git-commands

I got tens of repos, my script should update them if any difference happened, new commits, new tag, new branch. Fetch is kind of slow for tens of repos in my case, I'd like to know if there is any quick command could meet my requirement. mockinterface You can use the git ls-remote plumbing command to obtain the state of the remotes without fetch. Here, let’s use git itself as a lightweight database, to keep track of the state of the remote. Put the following in a script; you can enable it later as a git alias shell function for convenience. Run inside your repo. REMOTE_SUM=$(git ls-remote -

What's the difference between: git add . git commit -a Should I be doing both, or is that redundant? git commit -a means almost[*] the same thing as git add -u && git commit . It's not the same as git add . as this would add untracked files that aren't being ignored, git add -u only stages changes (including deletions) to already tracked files.

I did a pull from a remote repo and got an error message: "please enter a commit message to explain why this merge is necessary, especially if it merges an updated upstream into a topic branch." I try to type a message and press Enter but nothing happens. How do I tell Git/terminal I am done typing in my message? I am using terminal on OS X.

To solve this: press "i" write your merge message press "esc" write ":wq" then press enter xiaohu Wang Actually it's not an error! It means you should enter some

I am using the following command to find out if a local git branch with branch-name exists in my repository. Is this correct? Is there a better way? Please note that I am doing this inside a script. For this reason I'd like to stay away from porcelain commands if possible. git show-ref --verify --quiet refs/heads/<branch-name> # $? == 0 means local branch with <branch-name> exists. Update Turns out there is another way . Thanks @jhuynh . git rev-parse --verify <branch-name> # $? == 0 means local branch with name <branch-name> exists. Mark Longair As far as I know, that's the best way to do it
