The command "wondershaper -a ${adapter_name} -d ${1024}" uses the wondershaper utility to limit the download speed (in this case, to 1024 kilobits per second) of a specific network adapter.
Here's a breakdown of the command:
-
"wondershaper": This is the name and the actual command of the utility you are executing.
-
"-a ${adapter_name}": This flag specifies the network adapter to which you want to apply the bandwidth limitation. "${adapter_name}" is a placeholder that should be replaced with the actual name of the network adapter. For example, if you want to limit the bandwidth of the "eth0" adapter, you would replace "${adapter_name}" with "eth0".
-
"-d ${1024}": This flag sets the download speed limit for the chosen network adapter. "${1024}" is a placeholder that should be replaced with the desired download speed limit in kilobits per second. In this case, it is set to 1024 kilobits per second.
Overall, this command is used to control the download speed of a specific network adapter using the wondershaper utility.
