Use the tab key. To match either space or tab, you could use [ ]
(space and tab inside the [ ])

If you are using vi to write the above script you can a least see the tab
characters by [ESCAPE] (to get to the command mode) and then:
:set list
This will show the tabs as ^I and will show [RETURN] as $
:set nolist
to turn off the feature.

Sure, one method in vi (sorry) command (or movement, whatever) mode, enter
:1,$s/^>// ...where, reading from the bottom

You may want to substitue "/^> /" (notice space after >) for the string to
be substituted. If I recall there is a space after the > in reply mail.
Otherwise the result will be indented one space.
Hope it helps...jc

Here are two methods with sed:
sed -e '/^SV[0-9][0-9]/s/ //' infile
sed -e 's/\(SV[0-9][0-9]\) /\1/' infile
actually, on the actual sample shown, this would work too:
sed -e 's/\([0-9][0-9]\) /\1/' infile

Translating your sed command: Change any 4-letter string consisting
of the the letters "CV" followed by any two characters (including
spaces) to itself. Not surprising that it does nothing. Nothing is
exactly what you told it to do. Try something like:
s/\(SV[0-9][0-9]\) /\1/
Translation is left as an exercise for the student.

Hello,
Try
sed 's/^\(SV[0-9][0-9]\) /\1/'
Here meaning of various regular expressions are as following:
^ : Beginning of line
\(..\): Braced regular expression, remembers whatever was matched between
the braces and can be referred as \1 \2 in search as well as replacement
pattern
[0-9]: Match any character between 0 to 9
