How to download a file that redirects to another file?

Question about downloading a file that redirects to another file. If you encounter a situation where a file you want to download redirects to another file, you can typically address it with the following approaches:


1. **Follow the Redirect Manually**: You can use the `curl` or `wget` command-line tools to follow the redirection and download the target file. For example, using `curl`:


   ```bash

   curl -L -o output_file https://original_url

   ```


   The `-L` option tells `curl` to follow redirects, and `-o` specifies the output file name.


2. **Use a Web Browser**: If the redirection happens on a website, using a web browser is often the simplest way. When you click the link to download the file, the browser will typically handle any redirects and start downloading the final file.


3. **Check HTTP Headers**: Use the `curl` command with the `-I` option to retrieve the HTTP headers of the original URL. This will show you the location of the target file. For example:


   ```bash

   curl -I https://original_url

   ```


   Look for the `Location` header in the output to find the new URL.


4. **Modify the User Agent**: In some cases, websites may use user agent detection to determine if you're using a browser. You can modify the user agent string to make the server think you're using a browser. For example:


   ```bash

   curl -A "Mozilla/5.0" -L -o output_file https://original_url

   ```


   This emulates a common browser user agent.


5. **Using `wget`**: With `wget`, you can also follow redirects and download the target file. For example:


   ```bash

   wget --max-redirect=10 -O output_file https://original_url

   ```


   The `--max-redirect` option specifies the maximum number of redirects to follow, and `-O` specifies the output file name.


6. **Check for JavaScript Redirection**: In some cases, redirection is performed using JavaScript. Command-line tools like `curl` and `wget` might not handle JavaScript-based redirection. In such cases, using a web browser is often the most practical solution.


Remember to replace `original_url` with the actual URL of the file you want to download. By using these methods, you should be able to handle redirection and download the target file successfully.

bad character U+002D '-' in my helm template

 In Helm templates, the hyphen character (`-`) can sometimes be treated as a reserved character, particularly when defining values or labels. To include a hyphen character in a Helm template without issues, you can use one of the following approaches: 1. **Quoting the Hyphen:**    You can enclose the hyphen in double quotes, like this:    ```yaml    key: "-"    ```    This way, Helm will interpret the hyphen as a string rather than an operator. 2. **Using Backticks:**    If you need to use the hyphen within a Go template function or inside backticks, you can escape it with a backslash (`\`), like this:    ```yaml    value: `{{ .Values.someField | printf "%s \\-" }}`    ```    The backslash prevents Helm from interpreting the hyphen as a special character. 3. **Variable Assignment:**    Assign the value to a variable and use it. For example:    ```yaml    {{- $hyphen := "-" }}    key: {{ $hyphen }}    ```    This way, you can use the variable `$hyphen` wher

GitLab pipeline stopped working with invalid yaml error

 When your GitLab pipeline has stopped working with an "invalid YAML" error, it means there's a problem with your `.gitlab-ci.yml` file. This could be due to syntax errors, incorrect indentation, or other issues in your pipeline configuration. Here's how to troubleshoot and resolve this issue: 1. **Check for Syntax Errors**:    Carefully review your `.gitlab-ci.yml` file for any syntax errors. Common issues include missing colons, indentation problems, or mismatched quotation marks. Use a YAML linter or an online YAML validator to identify and correct syntax errors. 2. **Indentation**:    YAML relies heavily on proper indentation. Make sure that all lines within the same block have consistent indentation (typically using spaces, not tabs). Incorrect indentation can cause YAML parsing errors. 3. **Dashes and Lists**:    Ensure that you use the correct syntax for lists (arrays) in YAML by starting each item with a dash (`-`). Be consistent with your use of dashes throug

How do I add a printer in OpenSUSE which is being shared by a CUPS print server?

 To add a printer in openSUSE that is being shared by a CUPS print server, you can use the following steps: 1. **Ensure CUPS Client is Installed:**    Make sure your openSUSE system has the CUPS client tools installed. You can install them using the following command:    ```bash    sudo zypper install cups-client    ``` 2. **Discover Available Printers:**    Use the `lpinfo` command to discover available printers on your CUPS print server. Replace `cups-server-hostname` with the hostname or IP address of your CUPS server:    ```bash    lpinfo -v -h cups-server-hostname:631    ```    This command should list the printers shared by the CUPS server. 3. **Add a Printer:**    Use the `lpadmin` command to add a printer. Replace `printer-name` with the name of the printer you want to add and `printer-uri` with the URI obtained from the `lpinfo` command:    ```bash    sudo lpadmin -p printer-name -E -v printer-uri    ```    For example:    ```bash    sudo lpadmin -p MyPrinter -E -v socket://cu
