The default git version is 1.18, how to upgrade it to git 2?

yum install \
https://repo.ius.io/ius-release-el7.rpm \
https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

sudo yum remove git*

sudo yum -y install  git2u-all

OK, it's done. Check the version now:

$ git --version
git version 2.16.6

1. To check the branch in the local repository

# Local:
# https://stackoverflow.com/questions/21151178/shell-script-to-check-if-specified-git-branch-exists
# test if the branch is in the local repository.
# return 1 if the branch exists in the local, or 0 if not.
function is_in_local() {
    local branch=${1}
    local existed_in_local=$(git branch --list ${branch})

    if [[ -z ${existed_in_local} ]]; then
        echo 0
    else
        echo 1
    fi
}

2. To check the branch in the remote repository

# Remote:
# Ref: https://stackoverflow.com/questions/8223906/how-to-check-if-remote-branch-exists-on-a-given-remote-repository
# test if the branch is in the remote repository.
# return 1 if its remote branch exists, or 0 if not.
function is_in_remote() {
    local branch=${1}
    local existed_in_remote=$(git ls-remote --heads origin ${branch})

    if [[ -z ${existed_in_remote} ]]; then
        echo 0
    else
        echo 1
    fi
}
