the first tar sends the tarball to stdout, the second reads it from
stdin. your shell connect those two together.

the output of `ls -alR` is not suitable for what you want.
`tar tvf` with find(1) is your best bet.

Could someone step through what this is doing?  I thought you could use "-"
(stdin?) only once on a command line.  My question was more about using
less CPU time with something simiar to "find" or `ls -alR | sort`

du, find/xargs/sort, and MP3.tar

2002-10-22 Thread Peter Leftwich 
Here's a doozy for you.  I'm trying to compare a directory called MP3/ with
a huge file called MP3.DONE0415021909MPT.tar -- the idea being to make sure
the contents are similar (I've touched new files in the MP3/ directory
since untarring, so they won't be exactly the same...)

I tried some commands along the lines of these:

# du -hs MP3/
1.6GMP3/

# du -hs MP3.DONE0415021909MPT.tar
1.2GMP3.DONE0415021909MPT.tar

Erg, wait this proves nothing; I'd have to untar and THEN du -hs :(

Then I thought I'd get crafty and `tar tvf MP3.DONE0415021909MPT.tar >
the-tarfile.out` thinking I could later run things through `sort` but I am
hung up on how to get similar output that shows the contents of MP3/.

# find MP3/ -type f | wc -l
OR?
# find MP3/ -type f -exec ls -al {}\; | more
OR?
# find MP3/ -type f -print | xargs or something like that | sort...

Could one of you /\/\aster$ work some unixiacal magic on my task?  =^)

It soothes my soul to know you care.
