ftp is the standard File Transfer Protocol client for transferring files between local and remote systems. It provides an interactive command interface for file operations.
The client supports navigation, file listing, binary/ASCII transfer modes, and batch transfers. Passive mode helps with firewalls. The protocol transmits credentials in cleartext.
ftp remains useful for accessing legacy systems and public FTP archives.
