snoop:tldr:8358c
The given command is the usage of the "snoop" command with some options and an input file specified by the "${filename}" variable.
Here is a breakdown of each component of the command:
-
"snoop": It is a command-line packet analyzer tool primarily used on Unix-like operating systems, such as Linux or macOS. It captures the network traffic on a specific network interface, allowing you to analyze the packets and monitor the network activity.
-
"-V" (or "--version"): It is an option used to display the version of the "snoop" command, which provides information about the version number and other details of the tool.
-
"-i {filename}": This option specifies the input file or network interface to sniff packets from. In the given command, "${filename}" is used as a placeholder for the actual file or interface name that you need to provide. For example, if you wanted to capture packets from a network interface named "eth0", you would replace "${filename}" with "eth0" in the command.
So, when you run the command with a specific filename or network interface, "snoop" will start capturing packets on that interface or from the specified file, allowing you to analyze the network traffic. Additionally, the "-V" option is used to display the version information of the "snoop" command.
