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
make clean
make build
make install

7. reboot
