Sameer Joshi — Wed, 04 Oct 2023 14:47:13 GMT

Managing multiple Git accounts on a single Linux machine can be a common scenario, especially for developers who contribute to different projects or work with various organizations. Using SSH keys to authenticate with Git hosts is a secure and efficient way to manage these accounts. In this tutorial, we'll walk you through the steps to add multiple Git accounts in Linux using SSH keys.

First locate the ssh directory

 cd ~/.ssh

Generate SSH key pair(generate ssh for each acc you want)

ssh-keygen -t ed25519 -C "youremail@github"

This command generate the ssh key pair at ~/.ssh

Configure SSH for each github account by creating a config file.

touch ~/.ssh/config

Inside the config file, add the following

Host github.com
HostName github.com
User git
IdentityFile ~/.ssh/name_of_ssh_key_generated_earlier

For each account you want to add, repeat the steps above and change the IdentityFile to the new ssh key generated for that account and change the host to your choice
Go to github.com/settins/new/ssh and add the ssh key from the file that have .pub extension generated for the desired account
To test if the SSH is working, run the following command
To test if the SSH is working clone a private repo using ssh

 git clone git@:/.git

Add alias to the cloned repo using the ssh to make it simple each time you want to push or pull
```
git remote add origin git@:/.git
```
Add some changes to the cloned repo and push it to the remote repo and check if the changes are reflected in the remote repo

Setting Permission in Ubuntu to Read and Write in Other Partition

Sameer Joshi — Sat, 12 Mar 2022 13:39:19 GMT

After installing Ubuntu in ssd as my main daily driver it was running pretty fast and smooth compared to dual booting with windows. After installing Ubuntu in ssd i got my hard drive laying around only for file storage. But I got one problem with my harddrive, I could not write any files nor read files from it. I have so many files in that drive. It was in NTFS partion. After searching for a while I found out it shoud be converted into Ext4 or FAT file system so linux can read or write files to it.

So to convert it into Ext4 or FAT:

Open Disks App in Ubuntu
Go to the HDD section top left cornor as show in above screenshot
Select the partition you want to format. (in my case labeled as linuxStorage)
Rename the volume as your liking and set the type to ExT4 or FAT
The Press Next
After the format is complete open files and in the navigation bar click other location and double click to mount the partition you have just formatted and renamed.
After Mounting the drive open the terminal using Ctrl + Alt + T
Type the following command :
```
lsblk
```
The above command will display block device which are files that represent devices such as hard drives, RAM disks, USB drives etc

in my case i would do the following

sudo chmod 777 /media/sameer/linuxStorage

but in your case you should replace with your username and disk partition

The list of permission are as follows:

7- Full(Read, Write & Execute)

6- Read and Write

5- Read and Execute

4- Read Only

3- Write and Execute

2- Write Only

1- Execute Only

0- None
