GIT Pull using Ubuntu 16.04.2 LTS - linux

I want to be able to pull down my source code from GitHub automatically, but currently doing it manual using the process below.
Currently i have to do this by going
$ sudo -i
Then I CD to my directory, once in I run the following command
$ git pull origin master
the command then asks for me to enter my key password
Enter passphrase for key '/root/.ssh/id_rsa':
This then pulls the latest code down from GitHub.

A beginning note: does your repo really need to be pulled as root? Why? It's probably not a good idea to be doing that.
Github supplies https pull links that anyone can use to pull without needing a key. So, we can add another remote, used specifically for this purpose, that pulls using the https link.
git remote add autopull https://github.com/<user>/<repo>.git
Now you can change your pull command to:
git pull autopull master
From there, you can put it in .profile, .bash_profile, .bashrc, or maybe even a cron script. You haven't specified how you want to automate it, though, so I can't give any specific examples.
It should be noted that this can only work for public repositories. If this is a private repository, you should create another keypair that has no passphrase required. If it isn't your default keypair you can make use of a trick.
ssh-agent bash -c 'ssh-add /path/to/yourkey; git pull autopull master'
Or another answer to the same question:
GIT_SSH_COMMAND='ssh -i /path/to/yourkey' git pull autopull master

Add a comment to SVN file

I'm exporting a file in one folder and moving it to production without performing an change, using this command:
svn export --username user --password passwd --non-interactive --force svn://svnserver.com/trunk/patch/115/sql/TestFile.sql
After the movement I would like to add a comment/tag that file was moved successfully. For this, I tried the commands below but they didn't work:
> svn commit -m " Test" TestFile.sql
svn: '/home//SVNTEST/1' is not a working copy
> svn commit -m "Test" svn://svnserver.com/trunk/patch/115/sql/TestFile.sql
svn: Must give local path (not URL) as the target of a commit
Will it be possible if yes how to do so?
To summarize, you're copying a file from the repository to your local machine, then you want to somehow indicate in the repository that this action happened.
Without knowing more about your setup, I think creating a tag is probably the most straightforward way to do this. Use this command:
svn copy svn://svnserver.com/trunk/ svn://svnserver.com/tags/115 -m "Test"
Use whatever unique key for the tag name (here I used '115' since it seemed like that was a patch identifier).
Let's discuss why the commands you tried did not work.
Since you're exporting rather than checking out the file, you don't have a working copy. Exporting is basically equivalent to downloading a file from an HTTP or FTP server; there are no strings attached.
Now, the subcommand commit requires a working copy (in order to know where in the repository to put your local changes), which explains why in the first command you tried the error indicated you aren't in a working copy. The second command errored because you (I think) are trying to tell SVN the remote location to upload your local TestFile.sql, which is not a valid use-case for the commit subcommand.
My suggestion creates a tag, but does so entirely on the server which means you don't need a working copy.

Issue with GIT command

I am trying to execute git clone command to clone source code from github repository. I am using 2.11.1 version. command I run is
git clone https://username:password#github.com/repository.git ./localpath
This works fine at windows machine. But when I am executing from linux machine command is removing # and throwing error. Execution failure is like
git clone https://username:passwordgithub.com/repository.git ./localpath Cloning into './localpath'...
error: Couldn't resolve host username:passwordgithub.com while accessing
Could someone help me to fix this?
Register your ssh-keygen generated id to Github so it would not prompt you for password.
$ ssh-keygen
No need to enter pass-phrase. Output your public key, then copy it to github
$ cat ~/.ssh/id-rsa.pub
But, if you really want to go that route.
Enclose them in a single quotation, or do them like below.
#!/bin/bash
REPO='https://username:password#github.com/repository.git'
LOCAL_PATH='path/to/wherever'
git clone "$REPO" "$LOCAL_PATH"
Note: Use double quotations for variables

Howto pull latest revision of a git repository on system startup

I'm trying to update a git repository on system startup.
I called a Script from /etc/rc.local which is executed.
In that script I do the following steps:
1) Enter the folder where repo was cloned to
2) Do a git pull in that folder in two different ways
1st way simple git pull > /home/user/result.txt (doesn't work)
2nd way git --git-dir=/home/pi/gitrepo/.git pull origin master > /home/user/result.txt
What do I need to do to get this working?
Also tried to test if internet connection is already available with a simple wget which was successful
Thanks in advance
I expect this to be a problem with public key authentication.Note that commands during startup are executed as root, but you've likely registered a regular user's key at github.
Solution: register a machine key at github and use that key for the pull, like described here

Git - Syncing a Github repo with a local one?

