Batch to create semaphore

After receiving a FILENAME_yyyymmdd .txt file from vendor I need a Unix batch script to accomplish the following:
1.      Copy the original file to the "archive"
2.      Rename original incoming file FILENAME_yyyymmdd .txt to FILENAME.txt
3.      FILENAME.sem - create a semaphore file. Nothing needs to be in here. It is
                 simply a flag to the batch that indicates the file retrieval is complete.
4.              Alert relevant parties via email
The most important pieces of that are created the .sem file and transferring/renaming the FILENAME_yyyymmdd .txt  to FILENAME.txt file.

#Assuming that $filename is FILENAME_yyyymmdd.txt
cp $filename /path/archive/
#Strip off _ and everything past _
temp=$(echo $filename | sed 's/\(.*\)_.*/\1/')

#move
mv $filename $temp.txt
#create blank file
echo > $temp.sem

Note that the above will only strip the last _ and everything following it, so filename can have _ characters and it will still work. If you want to strip the first _ and everything after, you could use something a lot simpler like:
temp=$(echo $filename | sed 's/_.*//')
