The number of Github repositories that I end up maintaining in one way or another ends up growing week by week. And keeping all of the descriptions and settings up to date in sync can be painful todo by hand.
A little while ago I migrated my addwiki project to use a monorepo, and thus needed to bulk update all of the github repository descriptions. While doing so I made use of the github cli and created a single bash script to let me configure all of the repositories at once.
Assuming you already have the github cli install and configured getting started with this is easy.
The below command is one of many in my bash script for repo configuration. This sets a description, homepage and various other flags that I want to be consistent across repositories.
gh api --method PATCH repos/addwiki/addwiki \
--field description='Monorepo containing all addwiki libraries, packages and applications'\
Recently I found myself altering some virtual images for loading onto a qemu machine. I wanted to increase the disk space on the root partition, but couldn’t find any straightforward guides. So here is a little guide for future me, and anyone else.
libguestfs is a set of tools for accessing and modifying virtual machine (VM) disk images. You can find details in the docs.
apt-get install libguestfs-tools
Create a new resized image
First you need to create a new empty image of the size that you want.
For me that is 20GB
truncate -s 20G ./out.img
Then use virt-resize to expand the existing disk to fill all of the space in the new image that we created. (virt-resize docs)
virt-resize --expand /dev/sda1 ./vm.img ./out.img
Verify it worked
libguestfs-tools also provides a way to view file system information by only using the image file. (virt-filesystems docs)
virt-filesystems --long --parts --blkdevs -h -a ./out.img
You’ll see something like this:
Name Type MBR Size Parent
/dev/sda1 partition 8320G /dev/sda
/dev/sda device - 20G -