First off, forgive me if this is a duplicate question. I don't know anything but the basic terminology, and it's difficult to find an answer just using laymen's terms.
I made a project, and I made a repository on Github. I've been able to work with that and upload stuff to it for some time, on Windows. The Github Windows application is nice, but I wish there was a GUI for the Linux git.
I want to be able to download the source for this project, and be able to edit it on my Linux machine, and be able to do git commit -m 'durrhurr' and have it upload it to the master repository.
Forgive me if you've already done most of this:
The first step is to set up your ssh keys if you are trying to go through ssh, if you are going through https you can skip this step. Detailed instructions are provided at https://help.github.com/articles/generating-ssh-keys
The next step is to make a local clone of the repository. Using the command line it will be git clone <url> The url you should be able to find on your github page.
After that you should be able to commit and push over the command line using git commit -am "commit message" and git push
You can use SmartGit for a GUI for git on Linux: http://www.syntevo.com/smartgit/index.html
But learning git first on the command line is generally a good idea:
Below are some basic examples assuming you are only working from the master branch:
Example for starting a local repo based on what you have from github:
git clone https://github.com/sampson-chen/sack.git
To see the status of the repo, do:
git status
Example for syncing your local repo to more recent changes on github:
git pull
Example for adding new or modified files to a "stage" for commit
git add /path/file1 /path/file2
Think of the stage as the files that you explicitly tell git to keep track of for revision control. git will see the all the files in the repo (and changes to tracked files), but it will only do work on the files that you add to a stage to be committed.
Example for committing the files in your "stage"
git commit
Example for pushing your local repo (whatever you have committed to your local repo) to github
git push
What you need to do is clone your git repository. From terminal cd to the directory you want the project in and do
git clone https://github.com/[username]/[repository].git
Remember not to use sudo as you will mess up the remote permissions.
You then need to commit any changes locally, i.e your git commit -m and then you can do.
git push
This will update the remote repository.
Lastly if you need to update your local project cd to the required directory and then:
git pull
To start working on the project in linux, clone the repo to linux machine. Add the ssh public key to github. Add your username and email to git-config.
For GUI you can use gitg.
PS : Get used to git cli, It is worth to spend time on it.

gitolite hook for specific repository

I don't understand how do I create a post-receive hook for a specific repository in gitolite (non-root install)
My bare repository contains a website that should copy the working directory to the docRoot
(GIT_WORK_TREE=/path/htdocs git checkout -f) on update
Before gitolite, I would just update the hook for the specific repository.
Gitolite documentation mentions that all hooks should be at hooks/common so I don't understand how it works.
What should be the name of hooks, where it should be located and how it's structure should be changed (if it should)?
Update July 2013: what follows is for gitolite V2 (or 'g2'), which was the version used by the OP at the time (November 2011).
Update August 2013, with the latest gitolite 3.x:
You now have official specific repo hook:
it's basically just creating a symlink in <repo.git>/hooks pointing to some file inside $rc{LOCAL_CODE}/hooks/repo-specific (except the gitolite-admin repo)
All hooks in gitolite/hooks/common are replicated in all repositories managed by Gitolite, as detailed in the hook propagation documentation.
That means your hook script must take specific action depending on the repo which execute said hook.
You can either use the $GL_REPO variable (which gitolite set and pass to all its scripts for any git command it receives).
Or you can use some git configuration registered on the gitolite server, like the mirroring hook does. See the post-receive.mirrorpush hook.
The OP Eyal R adds in the comments:
But I still don't understand how it is done (I understand that $GL_REPO is used to determine which repo I am updating but I'm missing the practical part).
I have created a file called post-receive.test with echo "test", put it in $HOME/gitolite/hooks/common, ran gl-setup, ran push from workstation - nothing happens (no "test" output)
To which I replied:
The hook should appear in the hook directory of your repo on the gitolite server as a link, linking back to the .gitolite/common/hook. Note that it should be in $HOME/.gitolite/common/hook, not /gitolite.
The OP confirms the missing dot was the issue.
The process to add an hook is detailed in Hook propagation in gitolite, and their usage in "Using Hooks".
This is a fairly common need for someone using gitolite, and appears to be a little difficult to tie up loose ends when being not a very advanced user (at leas it was for me).
Following stackoverflow's and gitolite's links back and forth can be a little confusing. These are my conclusions and the path I followed to be able to achieve this.
As #VonC mentioned creating repository specific hooks is already possible since version 3.5.3.1 (github link)
Update/Upgrade Gitolite
The first thing you should do is update your gitolite repo. So ssh into your server that is hosting gitolite and move to the location where gitolite is installed (usually /home/git/gitolite) as the git user (usually git)
Example:
$ ssh myusername#devserver.com
$ sudo su - git
$ pwd
/home/git
$ cd gitolite
Then we have to upgrade gitolite. To do so, first we need to update the gitolite repository
$ git pull
Then we have to repeat the install command (make sure you use the same arguments as before)
$ ./install
And finally run the setup again.
$ gitolite setup
If that doesn't work, you probably haven't set up gitolite executable in your PATH, so you could do something like this:
$ src/gitolite setup
Gitolite Settings (The "RC" file)
This was one of the parts that confused me the most, but it ended up it was pretty straight forward.
The famous "rc" file is located at git's home directory /home/git/.gitolite.rc. There make sure you have a variable called LOCAL_CODE, you should see something like this on that file, if not, add it.
LOCAL_CODE => "$ENV{HOME}/.gitolite/local"
And in the "commands an feature to enable" section you should make sure that repo-specific-hooks is available, if not, add it.
ENABLE => [
# COMMANDS
# These are the commands enabled by default
'help',
'desc',
'info',
...,
...,
...,
'repo-specific-hooks'
...,
...,
...
]
Here is the link to the documentation
Writing Repository Specific Hooks
Finally, in your local gitolite-admin repository create the following directories hooks/repo-specific under the directory you just set in the LOCAL_CODE variable, for example:
gitolite_admin/local/hooks/repo-specific
After that you can actually add your hooks scripts to that location and manage them through the gitolite conf file as stated in the documentation. Make sure the scripts are executable.
repo foo
RW+ = #all
option hook.post-receive = deploy
Again, I hope this helps some of you guys.
Cheers!
