Instance reachability troubleshooting

### 1. **Networking Issues**
– **Security Groups:** Ensure that the security group attached to your instance allows inbound traffic for SSH (port 22) and other relevant ports.
– **Route Table:** Check if the route table for the subnet has a proper route to the internet gateway.
– **Elastic IP (if applicable):** If you're using an Elastic IP, ensure it is associated with your instance.

### 2. **Instance-Level Issues**
– **Operating System Crash:** The instance's operating system might have encountered an error, causing it to become unresponsive.
– **Disk Issues:** The root volume might be corrupt, preventing the system from booting correctly.
– **Excessive Resource Usage:** High CPU, memory, or disk usage might be causing unresponsiveness.

### 3. **Connectivity Issues**
– **Firewall Rules:** Firewalls on the instance itself (e.g., iptables, ufw) could block access.
– **Network ACLs:** Ensure that Network ACLs associated with your subnet are not blocking inbound or outbound traffic.

### Steps to Resolve the Issue

#### **Step 1: Verify Security Group and Networking**
– Go to the **EC2 Dashboard** → **Instances** → Select your instance → **Security Groups**.
– Ensure the rules allow SSH (port 22) and other required ports.
– Check the **Route Table** under **VPC** → **Route Tables** to confirm a route to the internet gateway.

#### **Step 2: Check System Logs**
– Use the AWS Console to view the system logs:
– Navigate to **Instances** → Select your instance → **Actions** → **Monitor and troubleshoot** → **Get system logs**.
– Look for errors that might indicate what caused the failure (e.g., kernel panic, disk errors).

#### **Step 3: Stop and Start the Instance**
– Sometimes, simply restarting the instance can resolve temporary issues:
– Stop the instance, wait for a few minutes, then start it again.

#### **Step 4: Create a Temporary Recovery Instance**
If the issue persists:
1. Detach the root volume from the problematic instance.
2. Attach it to another instance as a secondary volume.
3. Mount the volume and investigate logs, fix corrupted files, or remove problematic configurations.
4. Reattach the root volume to the original instance.

#### **Step 5: Rebuild the Instance**
– If recovery is not possible, consider launching a new instance and attaching the backup or root volume of the previous instance.

#### **Monitoring**
– Check the **Instance Status Checks** in the EC2 Dashboard frequently to ensure it's resolved.

### 1. **Check Current Remote URL**
Run the following command to see the current remote URL:

git remote -v

This will display something like:

origin  https://old-url.com/user/repo.git (fetch)
origin  https://old-url.com/user/repo.git (push)

### 2. **Change the Remote URL**
Use the `git remote set-url` command to update the remote URL:

git remote set-url origin NEW_URL

Replace `NEW_URL` with the new remote repository URL.

#### Example:
If your new repository URL is `https://github.com/user/new-repo.git`, the command would be:

git remote set-url origin https://github.com/user/new-repo.git

### 3. **Verify the Change**
Check to confirm the remote URL was updated successfully:

git remote -v

You should now see:

origin  https://github.com/user/new-repo.git (fetch)
origin  https://github.com/user/new-repo.git (push)

### 4. **Push to the New Remote (if needed)**
If the new remote is empty and you're moving an existing repository:

git push -u origin main

Replace `main` with the name of your branch if it's different.

### 1. **Choose a Default Reconciliation Strategy**

To avoid seeing this message in the future, configure a default pull behavior using one of the commands below:

#### Merge (default behavior):
This merges the remote branch into your local branch, keeping both branches' history intact.

git config pull.rebase false

#### Rebase:
This applies your local commits on top of the fetched changes, creating a linear history.

git config pull.rebase true

#### Fast-Forward Only:
This pulls changes only if the local branch is directly behind the remote branch (no divergent history). If there are conflicts, it will abort.

git config pull.ff only

To apply the setting globally for all repositories, add `–global`:

git config --global pull.rebase false

—

### 2. **Resolve for the Current Pull Command**

You can also specify the desired behavior directly with the `git pull` command, without setting a permanent configuration:

– **Merge**:

git pull --no-rebase

– **Rebase**:

git pull --rebase

– **Fast-Forward Only**:

git pull --ff-only

—

### 3. **Reconcile Divergent Branches**

If your branches are already divergent, you need to decide how to reconcile the changes:

#### Merge (default):
This will merge the remote branch into your local branch.

git pull --no-rebase

#### Rebase:
This will reapply your local changes on top of the fetched branch.

git pull --rebase

—

### 4. **Inspect Changes Before Pulling**
If you're unsure, fetch the changes first and review them:

git fetch
git log ..origin/branch-name

Replace `branch-name` with the name of your branch.

This allows you to decide how to proceed after inspecting the commits.

Let me know if you need help reconciling specific branches!

—

### **1. Commit the Deletion**
If you intended to delete the file, commit the changes:

git commit -m "Remove vite.config.js"

This will permanently record the deletion in your repository's history.

—

### **2. Unstage the Deletion**
If you want to undo staging the deletion, run:

git restore --staged vite.config.js

This will unstage the deletion and restore the file in the working directory.

