      ],
      "log": {
        "width": 500
      }
    }
  }

task.file.gzip: boolean

task.params: parameter and value

name1=value1 ($name1: value1)

name2=$name1 ($name2: value1)

name3=$name2 ($name3: value1)

name4=$$name1 ($name4: 790name1, the PID of this script)

name4=${BASHPID}name1 ($name4: 790name1, the PID of current instance)

name5=#name1 ($name5: #name1, invalid symbol in Bash)

task.commands: command and argument

task.log: task log

task.log.width: line width in runes (default: 500)
