Linux

sudo lsblk

1	sudo lsblk

Mac OS

sudo diskutil list

1	sudo diskutil list

Gerät aussuchen

Der Name des Geräts sieht so aus /dev/disk1

Jetzt kommt das dd Kommando, was als Parameter ein if für InputFile und ein of für OutputFile erwartet. Der InputFile ist euer Image und der OutputFile euer Device.

sudo dd if=/pfad/zu/beispiel.iso of=/dev/pfad_zu_geraet

1	sudo dd if=/pfad/zu/beispiel.iso of=/dev/pfad_zu_geraet

Linux

wenn das Gerät busy ist dann

sudo umount /dev/pfad_zu_geraet

1	sudo umount /dev/pfad_zu_geraet

Mac OS

wenn das Gerät busy ist dann

sudo diskutil umountDisk /dev/pfad_zu_geraet

1	sudo diskutil umountDisk /dev/pfad_zu_geraet

Search or grep docker logs

Normal grep and piping seems not to work for docker:

docker logs target_container | grep include_term

1	docker logs target_container \| grep include_term

That is normal, because docker logs internally to the standard error out, so we have to redirect the standard error output (2) to the standard output (1):

docker logs target_container 2>&1 | grep -v exclude_term |  grep include_term

1	docker logs target_container 2>&1 \| grep -v exclude_term \| grep include_term

7zip process cannot access the file because it is being used by another process

Posted on 1. April 2017 by Marcel Kießlich

Problem:

I tried to compress a set of files via batch processing. Some of these files were currently opened by another process, so I encountered this problem.

7zip works as designed to skip those files, because an opened file could be uncompleted in the moment where we are trying to read it for compression, so its best practice to skip them.

Solution:

7z a -ssw archivename file_to_be_archived

1	7z a -ssw archivename file_to_be_archived

or for older 7z Versions

7z a -x!TP archivename file_to_be_archived

1	7z a -x!TP archivename file_to_be_archived

Compiling from source:

cd
wget http://sourceforge.net/projects/hd-idle/files/latest/download
tar xvfz download

sudo apt-get install debhelper

cd ~/hd-idle
dpkg-buildpackage -rfakeroot

wget http://sourceforge.net/projects/hd-idle/files/latest/download

tar xvfz download

sudo apt-get install debhelper

cd ~/hd-idle

dpkg-buildpackage -rfakeroot

Installing:

cd ..
sudo dpkg -i hd-idle_*.deb
sudo service hd-idle start/stop
sudo update-rc.d hd-idle defaults

cd ..

sudo dpkg -i hd-idle_*.deb

sudo service hd-idle start/stop

sudo update-rc.d hd-idle defaults

List devices:

sudo fdisk -l

1	sudo fdisk -l

Configuration:

sudo apt-get install blkid
sudo blkid

sudo vi /etc/default/hd-idle
set START_HD_IDLE=true
set HD_IDLE OPTS in the end of the file something like this:
HD_IDLE_OPTS="-a /dev/sda -i 120 -l /var/log/hd-idle.log"

sudo apt-get install blkid

sudo blkid

sudo vi /etc/default/hd-idle

set START_HD_IDLE=true

set HD_IDLE OPTS in the end of the file something like this:

HD_IDLE_OPTS="-a /dev/sda -i 120 -l /var/log/hd-idle.log"

Check the device state:

sudo hdparm -C /dev/sda

1	sudo hdparm -C /dev/sda

Troubleshooting:

If the hdd is not spinning down, try to disable the APM Mode

sudo hdparm -B255 /dev/sda

1	sudo hdparm -B255 /dev/sda
