The given command is using the pipe character "|", which is used to forward the output of one command as input to another command.
In this case, the output of the command represented by "${command}" is being sent as input to the "clamdscan -" command.
The "${command}" represents a placeholder or variable that should be replaced with an actual command by the user. Whatever output is generated by this command will be piped (or passed) to the "clamdscan -" command.
The "clamdscan" command is a command-line tool for scanning files and directories for malware or viruses using the ClamAV antivirus engine. The "-" symbol at the end of the command is used to specify that the inputs to be scanned are received via standard input (stdin) rather than as filenames or directories.
