I want to commit my files and type this command
git commit -a -m "all base files"
There is nothing wrong here. The untracked files simple means git found some file in your local(your PC) which is not present in the remote (git repo), that means you have created new files. To commit this you can do these commands:
$git status //optional, this will show all the files which are changed and which have added to next commit and which are not.
$git add . //this will add all the file which are changed to next commit.
$git add "filepath" //this will add only specific file to next commit.
$git commit -m "all base files"
