How to update TikZ library

Sometime you need to update your TikZ library to contain new library files. Then you can do like this,

1. Go to TikZ Build to find out the latest built version for TikZ.
2. Download the tar package and extract it to some temporary place.
   

   
   ls pgfCVS2010-07-25_TDS.zip
   mkdir pgfInstallFile
   unzip pgfCVS2010-07-25_TDS.zip -d pgfInstallFile/
   doc/ tex/
   

   
   
3. Go to /usr/share/texmf/tex/
   


4. You have to replace the old pgf package file with the new file. You can copy
   

   
   cp -r $pgfInstallFile/tex/context/pgf/  /usr/share/texmf/tex/context/pgf/  ;
   cp -r $pgfInstallFile/tex/generic/pgf/  /usr/share/texmf/tex/generic/pgf/  ;
   cp -r $pgfInstallFile/tex/latex/pgf/    /usr/share/texmf/tex/latex/pgf/  ;
   cp -r $pgfInstallFile/tex/plain/pgf/    /usr/share/texmf/tex/plain/pgf/  ;
   

   
   
5. After that, you can update the tex file configuration,
   

   
   texhash ;
