How to find the UUID of a disk drive in Linux

March 25, 2015 by Jay Versluis

There are two ways I know of which will print the UUID of all disk drives attached to the current system: blkid /dev/sr0: UUID=”2014-12-02-19-30-23-00″ LABEL=”CDROM” TYPE=”iso9660″ /dev/sda1: UUID=”ae55a647-3c57-4ab5-9651-1389703fe6fe” TYPE=”ext4″ /dev/sda2: UUID=”bMtCfO-zpDU-7U1t-DcHg-Fe9p-Cy1K-Se0e1I” TYPE=”LVM2_member” /dev/sdb1: UUID=”0982ce66-537a-497b-baaf-99136594f3e8″ TYPE=”ext4″ /dev/mapper/VolGroup-lv_swap: UUID=”8f0652a8-d79b-453f-aa2d-0ff0b5d0ae7b” TYPE=”swap” /dev/mapper/VolGroup-lv_root: UUID=”5afc1b25-e6cd-45b2-ad20-69f0fed323b9″ TYPE=”ext4″ /dev/mapper/VolGroup-lv_home: UUID=”94e15e98-1cff-49a9-b76a-a8f3a948e2ea” TYPE=”ext4″ or ls -la /dev/disk/by-uuid total 0 drwxr-xr-x. 2 root root 160 … Read more

How to disable the ultra annoying Startup Sound on Mac OS X

March 23, 2015 by Jay Versluis

I passionately *H*A*T*E* the startup chime that my Mac makes when I switch it on. At least on my MacBook, if the volume is turned down before I shutdown, the system restarts silently. I guess it’s somehow linked to the internal speakers. Sadly on my Mac Mini this approach doesn’t work: due to the lack … Read more

How to prevent your MacBook from sleeping when you close the lid

March 14, 2015 by Jay Versluis

There’s a built-in command line tool in every Mac called caffeinate that prevents your computer from going to sleep, even when the lid is closed. This is the default behaviour if an external monitor is attached, but if that’s not the case, MacBooks just go to sleep as soon as you close the lid. While … Read more

How to view Plesk websites even if your domain does not resolve to your server

March 9, 2015 by Jay Versluis

It’s never good if your server is working fine, but the domains that resolve to it are down for one reason or another. This has happened to me TWICE this year already, and both times it was out of my hands (yes @ENOM, I’m looking at you). Many of my clients use websites for data storage, … Read more

How to specify FTP credentials in command line scripts

March 7, 2015 by Jay Versluis

It’s easy to establish an FTP connection using the ftp command from the Linux Command Line. Sadly this command does not accept login credentials as parameters – which means that if we use it in a script, our script will pause and wait for us to type those credentials in manually. Not really suitable for … Read more

Getting started with Jekyll on CentOS 7

March 5, 2015 by Jay Versluis

It’s not quite as easy to get up and running with Jekyll as the Quick Start Guide makes it sound. But it’s not super difficult either – if explained from one human to another. Here’s how I got Jekyll working on a vanilla CentOS 7 instance. Installing some necessary packages Before we can install Jekyll … Read more

How to mount EXT4 partitions on Android Jelly Bean

March 8, 2015March 5, 2015 by Jay Versluis

I was racking my brains over how to mount an SD card formatted with anything other than FAT32 on my Android device. Jelly Bean and Kit Kat automatically mount FAT32 partitions, but they seem to ignore native Linux file systems – which Android clearly understands. Apparently there’s a $1.54 app on the Play Store that … Read more

The Debian Experience: Cheat Sheet for CentOS and Fedora users

March 3, 2015 by Jay Versluis

I’ve just installed a LAMP stack on my Nook Tablet using Debian. However I’ve been using CentOS since 2008 and I’m so used to how things are done there that it was a bit of a culture shock doing relatively simple things “on the other side”. It’s like a country whose language you don’t speak … Read more
