Bash: $@ for Remaining Arguments
🧑 User
In bash what $ thing gives all remaining arguments?
🤖 Assistant
In Bash, the “$@” special parameter expands to all the positional parameters passed to a script or function, starting from the first one. This includes all the arguments that have not been assigned to any other variable, so “$@” effectively gives you all the remaining arguments.
Here’s an example to illustrate this:

If you run this script with the command ./script.sh foo bar baz, it will output:
1 | The script was called with 3 arguments. |

How do I use iperf?
🤖 Assistant
iperf is a command-line tool that allows you to measure network performance by sending and receiving data over a network. Here are the basic steps to use iperf:
Install iperf on your system: You can typically install iperf using your system’s package manager. For example, on Ubuntu, you can run sudo apt-get install iperf to install iperf.Choose a server: You need to choose a server to test the network performance against. The server should have iperf installed and be accessible over the network. You will need to know the IP address or hostname of the server.Start the server: On the server, run the command iperf -s to start the iperf server. This will listen for incoming connections from iperf clients.Run the client: On the client, run the command iperf -c
Here’s an example of running iperf:
On the server:
1 | $ iperf -s |
On the client:
1 | $ iperf -c 192.168.1.100 |
In this example, iperf reports that the network throughput was 937 megabits per second (Mbps) for the duration of the test (10 seconds).
