Configure LCDd.conf for LC16M VFD LCD 16×2 screen

I wanted to reinstall my old XBMCuntu distro with new version from kodi.tv and I have downloaded latest available iso file from here.

Since my Silverstone LC16M case has 16×2 VFD display it is normal that I want to use it together with all the multimedia keys. In order to get them working kernel module imon must be loaded.

To support LCD in Kodi you will need addon XBMC LCDproc but before installing the plugin you need to have lcdproc package installed and configured. Continue reading “Configure LCDd.conf for LC16M VFD LCD 16×2 screen”

Remove SCSI faulty spare hdd from RAID with mdadm

I manage a lot of servers with simple software RAID1 configuration. One of the disks started to fail notably on partition sdb8, so I had to set all other partitions to failed status before removing and replacing the disk:

mdadm --manage /dev/md0 --fail /dev/sdb5
mdadm --manage /dev/md3 --fail /dev/sdb7
mdadm --manage /dev/md1 --fail /dev/sdb6

After this my /proc/mdstat looked like this:

cat /proc/mdstat
Personalities : [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
md2 : active raid1 sdb8[1](F) sda8[0]

 bitmap: 3/3 pages [12KB], 65536KB chunk

Find files in sub-directories and unpack them in place

I have a lot of zip and rar archives in various sub-directories, which I wanted to extract but to leave the files in their sub-directories.

I have used for a long time this command to search for files and extract them in working directory:

find ./ -iname "*.zip" -print0 | xargs -0 -I {} 7z -y x {}

Which works OK if you want your files all to be extracted to the directory where you started the find command. But to leave files in their own folder this command was not appropriate.

It seems that find command has this neat flag called “-execdir” which does exacty that what I wanted, so here are few examples:

Find all zip files in sub-directories and unzip them in place using unzip:

find ./ -iname "*.zip" -execdir unzip -o '{}' ';'

Find all rar files in subdirectories and unzip them in place using unrar:

find ./ -iname "*.rar" -execdir unrar e '{}' ';'

The same using 7zip would look like:

find ./ -iname "*.zip" -execdir 7z -y x '{}' ';'

and

find ./ -iname "*.rar" -execdir 7z -y x '{}' ';'

Later on if you want to delete your zip and rar files and only leave the contents you can use similar command from where I have started.

For example to delete all rar archives that are named .rar, r00, r01 … r0x you can use:

find ./ -iname "*.r??" -print0 | xargs -0 -I {} rm {}

and similar you can can use to delete zip files, but please make sure that you don’t have zip files in your zip archives that you do not want to delete:

find ./ -iname "*.zip" -print0 | xargs -0 -I {} rm {}
