hi @Harald Pretl I am getting fatal error what command need to give here and tell me path is correct or not?

check what you typed, the link is not a command.

echo "#######################################################"
echo "#----------------Installing ngspice-------------------#"
echo "#######################################################"
#install ngspice 
sudo apt-get install -y libtool
git clone <https://git.code.sf.net/p/ngspice/ngspice> ngspice_test
cd ngspice_test
git pull
git checkout pre-master
./autogen.sh
./configure --with-x --enable-xspice --disable-debug --enable-cider \
	--with-readline=yes --enable-openmp 
make
sudo make install
cd ..

Use this to install ngspice

my path is correct or not ?

you first command is correct but the link is incorrect

how i can correct it ? what i need to give?
