Is it possible to add caching to a pipe?
cat blah | in_RAM_cache_here -s SIZE | something else
I'm doing what is essentially a cat (*) from a DVD directly to an NFS share. It looks like the two media (DVD and NFS) have very different read / write behaviors, speeds and timings, and the overall process is not as fast as possible. So I was wondering if some kind of cache inbetween might be beneficial. Except, I have no idea whether there's already a command line tool that can accomplish that (and I'm not so desperate as to try and implement one myself).
(*) - it's actually tccat, part of the transcode package, but the idea is the same. Here's the actual command:
n=14 for i in `seq -w 1 ${n}`; do echo "${i} out of ${n}" tccat -i /dev/dvd -T 1,${i} > ch${i}.mpeg done sync ls -lh
