Bash script run app and get context console while app running

 You can run an application from a Bash script and get access to the application's console (stdout and stderr) while it's running. This is often useful for monitoring the application's output in real-time. Here's how you can achieve this:


```bash

#!/bin/bash


# Start your application in the background

./your_application &


# Capture the process ID (PID) of your application

APP_PID=$!


# Continuously display the application's output (stdout and stderr)

tail -f /dev/null


# Optionally, you can add other commands or logic here


# When you're ready to stop the application, you can use:

# kill $APP_PID

```


In this script:


1. `./your_application &` starts your application in the background, and the `&` symbol is used to run it as a background process.


2. `APP_PID=$!` captures the process ID (PID) of the application.


3. `tail -f /dev/null` is used to continuously display the output of the application. By using `/dev/null` as the input file, you effectively get a real-time display of any output from the application. You can replace `/dev/null` with the path to the application's log file if applicable.


4. You can add other commands or logic after the `tail` command to perform additional tasks while the application is running.


5. To stop the application, you can use `kill $APP_PID`. This sends a termination signal to the application.


Keep in mind that this script will keep running until you manually terminate it. You can stop the script and the application by pressing Ctrl+C in the terminal.


Replace `./your_application` with the actual command or path to your application. The script will run the application in the background and continuously display its output.

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
