来自其他答案，这对我有用：

echo
osType=$(uname)

"Darwin")
{
echo "Running on Mac OSX."
CURRENT_OS="OSX"
} ;;
"Linux")
{
# If available, use LSB to identify distribution
if [ -f /etc/lsb-release -o -d /etc/lsb-release.d ]; then
DISTRO=$(gawk -F= '/^NAME/{print }' /etc/os-release)
else
DISTRO=$(ls -d /etc/[A-Za-z]*[_-][rv]e[lr]* | grep -v "lsb" | cut -d'/' -f3 | cut -d'-' -f1 | cut -d'_' -f1)
fi
CURRENT_OS=$(echo $DISTRO | tr 'a-z' 'A-Z')
} ;;
*)
{
echo "Unsupported OS, exiting"
exit
} ;;
esac
}
