So this is a dumb one but it took me longer than expected to find an answer.
So say I want to make a local copy of a wordpress site. I want to tar up all the files to download because downloading the files one by one will take hours and hours.
Assuming a directory structure like
I would normally go to /www and do
tar -zcvf mysite.tar.gz public_html
That gets everything…much faster to ftp.
But on some of our sites, we wind up with a BIG cache and I really don’t need all that stuff. In our case the cache is at:
So how to exclude the cache files? There’s an –exclude flag for tar but it seems finicky. Turns out it has to be the first parameter, at least for me and some others.
So this worked for me:
tar --exclude='public_html/wp-content/cache' -zcvf mysite.tar.gz public_html
This did NOT work for me
tar -zcvf mysite.tar.gz public_html --exclude='public_html/wp-content/cache'
Nor did this:
tar -zcvf --exclude='public_html/wp-content/cache' mysite.tar.gz public_html
–exclude seemed to only work when it came first after the tar command.
