ubuntu maverick lib64

On Ubuntu maverick: 

there is not /usr/local/lib64 link to /usr/local/lib 

so 

sudo ln -s /usr/local/lin /usr/local/lib64 

ubuntu sudo

it seems that the path environment is not influenced by changes in /etc/profile when using sudo 

old ubuntu (maverick), new R

It would work (with color) when there is a more after grep.

grep files from results by find

 find /var/ftp/mp3 -name "*.mp3" -type f -exec chmod 644 {} \;

 This command changes the permissions of all files with a name ending in .mp3 in the directory /var/ftp/mp3. The action is carried out by specifying the option -exec chmod 644 {} \; in the command. For every file whose name ends in .mp3, the command chmod 644 {} is executed replacing {} with the name of the file. The semicolon (backslashed to avoid the shell interpreting it as a command separator) indicates the end of the command. Permission 644, usually shown as rw-r--r--, gives the file owner full permission to read and write the file, while other users have read-only access. In some shells, the {} must be quoted.

Using Linux

You can also use dd command from Linux itself (it removes partition table):
# dd if=/dev/null of=/dev/sdX bs=512 count=1

Just remove MBR, without the partition table (see comment below):
# dd if=/dev/null of=/dev/sdX bs=446 count=1

Replace /dev/hdX with your actual device name such as /dev/hda. Use fdisk -l command to find out device name:
# fdisk -l
