Linux ディストリ別 初期環境構築

Debian Ubuntu

apt update && apt install -y sudo git curl
newuser="hoge"; adduser --home "/home/$newuser" $newuser && adduser $newuser sudo && su $newuser

Fedora RHEL CentOS {Scientific,Oracle,Amazon}Linux

yum install -y sudo git passwd
echo "%wheel ALL=(ALL) ALL" >> /etc/sudoers
newuser="hoge"; adduser -d "/home/$newuser" $newuser && passwd $newuser && usermod -aG wheel $newuser && su $newuser

ArchLinux OpenSUSE Gentoo

# ArchLinux
pacman -Syy && pacman -S --noconfirm git sudo
# OpenSUSE
zypper install -y git sudo
# Gentoo
emerge-webrsync && emerge sudo git curl

echo "%wheel ALL=(ALL) ALL" >> /etc/sudoers
newuser="hoge"; useradd -m -G wheel $newuser && passwd $newuser && su $newuser

FreeBSD

pkg install -y sudo curl git bash gnuls
echo "%wheel ALL=(ALL) ALL" >> /usr/local/etc/sudoers
set newuser="hoge"; echo $newuser"::::::::bash:" | adduser -f /dev/stdin -G wheel && passwd $newuser && su $newuser

以上を考慮したパッケージマネージャー選択ShellScript

execable(){ [[ -x "$(command -v $1)" ]] || [[ "$(command -v $1)" != "" ]] ; }
if   execable brew  ; then manager="brew install"
elif execable yum   ; then manager="sudo yum install -y"
elif execable apt   ; then manager="sudo apt install -y"
elif execable pacman; then manager="sudo pacman -S --noconfirm" # ArchLinux
elif execable zypper; then manager="sudo zypper install -y" # OpenSUSE
elif execable pkg   ; then manager="sudo pkg install -y" # FreeBSD
elif execable emerge; then manager="sudo emerge" # Gentoo
else echo "no package manager"; exit 1
fi
manager(){ $manager $@ ; }
