在 CentOS 系统中，env 命令主要用于显示当前环境变量

if [ "$VAR1" = "$VAR2" ]; then
  echo "Variables are equal"
else
  echo "Variables are not equal"
fi

if test "$VAR1" = "$VAR2"; then
  echo "Variables are equal"
else
  echo "Variables are not equal"
fi

if [ "$VAR1" = "$VAR2" ]; then
  echo "Variables are equal"
else
  echo "Variables are not equal"
fi

echo "$VAR1 $VAR2" | awk -F= '{if ($1 == $2) print "Variables are equal"; else print "Variables are not equal"}'

在这些示例中，$VAR1 和 $VAR2 是要比较的环境变量。请根据您的需求替换它们。
