Ex-Mode is mostly for performing the same action on a number of files. Say you have 25 .html files all with:
<a href="/home.html"> ...
Instead of opening each one of those, you could use Ex-mode to change it all to index.html:
vim -E -s bob.html <<-EOF %substitute/home.html/index.html/ update quit EOF

You should really quote some relevant text from the previous post...
Also, the "eof" marker in a heredoc does NOT have to start in the first column, if you use this syntax, leading tabs will be stripped:
some_command <<-eof blah blah blah eof
Note the "-e" after the "<<"...
