You can try the below link, but we do not endorse any of them:

also
PuTTY is a FREE
implementation of Telnet and SSH for Win32 platforms:

We do not allow Telnet, it is way to dangerous/unsecure.
We only allow SSH, which is Encrypted Telnet and enables you
to do the EXACT same things that Telnet would allow. It is
SECURE.
SSH can be requested through our Web Support Center if it is
not already set up on your account. We will turn it
on in 24 hours or less from the time it is requested.

DOS Command Unix Equivalent
cd cd /
dir ls
copy cp
move mv
del rm
deltree rm -r
mkdir mkdir
rmdir rmdir
A few notes on the Unix filesystem.
-CAUTION: Unix gives very few warning messages about
manipulating files. Eg. if you
tell the system to delete all files or a large directory
tree it will.
-Unix uses the slash '/' whereas dos uses the backslash ''
-Filenames have no limit on their length.
-Files may have multiple extensions greater than 3
characters each
(eg. backup.domains.012398)
Useful Unix Commands
ps=Show processes. Displays all active programs you are
currently running.
df=Device free. Shows hard drive usage.
who=Who. Shows all users currently logged onto this server.
finger=Finger. Similar to who. May be given a username as a
parameter in order to get information about that user. For
example finger
.
ctrlz=Stops the current program/job.
ctrlc=Stops and kills the current program.
kill=Kill. Requires a process number as a paramenter in the
form of kill %
.
For example kill%1. USE WITH CAUTION, or better yet, simply
always do a ctrl c.
su=Set User. Allows you to have root access on systems where
you do not recieve it automatically at logon.
SU will prompt you to enter the root password. You may also
use the command to 'assume' the identity of
any system user. For example, su jean. This can be useful
for testing purposes.
./=Run. "./" is the unix equivalent of a run
command. The syntax is: ./
tar=tar. Tar is a program which combines directories and
their files into one single file archive. This archive is
typically compressed. It is useful when relocating a user or
domain to another server. The
two most common usages of this command are illustrated
below:
tar cvfz filename.tar.gz * (This will create an archive of
all files and directories branching off of this directory,
inclusive. Tar will copy symbolic links, but not what they
link too.)
tar xvfz filename.tar.gz (This explodes the tarred file
created above)
rcp=Remote Copy. This command allows you to copy a file from
one server to another, without having to manually ftp it.
The syntax is:
rcp filename
:
eg. rcp filename.tar.gz tlg.yourwebhost.com:/www/htdocs/jean/
grep=grep. Grep allows you to search a file or even a whole
directory for a specified string. The syntax is
grep
. Eg. grep jean /etc/domainalias. This would look for the
string 'jean' in the file /etc/domainalias.
ftp=File Transfer Protocol. FTP is a program used to
exchange files between servers. It is invoked by typing ftp.
It can accept a hostname as a parameter, eg. ftp
yourwebhost.com.
telnet=Telnet. Telnet is a program used to logon to another
server. It is typically invoked with the following syntax:
telnet
.
lynx=Lynx. Lynx is a text based web browser. It is useful
for checking to see that new accounts have been properly
setup. Lynx is typically invoked with a url as a parameter.
For example: lynx espn.com
Misc: Symbolic Links. A symbolic link, is a link to a file
or directory. For example you can typically access the
directory /usr/home/jean by typing cd /home/jean. This is
because a symbolic link exists which
directs /usr to /usr/home. All new accounts have symbolic
links in their /usr/home/username directories.
One of these is to www. The symbolic link www points to
/www/htdocs/domainname. Thus, if
a user logs on, and types cd www, he will actually be in the
directory /www/htdocs/domainname.
VI: A Brief Summary
VI stands for visual editor. It is the most commonly used
means of editing files on unix servers. It is typically
invoked by typing: vi
. If the file exists it will be opened for editing. If the
file does
not exist, it will be created (note it must be saved before
it will actually exist).
Commands
esc=command mode
i=insert before
a=insert after
shift+a=insert at end of line
shift+g=goto end of file (special use: While in command mode
type a line number, then hit shift+g. This will goto the
line number typed)
ctrl+f=scroll forward one page
ctrl+b=scroll back one page
/=search. (special use: After typing / enter the string you
wish to search for and press enter.)
:=While in command mode, pressing colon allows you access to
the following commands:
w=write (saves file)
q=quit (exits vi)
wq=write quit(saves file and exits vi)
q!=exits vi without saving
(escape returns to command mode)

Another VERY EASY text editor in UNIX is:
pico
So, to edit a file you would type:
pico filename
