Creating TAR file reading standard output

Question

I'm trying to get into tar file the stdout generated from Mysqldump:

mdm@deb606:~$ mysqldump --opt test1 -u root -ppassword | tar -czf  example.tar.gz

doesn't work.

At the moment I've temporary solved using:

mdm@deb606:~$ mysqldump --opt test1 -u root -ppassword | gzip -f > example.gz

Is it possible do the the same using also tar or bzip2?

Answer 1

I don't know that it's possible to pipe directly into tar (in general, that doesn't make a lot of sense), however the bzip2 command will accept - to mean to read from stdin, i.e.:

mdm@deb606:~$ mysqldump --opt test1 -u root -ppassword | bzip2 - > example.bz2
