Partition a sequence of disk drives for LVM with fdisk

So, I'm using a CentOS VM in VirtualBox, and created four new disks in the SCSI controller. The VM created the folders: /dev/sda /dev/sdb /dev/sdc /dev/sdd Using a 'for loop' all disks are partitioned for LVM.

mount starting sector of the partition we want to mount

Assuming we have a disk image, created by dd if=/dev/sda of=image.dd we can check the image's partition layout with fdisk -ul image.dd, then substitute "x" with starting sector of the partition we want to mount. This example assumes that the disk uses 512Byte sectors

mount -o loop,offset=$((512*x)) /path/to/dd/image /mount/path

Partition a new disk as all one partition tagged as "LInux LVM"

This is a bit hacky, but if you're setting up a bunch of new LUNs, it can save a bunch of time. Also check out sfdisk. The fdisk will fail if, for example, a partition table already exists.

Export OPML from Google Reader

Save the Top 2500 commands from commandlinefu to a single text file

Use default value if unassigned

Will use variable value (for variable $my_dir, in this case), an assign a default value if there is none.

Quick directory bookmarks

Set a bookmark as normal shell variable $ p=/cumbersome/path/to/project To go there $ to p This saves one "$" and is faster to type ;-) The variable is still useful as such: $ vim $p/ will expand the variable (at least in bash) and show a list of files to edit. If setting the bookmarks is too much typing you could add another function $ bm() { eval $1=$(pwd); } then bookmark the current directory with $ bm p

Create a bunch of dummy files for testing

Sometimes I need to create a directory of files to operate on to test out some commandlinefu I am cooking up. The main thing is the range ({1..N}) expansion.

list block devices

Shows all block devices in a tree with descruptions of what they are.

Lookup autonomous systems of all outgoing http/s traffic

List alive hosts in specific subnet

Works on any machine with nmap installed. Previous version does not work on machines without "seq". Also works on subnets of any size.

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

I finally found out how to use notify-send with at or cron

The simplest way to do it. Works for me, at least. (Why are the variables being set?)
