问题
Im using Ubuntu 13.04 (Linux) I have installed node, and npm. With npm I downloaded less via terminal.
Im using this on my simple HTML/CSS project. pure frontend. its not a Ruby or nodejs project.
And when I do
lessc styles.less styles.css -x -w
in terminal, it compiles and compresses the code, but doesn't watch the file for changes, since Im expecting LESS to auto compile and refresh the page automatically. So, if I do any changes in my styles.less, every-time I have to go to terminal and enter the command to compile the less css.
Also, the compiler does NOT even show any compile errors even if I add anything on purpose, but in that case it doesn't compiles.
Please guide me on how to achieve the above. This is my first day with LESS CSS.
回答1:
If you type lessc help you will see that there is no argument -w or --watch. What you can do is to use a build system like GruntJS with an extension like grunt-contrib-watch and have that monitor your less files and build the css on change.

I did this with help of @Oil on ubuntu forums.
In terminal,
1. install sudo apt-get install inotify-tools
then simply CD to the css folder. and run below lines together:
while inotifywait -r styles.less; do lessc -x styles.less styles.css; done
