Useful Commands

add everything to the commit (including new file and files that were deleted):

git add -A

commit all of the changes:

git commit -m "some message about what you did"

push to remote account:

git push origin master

view current tags:

git tag

making a new tag:

git tag -a V0.0.1 -m " new version 0.0.1"

committing a tag:

git push origin master --tags

checkout a tag:

git checkout -b [branchname] [tagname]

see which branch you are on:

git branch

connecting to github:

git remote add origin git@github.com:username/new_repo

• making a branch look here

Then make a new repository using the interweb

• Check out this link for more info.

Caching your github password:

git config --global credential.helper 'cache --timeout=3600'
# Set the cache to timeout after 1 hour (setting is in seconds)

Another way to connect to github it using ssh

Initially the error was:

febbo@febbo-HP-ZBook-17-G2:~/.julia/v0.5/VehicleModels$ git push origin master
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

• This was obtained when initially setting up the git repositories in julia after cloning a package and trying to push modifications back up to the remote repository.

• Information on this can be founds at , or by following the two steps a fix may be obtained:

  1. Make an ssh key and add it to github, following.
  2. Check out this, or use the following commands:

  • A program to hold private keys for public authentication.

    type:

    ssh-agent
    

  • Initially the agent does not hold any private keys.

    So run:

    ssh-add
    

Mistakes I Made

• Make sure that you are working on the master branch!

  • Do not check out a tag and start making changes only to realize that you are not on the master branch!

• Trying to connect to github using ssh

  1. Create a github repository, with the name ( for example: huckl3b3rry87/LiDAR.jl )
  2. Then

  Type this in the terminal:

  febbo@febbo-HP-ZBook-17-G2:~/.julia/v0.5/LiDAR$ git remote add origin git@github.com:huckl3b3rry87/LiDAR.jl
  

  3. Then

  Try this:

  febbo@febbo-HP-ZBook-17-G2:~/.julia/v0.5/LiDAR$ git pull master
  

  4. Next

  Get this:

  fatal: 'master' does not appear to be a git repository
  fatal: Could not read from remote repository.
  
  Please make sure you have the correct access rights
  and the repository exists.
  

  Next we are going to test the ssh connection

  5) Attempt to ssh to GitHub By typing:

  febbo@febbo-HP-ZBook-17-G2:~/.julia/v0.5/LiDAR$ ssh -T git@github.com
  Hi huckl3b3rry87! You've successfully authenticated, but GitHub does not provide shell access.
  

  6) realize that you messed up by typing:

  git pull master
  

  and not:

  git pull origin master
