The command "clamdscan --fdpass" is used to scan files or directories for malware using the ClamAV antivirus engine. Here is an explanation of each part of the command:
- "clamdscan" is the command that invokes the ClamAV scanner. ClamAV is an open-source antivirus software designed to detect malicious software such as viruses, trojans, and other malware.
- "--fdpass" is an option that allows the scanner to pass file descriptors of the files being scanned to the ClamAV daemon, which is clamd. By passing file descriptors, the command allows the scanning process to be more efficient and minimize the need to read files multiple times, resulting in faster scanning.
In summary, "clamdscan --fdpass" is a command used to scan files or directories for malware using ClamAV, with improved efficiency achieved by passing file descriptors to the ClamAV daemon.