—

### **3. Restore the File**
If you accidentally deleted the file and want to bring it back:

git restore vite.config.js

This restores the file to its last committed state.

—

### **4. Undo Both Staging and Deletion**
If you want to fully revert the changes (unstage and restore the file):

git restore --staged vite.config.js
git restore vite.config.js

—

### **5. Check the Current Status**
To confirm the changes after any action:

git status

Let me know if you need further assistance!

1. The file `vite.config.js` was **renamed to `shareyourthoughts/vite.config.js`** in `HEAD` but **deleted** in the commit being rebased.
2. The file `shareyourthoughts/vite.config.js` was **modified** in `HEAD` but **deleted** in the commit being rebased.

### Steps to Resolve the Conflict

—

#### 1. **Inspect the Conflict**
Run the following command to see the conflicting files:

git status

It will show the files with conflicts, like:

both modified:   shareyourthoughts/vite.config.js

—

#### 2. **Decide on Conflict Resolution**
You have three main options for each conflicting file:

1. **Keep the version from `HEAD`**:
Retain the file changes from your current branch.

git restore --source=HEAD --shareyourthoughts/vite.config.js

2. **Use the version from the conflicting commit (`9020245`)**:
Accept the changes from the rebased commit and delete the file.

git rm shareyourthoughts/vite.config.js

3. **Manually merge changes**:
Open the file in an editor, resolve conflicts manually, and save it.

—

#### 3. **Mark the Conflict as Resolved**
Once you've resolved the conflict, mark it as resolved by staging the files:

git add shareyourthoughts/vite.config.js

If you deleted the file, use:

git rm shareyourthoughts/vite.config.js

—

#### 4. **Continue the Rebase**
After resolving all conflicts, continue the rebase process:

git rebase --continue

—

#### 5. **Abort the Rebase (if necessary)**
If you decide you don’t want to continue with the rebase, you can abort it and return to the state before the rebase started:

git rebase --abort

—

#### 6. **Verify Resolution**
After finishing the rebase, ensure everything is correct:

git status

### **1. Using `rm` Command (Linux/macOS/WSL)**
To delete all files and subdirectories in a folder, use:

rm -rf /path/to/folder/*

#### Explanation:
– `rm` – Command to remove files and directories.
– `-r` – Recursively delete subdirectories.
– `-f` – Force deletion without confirmation.
– `*` – Matches all files and directories in the specified path.

—

### **2. Retain the Folder but Empty It**
If you want to keep the folder itself while deleting everything inside:

rm -rf /path/to/folder/*
rm -rf /path/to/folder/.[!.]*

#### Why the Second Command?
The second command deletes hidden files and directories (dotfiles), as `*` does not match files starting with a dot.

—

### **3. Deleting Contents via `find`**
For more control, you can use `find`:

find /path/to/folder -mindepth 1 -delete

#### Explanation:
– `-mindepth 1` – Ensures the root folder itself is not deleted.
– `-delete` – Deletes each file and subdirectory.

—

### **4. Using `File Explorer` (Windows GUI)**
1. Open the folder in File Explorer.
2. Select all contents (Ctrl + A).
3. Press Delete or Shift + Delete to delete permanently.

—

### **5. For Docker Volumes**
If you are inside a Docker container and want to clear a folder:

docker exec -it container_name bash -c "rm -rf /path/to/folder/* /path/to/folder/.[!.]*"

—

### **Warning**
– Be cautious with `rm -rf`, as it permanently deletes files.
– Double-check the path to ensure you're not deleting unintended data.

### **Syntax**

mv /source-folder/* /destination-folder/

### **Steps**
1. **Move All Visible Files and Directories**:

mv /source-folder/* /destination-folder/

– This moves all visible (non-hidden) files and directories from `/source-folder/` to `/destination-folder/`.

2. **Move Hidden Files and Directories**:
Hidden files and directories (those starting with a dot, e.g., `.env`) are not moved with `*`. To include them:

mv /source-folder/.* /destination-folder/

**Note**: Avoid moving `.` and `..` (current and parent directories). You can exclude them with:

mv /source-folder/.[!.]* /destination-folder/

3. **Move Everything (Visible + Hidden Files)**:
Combine both commands for complete coverage:

mv /source-folder/* /source-folder/.[!.]* /destination-folder/

—

### **Examples**
1. **Basic Example**:
Move all files and subdirectories from `temp/` to `backup/`:

mv temp/* temp/.[!.]* backup/

2. **Docker Container**:
If working in a Docker container, you can move files like this:

docker exec -it container_name bash -c "mv /source-folder/* /source-folder/.[!.]* /destination-folder/"

3. **Preserve Source Folder**:
After moving, the source folder remains empty. To delete it:

rmdir /source-folder

—

### **Important Notes**
– **Wildcards (`*`)**: Match all files and directories but not hidden ones.
– **Hidden Files (`.[!.]*`)**: Matches files starting with a dot except for `.` and `..`.
– **Avoid Data Loss**: Ensure no files in the destination folder have the same name unless overwriting is intended.
