Compile and install oh my Zsh

1. Preface

oh-my-zsh Is based on zsh A set of beautification tools , It also provides many themes and plug-ins .github Introduce

2. What's the use

It is possible for me to view git Branches are more intuitive , In addition, its powerful completion function

Or more intuitively check whether the return value of the previous command is 0

Of course, this function is only the tip of the iceberg , There are also many functions to explore , It is not only a beautification tool, but also a sharp tool that can improve work efficiency ！

3. How to install

Because it's on the company server, I don't have root Authority and sudo jurisdiction , So we can only adopt the method of compiling and installing .
oh-my-zsh rely on zsh, and zsh Depend on and depend on ncurses, So first compile and install ncurses.

3.1 Compilation and installation ncurses

Before compiling, you need to import some environment variables , The function of importing environment variables is to compile later zsh When you can find ncurses Link library

export CXXFLAGS="-fPIC"
export CFLAGS="-fPIC"
export NCURSES_HOME=$HOME/.local  #  Your own  ncurses  Catalog 
export PATH=$NCURSES_HOME/bin:$PATH
export LD_LIBRARY_PATH=$NCURSES_HOME/lib:$LD_LIBRARY_PATH
export CPPFLAGS="-I$NCURSES_HOME/include" LDFLAGS="-L$NCURSES_HOME/lib"

You can write it to ~/.bashrc in , then source ~/.bashrc once .

Start downloading and compiling

wget http://ftp.gnu.org/pub/gnu/ncurses/ncurses-6.1.tar.gz  #  download ncurses
tar -xzvf ncurses-6.1.tar.gz  #  decompression 
cd ncurses-6.1
./configure --prefix=$HOME/.local/ --with-shared --without-debug --enable-widec  #  Specify the path configure
make -j4 && make install 

After successful compilation and installation, it will be in Home directory .local Under the folder ,bin Directory is the executable file ,lib Stored in the directory for zsh Use ncurses Link library of , There are also some header files in include Under the folder , It can be used for development , But none of this is necessary care.

3.2 Compilation and installation zsh

wget https://jaist.dl.sourceforge.net/project/zsh/zsh/5.9/zsh-5.9.tar.xz 
tar -xvf xvf zsh-5.9.tar.xz
cd zsh-5.9
./configure --prefix=$HOME/.local/  # --prefix Is to specify the directory after compilation and installation , That is, after the final compilation is successful, it will be installed in  $HOME/.local/bin  Catalog 
make -j4 && make install

because $HOME/.local/bin The directory defaults to PATH In the environment variables , So type zsh Can be called to the compiled zsh Of
Here we are zsh and ncurses Have been compiled and installed successfully

3.2 install oh-my-zsh

sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

Wait for the installation to succeed
This will automatically enter zsh, Next start input zsh You can enter .

4. Replace oh-my-zsh The theme

oh-my-zsh There are many themes , It can be $HOME/.oh-my-zsh/themes notice :

Its theme changes , You can modify $HOME/.zshrc The contents of the document

For example, the theme I use here is agnoste

5. Start automatic entry zsh

It is generally used on the Internet here chsh Command to replace the default shell, But for no root jurisdiction , Or it is obviously bad for users who do not want to modify the global configuration .
So here we use modify $HOME/.bashrc file , Add... To the last line zsh That's all right. , The purpose of this file is to shell It will be automatically executed when starting , So every time ssh When the connection enters, it will automatically enter zsh

6. Other ways to install software

because apt Installing the software requires root jurisdiction , So we can use apt download deb, Then decompress deb package , Finally, the The pressurized file is put in .local Under the directory
for example install htop

apt download htop  
dpkg-deb --fsys-tarfile htop_2.1.0-3_amd64.deb | tar xvf -  #  decompression deb
cp -r  ./usr/* .local  #  unzipped usr All folders and files in the directory   Copied to the .local Next 

This installation method is suitable for less dependent software , If there are many dependencies, you need to download multiple deb package , Then move to the corresponding directory , This method is much more convenient than compiling and installing
