Ruby on rails Rake Capistrano-如何传递动态参数以执行shell命令

在我的Rake capistrano脚本中，我正在创建需要动态参数的shell命令。我的rake代码如下

execute "sed -i '/SPARK_HOME=/c\\export SPARK_HOME=<arg1>' #{release_path}/backend_layer/configs/hdfs/cluster.sh"

执行“sed-i'/SPARK_HOME=/c\\export SPARK_HOME='{release_path}/backend_layer/configs/hdfs/cluster.sh”

我如何调用这个rake并发送参数，以便我的命令是动态的

desc 'Passing argument on rake task'
task :symlink_shared, [:arg1] => :environment do |t, args|
  execute "sed -i '/SPARK_HOME=/c\\export SPARK_HOME=#{args.arg1}' #{release_path}/backend_layer/configs/hdfs/cluster.sh"
end

cap staging postdeploy:symlink_shared[<your_arg1>]

然后，使用如下参数运行cap脚本

desc 'Passing argument on rake task'
task :symlink_shared, [:arg1] => :environment do |t, args|
  execute "sed -i '/SPARK_HOME=/c\\export SPARK_HOME=#{args.arg1}' #{release_path}/backend_layer/configs/hdfs/cluster.sh"
end

cap staging postdeploy:symlink_shared[<your_arg1>]

cap staging postdeploy:symlink_shared[]
