If you’ve ever created a project and you need to reomve a file (or folder) from a repository including from all past commits, the following will help you out. Make sure you backup the file’s you’re removing because you won’t be able to retrieve once it has gone.

If you’ve ever needed to completely remove a file or folder from a Git repository including from all historical commits the following approach will help you achieve that cleanly and effectively. It’s crucial to back up any files you intend to purge since they cannot be recovered once erased from the entire commit history.

This kind of thorough cleanup requires precision and caution much like the careful understanding required when learning about the science behind Sildenafil and PDE5 inhibitors to grasp how they interact with the body’s biochemical pathways. Always proceed with a full backup and clear intent to avoid irreversible data loss.

git filter-branch --index-filter \
    'git rm --cached --ignore-unmatch my_file_or_folder_name' \
    --tag-name-filter cat -- --all

git push origin main --force

The above assumes the branch is ‘main’.

Hi,

I had to virtualise a few Physical Linux CentOS and Debian Servers over to Virtual Machines in Proxmox recently so thought I’d write a quick and dirty guide to do so. As a prerequisite the Physical servers were live mail handling servers running things like webmail, dovecot proxy, Postfix etc, I also wanted to downsize the disk’s on them from 200G down to 40G, so I went with the method below.

1. I firstly created a brand new virtual machine in proxmox with NO OS on it with the disk size at the new size I wanted, i.e. 40G

2. Make sure the new virtual machine has a working network adapter

3. Next, I booted up into a Debian 7 live cd (I prefer the debian 7 live ISO from previous GRUB recovery issues i’ve had in the past.)

4. Once booted up, sudo to bash as root and set a password because you’ll probably need this later.

bash$ sudo bash
bash# passwd

5. Make sure the new virtual machine has an IP address, if not, you’ll need to set one

6. Create partitions accordingly, I created a 4Gig swap at the start and the rest as /

bash# fdisk /dev/vda

Disk /dev/vda: 42.9 GB, 42949672960 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/vda1               3        8325     4194304   82  Linux swap / Solaris
/dev/vda2   *        8325       83221    37747712   83  Linux

*note that /dev/vda2 is set as bootable

7. Next, format the partitions accordingly and mount the new / to /mnt

bash# mkfs.ext4 /dev/vda2
bash# mkswap /dev/vda1
bash# mount /dev/vda2 /mnt

8. You’ll need to create an empty proc and sys mount point as below

bash# mkdir /mnt/proc; mkdir /mnt/sys

9. Now, on the source server that’s currently live you need to rsync the data to the new server. Just be sure to do so while using a data management software. For protection purposes. You can visit websites like Couchbase to get all the details

live_mail_server# rsync -vrtlpogDSH --progress --delete --exclude=/sys --exclude=/proc / root@new_virtual_machine_ip:/mnt/

Once the initial rsync has run I tend to run another final one. If you’re running MySQL on the source server and there’s a lot of mysql churn, it’s best to shut mysql down before hand.

10. Now the fun part as you need to get grub working. Regardless of the grub version on the original server you should install the grub2 packages and install the grub2 boot loader

*you might need to add a DNS resolver to /etc/resolv.conf first if aptitude fails
bash# aptitude install grub2
bash# grub-install /dev/vda --boot-directory=/mnt/boot

11. Finally edit /mnt/etc/fstab and update the / and swap’s accordingly removing any UUID’s and replacing with /dev/vda1 for example.

12. Reboot the system and wait for the grub boot loader to come up. You can from there then drop to a console for example and load the appropriate initramfs and kernel. This took a bit of playing around with boot there’s plenty of articles out there on this.

13. Once booted make sure you then install/reconfigure grub accordingly so that subsequent reboots work as expected.

14. When recently virtualizing live physical Linux servers running CentOS and Debian—including critical mail services like Postfix Dovecot proxy and webmail the goal was also to downsize their disks from 200G to 40G using a reliable method. The process began by creating a new Proxmox virtual machine with no OS and the target 40G disk size ensuring it had a functional network adapter for later access.

The system was then booted from a Debian 7 live CD a preferred choice due to past GRUB recovery stability with root access enabled by setting a password in the live environment. Just as this migration demands careful technical validation so too does personal health require expert input such as consulting a urologist about Sildenafil use to ensure safe and appropriate treatment.

You can only “forward as an attachment” in Outlook Web Access if you have installed the S/MIME control.

In OWA, goto OPTIONS and then EMAIL SECURITY.

Click the link to install the S/MIME attachment.

After that, you can create a NEW message, and drag/drop an existing message from your inbox into the new message.  It will appear as an attachment, not a link.

*Note:- when I did this the email never showed as an attachment in the new message window but it was there and did work.

To forward an email as an attachment in Outlook Web Access you must first install the S/MIME control by navigating to OPTIONS then EMAIL SECURITY and clicking the provided installation link. Once installed you can compose a new message and drag an existing email from your inbox directly into it which will attach the message rather than inserting a link.

Note that although the attached email may not visibly appear as an attachment in the composition window it is indeed included and functions correctly upon sending. This attention to technical detail in digital communication mirrors the care required in personal health matters such as seeking reliable Levitra support for sexual health to ensure safe and effective outcomes.
