It always helps to consult the man pages (although I have to admit tar's is quite complex).
For compressing, just add the z option.
For excluding directories, add their names to the exclude file.
for the compressing, is it similiar with

Some will accept the -z flag as part of the tar command, some will not and you have to pass the output to a compression program afterwards, but the default compression programs can vary depending on your OS too, e.g. compress, gzip, bzip, etc.
If none of the above posts have given you an answer, please post your OS and version and we can find the appropriate process for you.

I have a tar file that contains multiple .Z files. Hence I need to issue a tar command followed by a gzip command to fully extract the files. How do I do it in a single command?
What I'm doing now is
tar xvf a.tar (this will output 1.Z and 2.Z)
gzip -d *.Z (to extract 1.Z and 2.Z) (9 Replies)
Is it possible to untar a file so it's size reduces while it uncompresses its contents. I have limited space on my mount point and was wondering if we can untar as a stream in other words the size of tarball reduces as it uncompresses the contents.
Thanks (5 Replies)

rdup-tr
RDUP-TR(1) rdup RDUP-TR(1)NAME
rdup-tr - transform rdup output
SYNOPSIS
rdup-tr [OPTION]...
DESCRIPTION
Transform rdup output into something else. Where something else can be a tar, cpio, pax archive or another rdup stream.
The rdup archive must be given on rdup-tr's standard input.
You can select multiple types of output (-O flag), but you must be aware that you may loose some information in formats other than rdup's
own, see the table below.
You may also supply rdup-tr with only a list of pathnames, this can be selected with the -L flag.
The following table shows what happens with the output depending on the input.
0 OK
D delete information is lost
H hardlink information is lost
| |
output | tar,cpio,pax | rdup
input | |
------------- | ------------- | ------
rdup | D | 0
filelist | DH | H
| |
OPTIONS -L Select list input format. Normally rdup-tr accepts rdup output, with this option you can give it a list of path names. Note: with
list input rdup-tr will `stat()` each file.
-O Output format. This can be 'tar', 'cpio', 'pax' or 'rdup'. It defaults to 'rdup'.
-X key Read the encryption key from the file key and encrypt all paths with Blowfish and this key and iv. After the encryption the binary
data is converted into ASCII using an URL safe (Section 4 of RFC 3548) version of base64 encode.
The encryption key must be on the first line and the key size must be 16 and 8 bytes for the iv, so 24 in total.
-Y key Read the decryption key from the file key and decrypt all paths with Blowfish and this key. Before the encryption the paths are con-
verted to binary by using an URL safe version of base64 decode.
-c Force output to the tty. Normally rdup-tr wants to see it's output redirected.
-v Be more verbose.
-V Print rdup-tr's version.
-h A short help.
EXAMPLES
The following is possible
rdup -Pgzip -Pmcrypt,-f,KEY,-c /dev/null /home |
rdup-tr -O tar -X<(echo secret) | gzip >
my-home-zipped-crypted-pathcrypted-tar.gz
That is: all files under /home are gzipped and encrypted on a per file basis (first line). Further more, all pathnames are Blowfish
encrypted (second line) with the key 'secret'. This is put in a tar file, which is then compressed, resulting in the final output (final
line).
Creating a compressed and encrypted tar archive out of a full rdup dump might be done as follows
rdup -Pgzip -Pmcrypt,-f,KEY,-c /dev/null /home |
rdup-tr -O tar > my-home-zipped-and-crypted.tar
Or even pack and unpack it on the fly
rdup -Pgzip -Pmcrypt,-fKEY,-c /dev/null /home | rdup-tr -Otar |
ssh user@remotehost tar xvCf /tmp -
Or encryption with openssl
rdup -Popenssl,enc,-e,-des-cbc,-k,secret /dev/null /home
Or, compressing with gzip, encrypting with openssl and then compressing the entire archive yet again
rdup -Pgzip -Popenssl,enc,-e,-des-cbc,-k,secret /dev/null /home |
gzip > my_compressed_encrypted_rdup_archive.gz
Recreating the original rdup output, which can be fed to rdup-up.
gunzip -c my_compressed_encrypted_rdup_archive.gz |
rdup-tr -Popenssl,enc,-d,-des-cbc,-k,secret -Pgzip,-d >
my_rdup_archive
rdup-up < my_rdup_archive -t /tmp/restore
Notice the reversal of the -P options.
EXIT CODE
rdup-tr return a zero exit code on success, otherwise 1 is returned.
