A mesma pergunta é feita em U & L SE que Qual é a diferença entre curl e wget? . E as diferenças são:
- Wget's major strong side compared to curl is its ability to download recursively.
- Wget is command line only. There's no lib or anything but curl Features and is powered by libcurl.
- curl supports FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP, TELNET, DICT, LDAP, LDAPS, FILE, POP3, IMAP, SMTP, RTMP and RTSP. Wget supports HTTP, HTTPS and FTP.
- curl builds and runs on lots of more platforms than wget.
- Wget is part of the GNU project and all copyrights are assigned to FSF. The curl project is entirely stand-alone and independent with no organization parenting at all
- curl offers upload and sending capabilities. Wget only offers plain HTTP POST support.

If telnet is invoked without the host argument, it enters command mode, indicated by its prompt (telnet> ) In this mode, it accepts and executes the commands listed below. If it is invoked with arguments, it performs an open command with those arguments.
