For example, say you want to create an archive of a directory to back it up: tar -zcf /some/backup/folder/yoursite_www_$(date +"%m_%d-%Y_%H:%M").tar.gz /home/someuser/somesite/public_htmlSo that'll create an an archive of everything located in /home/someuser/somesite/public_html. Great. But what if you have a folder with large files in it that you want to exclude from being backed up? For example: /home/someuser/somesite/public_html/bigfiles ? How would you exclude that from being archived?
