[lcd4linux] Help required pls...

[Mark H. <ma...@ha...>]

 

I hope this is read by someone,. as I have noticed the web page has been
filled with spam,..

 

My question is as follows:-

 

Trying to produce an output of the following format

 

"/(16.1%)     Qstore(54.2%)   Mythstore(67.2%)

 

To show disk usage on a media Linux system

 

Have used the following line as a base

 

expression a=(((statfs('/', 'bavail'))*4)/1024/1024);b=(((statfs('/',
'bavail'))*4)/1024/1024);c='/ '.' '.a.'MB  /root/ '.b.' MB'

 

and adapted to suit,.. and got to the following:-

 

expression a=(((statfs('/', 'bfree'))*4)/1024/1024);b=(((statfs('/',
'blocks'))*4)/1024/1024);c=(100-((a/b)*100));d='/('.c.'%)'

 

Which nicely displays      "/(13.0472%)"   ..  Perfect, almost!! Just Too
many digits after dp.

 

How do I remove the unnecessary decimal placed digits,.. I have evaluated
sprint, sed, and bc,.. but I think I may be barking up the wrong tree,.. I
am certainly struggling on how to tie these commands into a lcd4linx
expression. I have worked out precision is not the way to go.

 

Is any learn'd person of the team able to help me, and put me out of my
frustration.

 

Kind Regards

 

Mark
