Adding Syntax Highlighting to Linux less

Install source-highlight:

 sudo apt-get install source-highlight  

Add the following two lines to~/.bashrc

 export LESSOPEN="| /usr/share/source-highlight/src-hilite-lesspipe.sh %s"  
 export LESS=' -R '  

Now source files opened with less will be nicely syntax highlighted. source-highlight supports many languages - see

 source-highlight --lang-list  

for a full listing.
