Git

Git is a free and open distributed version control system for handling small to very large projects with speed and efficiency.

Installation from repository

Git can be installed using the terminal, enter:

apt-get

su -
apt-get update
apt-get install git

epm

epm -i git

Settings

To work with git version control, you need to configure your working environment:

View current settings

To view your current settings, you can view all configurations or just global ones using the following commands:

To view all configurations by type (local, global):

git config --list --show-origin

To view global configurations:

git config --global --list

Adding additional settings

To add additional settings, use the config command, with a configuration key and its value. You can add the --global option for one project (local) or for all (global). We use the following commands using the status.short setting as an example:

Run the command to add local configuration:

git config status.short true

Run the command to add global configuration:

git config --global status.short true

Removing advanced settings

To remove additional settings, use the config --unset command with the configuration key. For example, to remove a username:

git config --global --unset user.name

Resetting Git configurations to default values

If you need to reset all global configurations to default values, delete the global configuration file:

rm ~/.gitconfig

The command will delete the global Git configuration file, which will reset all global settings to their default values the next time they are used.

Settings after installing git

Personal information

Enter your name and email address. This information will be included in every commit and will remain unchanged. To do this you need to enter into the terminal:

git config --global user.name "username"
git config --global user.email "email@example.com"

Информация

Don't forget to replace username and email@example.com with your username and email in quotes.

Note that the --global option will cause this setting to be applied to all your commits by default.

If you want to apply settings only to a specific repository, you need to log into that repository and run the commands without the --global option.

Default master branch name

Optionally, you can customize the name of the main branch. The default name is master, but GitHub usually uses the name main. To change the name of the master branch to main, run the following command in the terminal:

git config --global init.defaultBranch main

Информация

If you need to set an option only for a specific repository, you need to go to that repository and run the command without the --global option:

Problems and possible solutions when using git

When submitting a commit, the following error occurs:

> git push origin main:main
error: RPC failed; HTTP 400 curl 22 The requested URL returned error: 400
send-pack: unexpected disconnect while reading sideband packet
fatal: the remote end hung up unexpectedly
Everything up-to-date

A possible fix is to increase the size of postBuffer to 500 MB, for example. Make settings in the working environment using the terminal:

git config --global http.postBuffer 500M
