5 min readIn Golang, iterating through a string involves accessing each character of the string one by one. Here's how you can do it:To start, you need to import the strings package. import ( "strings" ) Create a variable of type string and assign the string you want to iterate through. str := "Hello, World!" Use the len() function to find the length of the string. strLength := len(str) Iterate through the string by using a for loop and the strings.

5 min readThe MariaDB password on Linux is typically stored in the MariaDB configuration file, which is usually located at /etc/mysql/mariadb.conf.d/50-server.cnf or /etc/mysql/my.cnf. Within this configuration file, you will find a section called [client], where the password is stored under the parameter "password". However, it is important to note that the actual password is encrypted and not visible in plain text.

6 min readIn Go, passing a map as a parameter to a function is quite simple. You can include the map as an argument in the function declaration and use it within the function's body. Here is an example of how to pass a map as a parameter in Go: func myFunction(myMap map[string]int) { // Access and interact with the map here // ... } In this example, myFunction is declared with a single parameter myMap, which is a map of string keys and integer values (map[string]int).

9 min readTo check if a file exists on a remote Linux system, you can use several command-line tools such as ssh, scp, and sshpass. Here's a step-by-step guide:Open the terminal on your local Linux machine.Use the ssh command to connect to the remote Linux system. Replace user with your remote username and remote_ip_address with the IP address or hostname of the remote system. ssh user@remote_ip_address Enter the password associated with your remote account when prompted.

11 min readIn Golang, it is possible to pass functions as arguments to other functions. This allows for creating more flexible and reusable code by treating functions as variables.To pass a function as an argument, you need to define the function parameter with the appropriate function type. The syntax for function types is func(<parameter list>) <return type>. For example, func(int) int represents a function that takes an integer argument and returns an integer.

7 min readTo find files that are larger than a certain size in Linux, you can use the find command along with the -size option. Here's how you can do it:Open the terminal in Linux. Use the following syntax: find /path/to/directory -type f -size + -exec ls -lh {} \; Replace /path/to/directory with the actual directory where you want to search for files. specifies the size filter.

9 min readIn Golang, it is possible to pass an interface as a parameter to a function. This allows for greater flexibility and reusability in code.To pass an interface as a parameter, you need to define the function signature with the interface type specified as the parameter.

10 min readTo use the # symbol in a Linux terminal command, it typically represents a comment. Comments are lines of code or text that are ignored by the system and are meant for human readers to provide explanations or additional information about the command.When using the # symbol in a terminal command, it is usually followed by text or code that describes what the command does or provides any necessary context.

6 min readIn Golang, it is possible to pass a function as a parameter to other functions. This allows for extensibility and flexibility in designing code. To pass a function as a parameter, you need to follow these steps:Declare a function with the appropriate signature that matches the function you want to pass as a parameter. The signature includes the function name, input parameters, and return type (if any).

4 min readTo create a link to a script on Linux, you can use the ln command.The general syntax for creating a link is: ln -s <source_file> <destination_link> Here, <source_file> represents the path to the script you want to link, and <destination_link> represents the desired name and location for the link.For example, to create a symbolic link to a script called myscript.sh, located in /path/to/script/myscript.

6 min readTo create a YAML file in Golang, you can follow these steps:Import the required packages: import ( "io/ioutil" "github.com/go-yaml/yaml" ) Define a struct that represents the structure of the YAML file.

8 min readManaging Linux users with Kubernetes involves several steps and configurations. Here's an overview of the process:Authentication: Kubernetes supports various authentication mechanisms like X.509 certificates, static passwords, or token-based authentication. You need to configure the authentication method to verify the Linux users' identity within Kubernetes. User Role Assignment: Kubernetes relies on Role-Based Access Control (RBAC) to govern user access to cluster resources.
