What is the idiomatic way to do the following
- tar to stdout
- read this tar output from stdout and extract to some other folder.
My solution is
tar --to-stdout .. | tar -C somefolder -xvf -
But may be there is more idiomatic way to do it.
GNU tar uses stdio by default:
rsync is also popular.
Just adding another use-case here. I had a large directory structure on a system nearly out of disk space and wanted to end up with a tar.gz file of the directory structure on another machine with lots of space.
This saves on network overhead and means you don't have to tar on the other side in case you'd wanted to use rsync for the transfer instead.
