GitHub entry and daily operation commands (with two errors and solutions)

What ' s git & git hub.

Development environment: Linux,git Tools

1. Register an account first.

2. Generate SSH Again (website very detailed, step-by-step)

3. Create a repository (used to put the Project warehouse) again.

Create and write the relevant name on GitHub first, and then create a folder in which to contact it locally.

$CD ~
$mkdir github_jff-rtos    //local directory name and repository name is not necessarily the same, related can be
$cd ~/github_jff-rtos      //Enter Github_ Jff-rtos Directory

Copy the code you want to host here:

If you select the 3rd step of 4, you need to perform the first

$git Pull Origin Master

From Github.com:mintist/jff-rtos

Note: That's the two files that GitHub automatically helps you generate, pull it down first ~ ~ ~

otherwise ~ ~ ~ also nothing, go back first ~ ~ ~

$git init                             //initialization

$git Add.                            Add all the files to the index (do not want to add all the files, you can use Gitignore or add specific files, see below)
$git commit-m "OK, this is not       a rtos~~~"//Submit to the local warehouse, and then fill in the update log

$git Remote Add Origin git@github.com:mintist/jff-rtos.git        //Add to Remote

$git Push Origin Master    //push (push) to GitHub

Merge the remote changes (E  . G. ' Git pull ') before pushing again. See the
' Note about Fast-forwards ' sections of ' git push--help ' for details.

If you encounter an error, then PullJust a little bit better ~ ~

and some of the usual updates what to see below, pro-Test available ~ ~ ~

Summarize the commands commonly used in Ubuntu under GitHub, set part skipping, assuming repository's name is Hello-world:

1. Create a new repository:

Create and write the relevant name and description on GitHub first.

$CD ~/hello-world//To Hello-world directory, the local directory name is not necessarily the same as the repository name

$git Init//initialization

$git Add. Add all the files to the index (do not want to add all the files, you can use Gitignore or add specific files, see below)

$git Commit//Submit to the local warehouse, and then fill in the Update log (-M "Update log" can also, such as $git commit-m "My first vesion of ...")

$git Remote Add Origin git@github.com:wadeleng/hello-world.git//Add to Remote

$git Push Origin master//push to GitHub

2. Update the project (new file added):

$CD ~/hello-world

$git Add. This will automatically determine which files are added, or manually add the file name

$git Commit//Submit to the local warehouse, no parameters will prompt, note: ^=ctrl, follow the prompts to be good ~ ~ ~

$git Push Origin master//not newly created, no more add to remote

3. Update the project (no new files, only delete or modify the file):

$CD ~/hello-world

$git commit-a//record which files were deleted or modified

$git Push Origin master//submit to GitHub

4. Ignore some files, such as *.O, etc.:

$CD ~/hello-world

$vim. Gitignore//Add the file type to the. Gitignore, save

Then you can git Add. can automatically filter this file

5.clone code to Local:

$git Clone Git@github.com:wadeleng/hello-world.git

If the code exists locally, and the repository has updates, merge the changes into the local project:

$git fetch origin//Get remote Updates

$git Merge Origin/master//merge updated content into local branch

6. Revocation

$git Reset

7. Delete

$git RM *//Not in RM

------------------------------Common Errors-----------------------------------

1.$ git remote add Origin git@github.com:wadeleng/hello-world.git

Error Tip: Fatal:remote origin already exists.

WORKAROUND: $ git Remote RM origin

Then execute: $ git Remote add Origin git@github.com:wadeleng/hello-world.git will not report an error

2. $ Git push origin master

error Hint: error:failed to push som refs to

Workaround: Git pull Origin master//put the file above github on the remote server first, then push it up.
