primer commit 2 files changed, 2 insertions(+) create mode 100644 .gitignore create mode 100644 README.md
USUARIO@USUARIO-PC MINGW32 /f/MIS PROGRAMAS/GIT/PruebaX (master) $ git branch
