NAME

SYNOPSIS

links2 [options] URL

DESCRIPTION

links2 is a text mode WWW browser with ncurses interface, supporting colors, correct table rendering, background downloading, menu driven configuration interface and slim code.

Frames are supported. You can have different file formats associated with external viewers. mailto: and telnet: are supported via external clients.

links2 can handle local (file://) or remote (http:// or ftp://) URLs.

OPTIONS

Most options can be set in the user interface or config file, so usually you do not need to care about them.

-help

Print a help screen

-version

Prints the links version number and exit.

-lookup <hostname>

Does name lookup, like command "host".

-g

Run Links2 in graphics mode. If not given, Links2 will run in text mode. Running in graphics mode means that Links2 will probe all compiled‐in graphics devices and run on the first found.

Run in text mode (overrides previous -g).

PLATFORMS

links2 is known to work on Linux, FreeBSD, Solaris, IRIX, HPUX, Digital Unix, AIX, OS/2, BeOS and Win32.

BUGS

Can't connect to some FTP servers (Novell, NT). Connection stays in "Request sent" state.

Frames don't work if there's more frames with same name. Turn them off in such case.

You can't upload large files; it takes _lots_ of memory.

You shouldn't press '^Z' when you are in a viewer
