BashBlaze-7-Days-of-Bash-Scripting-Challenge

Task 1: Comments:

A comment is a piece of text in a program or script that is ignored by the compiler or interpreter. It is used by developers to leave notes, explanations, or other information.

The shebang (#!) is used at the beginning of a script to specify the interpreter that should be used to execute the script.

Task 2: Echo

The echo command is used to display messages on the terminal. Your task is to create a bash script that uses echo to print a message of your choice.

Output:

Task 3: Variables

Variables in bash are used to store data and can be referenced by their name. Your task is to create a bash script that declares variables and assigns values to them.

Output :

Task 4: Using Variables

Variables can hold different types of data. Common data types include:

Types of Variables:

• Integer: Used to store whole numbers (without decimals).

• Example: age = 30

• Float/Double: Used to store decimal numbers (with floating points).

  Example: price = 19.99

  String: Used to store sequences of characters (text).

  Example: name = "Alice"

  Boolean: Used to store True or False values.

  Example: is_active = True

  Array/List: Used to store a collection of multiple values (can be of the same or different types).

  Example: fruits = ["apple", "banana", "cherry"]

  Dictionary/Associative Array: Used to store key-value pairs.

  Example: person = {"name": "Alice", "age": 30}

Output:

Task 5: Using Built-in Variables

Task 6: Wildcards

Wildcards are special characters used to perform pattern matching when working with files. Your task is to create a bash script that utilizes wildcards to list all the files with a specific extension in a directory.

Wildcards are special characters used in command-line interfaces and programming to represent one or more characters in strings or filenames. They provide a way to match patterns rather than specific strings, making it easier to handle groups of files or data without specifying each one individually.

Common Wildcards in Unix/Linux Shells:

Asterisk (*): Represents zero or more characters.

Example: *.txt matches all files with a .txt extension (e.g., file1.txt, document.txt, notes.txt).

Example: file* matches any file that starts with "file" (e.g., file1, file2.txt, file_example).

Question Mark (?): Represents a single character.

Example: file?.txt matches files like file1.txt, fileA.txt, but not file10.txt or file.txt (since the last one has no character where the question mark is).

Brackets ([]): Used to specify a range or set of characters.

Example: file[1-3].txt matches file1.txt, file2.txt, and file3.txt.

Example: file[a-c].txt matches filea.txt, fileb.txt, and filec.txt.

Exclamation Mark (!): Inside brackets, it can be used to specify a negation.

Example: file[!0-9].txt matches files that start with "file" followed by a character that is not a digit
