ftp (or ftp site address) at the UNIX
($) prompt. When an FTP session is initiated, the prompt changes to
ftp> . Once connected to the site, you will be asked for NAME
(your account). Type anonymous . Then, when asked for password,
type your email address (in most cases).=============================================================================== Purpose | Command =====================================================|========================= Get full list of FTP host commands within FTP session| help -----------------------------------------------------|------------------------- Initiate FTP session |ftp OR ftp site address -----------------------------------------------------|------------------------- Connect to a site if you opened a session without | open site address specifying the site name | -----------------------------------------------------|------------------------- Display name of directory you are currently in | pwd -----------------------------------------------------|------------------------- Display names of files in directory | ls -al -----------------------------------------------------|------------------------- as above, but "piped" (scrolls one screen at a time) | ls -al | more -----------------------------------------------------|------------------------- Change directory: | Absolute | /cd directory name Relative | cd directory name -----------------------------------------------------|------------------------- Move up one level in a directory structure | cd .. OR cdup -----------------------------------------------------|------------------------- Display text of specific file, pausing screen by scr.| get filename|more -----------------------------------------------------|------------------------- Transfer or copy file from FTP host to CUNIX | get filename (+ see note about binary files) | -----------------------------------------------------|------------------------- Transfer multiple files from ftp host to CUNIX: | Using multiple filenames |mget filename filename... Using wildcards (*) to substitute for some char-s.| mget *.txt -----------------------------------------------------|------------------------- Check space available in your CUNIX account | quota -v -----------------------------------------------------|------------------------- Exit FTP session | quit ===============================================================================Some larger FTP files can occupy considerable space, so make sure that you have enough space available for the file(s) you are retrieving before you launch your FTP session. Use the quota -v command to check your space quota and overall usage on your CUNIX file. Then use the pwd command to find the full name of your home directory; then match that name with the correct line of the display shown with your quota -v display. The usage, quota, and limit columns are measured in kilobytes.
If what you want is bigger than the space you have available, then you can
use the scratch directory to temporarily store larger files. You must change
your directory before you begin your FTP session: type cd /scratch
at the UNIX prompt.
After you are finished, download these files to
your microcomputer using Kermit or a PC/Mac side FTP package and delete the
files in /scratch.
There are many file types in FTP archives and they are usually tagged with an extension denoting the format. Some examples:
=============================================================================== Extension | File type | Data type || Extension | File type | Data type ==========|===============|===========||===========|================|========== .txt | ASCII/text | ASCII || .doc | ASCII/text | ASCII .com | program | binary || .exe | program | binary .ps | postscript | binary || .Z | (UNIX)compress | binary .zip | (DOS)compress | binary || .gif | graphics | binary ===============================================================================If you are retrieving a binary file, type binary at the ftp> prompt before getting the file. To return to ASCII format, type ASCII at the ftp> prompt before getting the file. If you use Kermit to download files from CUNIX to your machine, start up Kermit on CUNIX with the kermit -i option, which signifies that you are transmitting a file in binary format, not in text format.
