How To Check Whole Genome With Bigwigsummary ?

Hi,

I have question about bigwigsummary tools ,

I have my start and end positions and my bigwig file but I want to check whole genome instead of chromosome by chromosome Is there any option to use this tool in that way ?

I know that for each chromosome I have to use :

bigWigSummary -type=X bigwigfile chrN start end datapoints

I want to check from chr1 to chrX.

Thanks in Advance.
