Using tar with parallel compression using pigz with multi cores processor   $ tar cvf MYDIRECTORY.tar.gz --use-compress-prog =pigz MYDIRECTORY   In a similar way, you can list the contents of the tarball like this:  $ tar tvf MYDIRECTORY.tar.gz --use-compress-prog =pigz Or you can extract the tar like this: $ tar xvf MYDIRECTORY.tar.gz --use-compress-prog =pigz  

Grep /var/log/messages by date without leading zeros   date= `date --date=" yesterday " +%b\ %e`   grep $date / var / log / messages
