If you want to exclude certain filetypes from the directory when creating a tar archive use the –exclude parameter for tar
tar -zcvf filename.tar.gz abc_direc/ –exclude=’*.zip’ –exclude=’*.gz’ –exclude=’*.log’ –exclude=’*.pdf’
tar -zcvf wha_clean.tar.gz public_html/ –exclude=’*.zip’ –exclude=’*.gz’ –exclude=’*.log’ –exclude=’*.pdf’ –exclude=’*.jpg’ –exclude=’*.JPG’ –exclude=’error_log’ –exclude=’*.tar’
