how to create tar and compress at the same time
 
Hi,

I always create the tar then I compress it, as a two steps. How can I do this in one step?

Code:
xyz - is a directory which is under /var/log

Step 1. tar -cvf /home/sam/march27_backup.tar /var/log/xyz
Step 2. gunzip march27_backup.tar
I did this and I get error message.

Code:
tar -cvf /home/sam/march27_backup.tar /var/log/xyz |gzip -c
Thank you.

Hi,

Tar's -z (--gzip) option can do that:
Code:
tar -zcvf /home/sam/march27_backup.tgz /var/log/xyz
BTW: The -j (--bzip2) can be used to use bzip2. There are more:
Code:
tar --help
too see all options.

Hope this helps.

tar can handle the compression itself (using external programs). Have a look at the options -j, -z and -Z in the man page, they work for creating and extracting archives (although not necessary for extracting, tar recognizes compression automatically in that case).
