as prog:
cd /usr2
git pull origin master

1.  copy control files to new directory:
mkdir control.yg-9.11.4
cp -rp control/* control.yg-9.11.4/
Make these the default
ln -sfn control.yg-9.11.4 control


2. unpack new version


su
cd / 
tar xzpvf /home/prog/fs-9.11.4.tgz
cd /usr2 
ln -sfn fs-9.11.4 fs
exit


3. Now as prog 
4. build fs
cd fs
make

5. re-build st
cd /usr2/st
make rmdoto rmexe all

6. as root
cd /usr2/eremotectrl
make clean
make build
make install

7. reboot

8. Log in as oper
cd /usr2/control

added the following to skedf.ctl:

* DBBC target values for IF counts in set-up procedure, up to 4
* values for up to four IFs, in order, this will cause an error
* in IFx=... command execution if used for DBBC DDC versions
* before v101
* default is nulls if not present
dbbc_if_targets  25000 25000 35000 35000
*--------------------------------------------------------------
* DBBC BBC TPI target levels
* has no effect for DDC versions before v103
* default is null if not present
dbbc_bbc_target 16000

cd /usr2/proc
modified station.prc as follows:
     (F) This step is only for stations with DBBCs that are updating
         from previous version of 9.11.x, x=0, 1, or 2. Three changes
         are needed to the station.prc library:

         (i)   Please insert the command "bbc_gain=all,agc" at the end
               of your SETUPA procedure.  This command is a "no-op"
               for DDC version less than v103, but including it is
               recommended that be added for future backward
               compatibility.  For stations with v104 or higher, as
               additional parameter specifying the target count level
               can be added if it is desired, e.g.,
               "bbc_gain=all,agc,16000"

         (ii)  Add the procedure "BBC_LEVEL" to your station.prc
               library.  This can probably done most easily with the
               following commands:

                 cd /usr2/proc
                 cp /usr2/fs/st.default/proc/bbc_level.prc .
                 pfmed
                   st,bbc_level::bbc_level,bbc_level
                   ex
                 rm bbc_level.prc

         (iii) This step is only for stations with non-continuous cal and has
               two parts.

               (a) Edit the CALTSYS_MAN procedure and insert the command
                   "bbc_gain=all,man" right after the "IFMAN" command.

               (b) Edit the CALTSYS procedure and insert the command
                   "bbc_gain=all,agc" right after the "IFAGC" command.
