Tar and Gzip in one command

Easier way

tar -czvf osp2.tar.gz --exclude=*.png --exclude=*.jpg --exclude=*.pdf --exclude=*.zip --exclude=*.gz --exclude=*.tar osp

here i am creating .gz archive from osp directory. For some I needed multiple exclude for each file extension. Some one can digg into this. Tougher way Example of how to gzip a single file

tar cvf - foofoo.sql | gzip > foofoo.tar.gz

Example of how to gzip an entire directory:

cd a1 tar cvf - . | gzip > ~/backup-020916.tar.gz
