sed command not working right

Didn't know of a better title for the thread.. But anyways.. I am using the command sed to remove all periods from a file name. But the result is that it removes the first character of the file name...Here is an example

sh-3.00$ echo filename.text | sed 's/.//g'

sh-3.00$ echo filename.text | sed 's/.//'
sh-3.00$ uname -a
Linux 2.4.31 #6 Sun Jun 5 19:04:47 PDT 2005 i686 unknown unknown GNU/Linux

In the first example with the global flag(g) it puts spaces in for every character, in the second example without the global flag it jst removes the first character..

Whats up with this? Im pretty sure im using sed right, how can I just remove the periods from the filenames?

The . is an expression that matches a single character. If you want to match a literal '.' you need to escape it. The following returns filenametxtext:
echo filename.txt.ext | sed -e 's/\.//g'
I assume you have the sed expression wrapped in a loop that mv's files?
