Git Notes

Git notes:
­git­config -­global core. Editor notepad++
Git init
Create .gitignore file with following contents:
Git add .
Git commit –m “your comment”

$ git config –list

If you modify a file after you run git add, you have to run
git add again to stage the latest version of the file:

The rules for the patterns you can put in the . gitignore file are as follows:
• Blank lines or lines starting with # are ignored.
• Standard glob patterns work.
• You can end patterns with a forward slash (/) to specify a directory.
• You can negate a pattern by starting it with an exclamation point (! ).
Glob patterns are like simplified regular expressions that shells use. An asterisk (*) matches
zero or more characters; [ abc] matches any character inside the brackets (in this case a, b, or c);
a question mark (?) matches a single character; and brackets enclosing characters separated by
a hyphen ([0- 9]) matches any character between them (in this case, 0 through 9).

Here is another example .gitignore file:
# a comment – this is ignored
*. a # no . a files
! lib. a # but do track lib. a, even though you’ re ignoring . a files above
/TODO # only ignore the root TODO file, not subdir/TODO
build/ # ignore all files in the build/ directory
doc/*. txt # ignore doc/notes. txt, but not doc/server/arch. txt

If you want to see what you’ve staged that will go into your next commit, you can use git
diff –- cached. (In Git versions 1.6.1 and later, you can also use git diff –- staged, which may
be easier to remember.) This command compares your staged changes to your last commit:

It’s important to note that git diff by itself doesn’t show all changes made since your last
commit—only changes that are still unstaged. This can be confusing, because if you’ve staged
all of your changes, git diff gives you no output.
Thus git diff = difference between latest and staged
git diff –cached = difference between staged and committed

Although it can be amazingly useful for crafting commits exactly how you want them, the staging
area is sometimes a bit more complex than you need in your workflow. If you want to skip the
staging area, Git provides a simple shortcut. Providing the -a option to the git commit command
makes Git automatically stage every file that is already tracked before doing the commit, letting
you skip the git add part:

$ git rm *~
This command removes all files that end with ~.

$ git mv file_from file_to
However, this is equivalent to running something like this:
$ git rm README. txt
$ git add README

$ git log –pretty=format:”%h – %an, %ar : %s”
ca82a6d – Scott Chacon, 11 months ago : changed the version number
085bb3b – Scott Chacon, 11 months ago : removed unnecessary test code
a11bef0 – Scott Chacon, 11 months ago : first commit

$ git log –since=2.weeks

For example, if you want to see which commits in the Git source code history were committed by Junio Hamano and were not merges in the month of October 2008, you can run
something like this:
$ git log — pretty=” %h: %s” – – author=gitster — since=”2008- 10- 01″
– -before=”2008- 11- 01″ – -no- merges – – t/

As an example, if you commit and then realize you forgot to stage the changes in a file you
wanted to add to this commit, you can do something like this:
$ git commit – m ‘ initial commit’
$ git add forgotten_file
$ git commit – – amend
All three of these commands end up with a single commit—the second command
replaces the results of the first.

to undo your pending changes:
git checkout — FILE

to make backup on f: drive:
1. cd to f: from cmd.exe
2. run “c:Program Filesgitbinsh.exe” –login -i
3. mkdir my_repository
4. cd my_repository
5. git init –bare
6. now cd to the directory in c:
7. git push –mirror “f:my_repository” (execute this command periodically to make backups)

To f:git
* [new branch] master -> master

Uploading local repository to BitBucket
1. Create empty repository on bitbucket
2. git remote add bb https://URL. this adds a remote repository named bb
3. git push bb master. this pushes the master (which is the local repo) to bb
You are set.
then to push updates just do:
git push bb master

To push to non-master branch use:

git push <remote> <local-branch>:<remote-branch>

e.g., git push bb master:pro
