The best way to use git is from the command line. There are also a bunch of gui git clients available. These gui clients are essentially a wrapper around the git command line. However none of the gui clients fully utilise the git command line. Hence it is best to invest the time in learning how to use the git command line so that you have full control over git.
On windows, you can use git from the powershell terminal. However the git installation also comes with it's own git terminal called "git-bash" which enhance your experience in using git (e.g. syntax highlighting).
Here's git's main help info:
[vagrant@localhost ~]$ git help usage: git [--version] [--exec-path[=GIT_EXEC_PATH]] [--html-path] [-p|--paginate|--no-pager] [--no-replace-objects] [--bare] [--git-dir=GIT_DIR] [--work-tree=GIT_WORK_TREE] [--help] COMMAND [ARGS] The most commonly used git commands are: add Add file contents to the index bisect Find by binary search the change that introduced a bug branch List, create, or delete branches checkout Checkout a branch or paths to the working tree clone Clone a repository into a new directory commit Record changes to the repository diff Show changes between commits, commit and working tree, etc fetch Download objects and refs from another repository grep Print lines matching a pattern init Create an empty git repository or reinitialize an existing one log Show commit logs merge Join two or more development histories together mv Move or rename a file, a directory, or a symlink pull Fetch from and merge with another repository or a local branch push Update remote refs along with associated objects rebase Forward-port local commits to the updated upstream head reset Reset current HEAD to the specified state rm Remove files from the working tree and from the index show Show various types of objects status Show the working tree status tag Create, list, delete or verify a tag object signed with GPG See 'git help COMMAND' for more information on a specific command. [vagrant@localhost ~]$
However this doesn't list all the commands, just the most commonly used git commands. If you do "git help help", then you'll discover there is an "--all" option, which if you try, you'll discover a lot more git commands:
[vagrant@localhost ~]$ git help --all usage: git [--version] [--exec-path[=GIT_EXEC_PATH]] [--html-path] [-p|--paginate|--no-pager] [--no-replace-objects] [--bare] [--git-dir=GIT_DIR] [--work-tree=GIT_WORK_TREE] [--help] COMMAND [ARGS] available git commands in '/usr/libexec/git-core' ------------------------------------------------- add filter-branch merge-subtree rev-list add--interactive fmt-merge-msg merge-tree rev-parse am for-each-ref mergetool revert annotate format-patch mktag rm apply fsck mktree send-pack archive fsck-objects mv shell bisect gc name-rev shortlog bisect--helper get-tar-commit-id notes show blame grep pack-objects show-branch branch hash-object pack-redundant show-index bundle help pack-refs show-ref cat-file http-backend patch-id stage check-attr http-fetch peek-remote stash check-ref-format http-push prune status checkout imap-send prune-packed stripspace checkout-index index-pack pull submodule cherry init push symbolic-ref cherry-pick init-db quiltimport tag clean instaweb read-tree tar-tree clone log rebase unpack-file commit lost-found rebase--interactive unpack-objects commit-tree ls-files receive-pack update-index config ls-remote reflog update-ref count-objects ls-tree relink update-server-info describe mailinfo remote upload-archive diff mailsplit remote-ftp upload-pack diff-files merge remote-ftps var diff-index merge-base remote-http verify-pack diff-tree merge-file remote-https verify-tag difftool merge-index repack web--browse difftool--helper merge-octopus replace whatchanged fast-export merge-one-file repo-config write-tree fast-import merge-ours request-pull fetch merge-recursive rerere fetch-pack merge-resolve reset See 'git help COMMAND' for more information on a specific command.
