SFTP replaces FTP in macOS High Sierra

1. Typing: "ftp www.myDomainName.ext" in Mac's terminal now produces:
   • "-bash: ftp: command not found"
2. Typing: "sftp www.myDomainName.ext" in Mac's terminal now produces:
   • "computerusersaccountname@www.myDomainName.ext's password:"
     • Where the part to the left of the @ sign is the computer user's account name.
     • If the ftp login user's name is the same as the computer user's account name, this is fine.
       Type in the ftp password and you are good to go.
     • Otherwise, if the two user names do not match you will get a:
       "Permission denied, please try again." message.
     • If the two user names do not match, use technique #3
3. Typing: "sftp ftpUserName@www.myDomainName.ext" in Mac's terminal will produce:
   • "ftpUserName@www.myDomainName.ext's password:"
   • Entering the correct password for the ftp account should connect you as long as you also have the correct ftp user's name entered without any typos.
