Follow the instructions:

1. Go to your home directory by typing

   cd
   

2. Build your home page directory by typing

   mkdir ~/public_html
   

3. Give execute permission (not read and write) to your directories for your group members (g) and other people (o) by

   chmod go+x-rw ~/. 
   chmod go+x-rw ~/public_html
   

4. Go to public_html by

   cd ~/public_html
   

5. Edit a file and call it index.html. You need an index.html file for all the directories under public_html.
6. Make the files in your directory readable by commands like

   chmod go+r-xw *.html
   chmod go+r-xw *.jpg
   

   (Remember: all the files you want other people to read should be readable for other people; all the directories should be executable.)
7. The URL of your web page is

   http://physics.nyu.edu/~yourusername
   or
   http://sciweb.nyu.edu/~yourusername
   

8. Go to tutorials to learn more about HTML, editors on Unix systems, etc.
9. Type following on IO or SCIRES

   man chmod
   

   to learn more about chmod.
10. You can always learn cool HTML tricks by using the "View->Page source" on your web browser, however, before you try them, read How not to design junk Web pages at www.tuxedo.org/~esr/html-hell.html.
11. Email webmaster@physics.nyu.edu if you are ready to link your page from Physics web page.

Suggestion: It is a good idea to create your web pages in another directory or event on another machine. Test them with your web browser (IE or Netscape can read local HTML files as web pages), then publish them by moving the files to the ~/public_html directory with cp, scp, ftp or fetch (If you write HTMLs on Mac). See tutorials.
