02- Basic Configuration

- Create system "/etc/gitconfig" configuration file which is the system wide configuration file:

1. Create new "system name" to be added on whole system:

[root@git-server ~]# git help config
       --system
           For writing options: write to system-wide $(prefix)/etc/gitconfig rather than the repository .git/config.

[root@git-server ~]# git config --system system.name "Git Repo Server 1"

[root@git-server ~]# cat /etc/gitconfig 
[system]
 name = Git Repo Server 1

Note: /etc/gitconfig was not created, it is created after applying above Git command.

2. Now, list the current Git attributes:

[root@git-server ~]# git config --list
system.name=Git Repo Server 1
user.name=Root User
user.email=root@localhost

- Overwrite "system.name" in /etc/gitconfig":

[root@git-server ~]# git config --global system.name " My Git Repo Server1"

[root@git-server ~]# git config --list
system.name=Git Repo Server 1
user.name=Root User
user.email=root@localhost
system.name= My Git Repo Server1   <------

root@git-server ~]# pwd
/root
[root@git-server ~]# cat .gitconfig 
[user]
 name = Root User
 email = root@localhost
[system]
 name = " My Git Repo Server1"

Set "vim" editor as the default editor we will use:

[root@git-server ~]# git config --global core.editor vim

[root@git-server ~]# pwd
/root

[root@git-server ~]# cat .gitconfig 
[user]
 name = Root User
 email = root@localhost
[system]
 name = " My Git Repo Server1"
[core]
 editor = vim

[root@git-server ~]# git config --list
system.name=Git Repo Server 1
user.name=Root User
user.email=root@localhost
system.name= My Git Repo Server1
core.editor=vim

- Let 'more' command being the Git Pager:

[root@git-server ~]# git config --global core.pager 'more'

[root@git-server ~]# pwd
/root

[root@git-server ~]# cat .gitconfig 
[user]
 name = Root User
 email = root@localhost
[system]
 name = " My Git Repo Server1"
[core]
 editor = vim
 pager = more

[root@git-server ~]# git config --list
system.name=Git Repo Server 1
user.name=Root User
user.email=root@localhost
system.name= My Git Repo Server1
core.editor=vim
core.pager=more

- From time to time, there are files you don't want Git to check. so do the following:

1. Create exclude file:

[root@git-server ~]# pwd

[root@git-server ~]# vim .gitignore_global

[root@git-server ~]# cat  .gitignore_global
*~
.DS_Store

2. Configure Git to use above exclude file:

[root@git-server ~]# pwd
/root

[root@git-server ~]# vim .gitignore_global

[root@git-server ~]# cat  .gitignore_global
*~
.DS_Store

[root@git-server ~]# git config --global core.excludesfile ~/.gitignore_global

[root@git-server ~]# pwd
/root

[root@git-server ~]# cat .gitconfig 
[user]
 name = Root User
 email = root@localhost
[system]
 name = " My Git Repo Server1"
[core]
 editor = vim
 pager = more
 excludesfile = /root/.gitignore_global

[root@git-server ~]# git config --list
system.name=Git Repo Server 1
user.name=Root User
user.email=root@localhost
system.name= My Git Repo Server1
core.editor=vim
core.pager=more
core.excludesfile=/root/.gitignore_global
