Hi...

Thanks for ur reply.

I am doing yum local repository. When i go to mirror.centos.org and look at the os , updates or addons repository it doesn't tell me the size of the repository.


But like in os directory there are files which have the size so i copy all the sizes for each every file in os directory and add them and come out of the size.

How i can get size of the centos repository?

thanks,

Hi...

Sorry to reply late.

thank you so much radoulov for replying back to me. Smilie
======================================

your awk command help me that's was i was looking for to get total in Megabytes. I assume same command will give me total in Gigabytes if the all the size in Megabytes.

As i am new to shell script now. I will work on a script so i can get total size of centos repository for example 1) base 2) updates 3) addons and 4) extras. No mirror list repositories have size of each repo on their site...i haven't found any of them.

Will post my script later this week.

Thanks everyone for help.
