wget2 命令

常用示例

说明

wget2 is the next-generation version of GNU Wget, rebuilt to support modern protocols and parallel downloading. It adds native HTTP/2 support with multiplexed streams, enabling more efficient communication with servers that support the protocol. Parallel downloading fetches multiple files simultaneously over reused connections, significantly speeding up batch downloads compared to the sequential approach of the original wget. The --chunk-size option splits large single-file downloads into parallel chunks. Recursive downloading and website mirroring are supported with the same familiar -r and -m flags. wget2 also supports Metalink files for mirror-aware downloads with automatic integrity checking, compression negotiation, and modern TLS. The tool maintains command-line compatibility with wget for basic operations while improving performance through its modernized network stack.
