How do you replace a file name prefix in bulk with a bash script?

What I've managed to do so far is append it. 

#!/bin/bash
for f in *
do 
mv "$f" "File${f##/}"
done

File names consist of 3 random letters followed by 3 numbers. I need to replace the 3 letters with "File".

Got it

#!/bin/bash
for f in *
do 
newName=File"$(echo "$f" | cut -c4-)"
mv "$f" "$newName"
done

Apparently I'm not supposed to comment to say thank you so I'll just add it here. Thank you, I'll use Ignacio's method.

You can use:

newName=`echo $f | sed 's/^[a-z]\{3\}/File/'`
mv $f $newName

Then you need to strip the three letters.

"File${f#???}"
