Welcome to this comprehensive series of videos where we will be giving solutions and explanations for various BASH challenges from Hackerrank. In this video, we will be addressing 4 tasks, including "'Uniq Command #1" (🤍 "'Uniq Command #2" (🤍 "'Uniq Command #3" (🤍 "'Uniq Command #4" (🤍 Our goal in this series is to document my thought process and solutions, and to focus on concepts and ideas rather than details. I will also be highlighting the differences between BASH and popular programming languages like Python and JavaScript. BASH is a powerful command-line interface for interacting with an operating system. It's a shell, and the most popular one. It can be used directly in the terminal or in scripts, which are text files containing a series of instructions. BASH is particularly useful for tasks such as text processing, file operations, connecting multiple programs, and system maintenance. It is also portable, working by default on many platforms. uniq is a command line utility in Unix-like operating systems that is used to remove duplicate lines from a file. It takes input from a file or from the output of another command through a pipe and prints the unique lines to standard output. The basic syntax of the uniq command is as follows: uniq [options] [input_file [output_file]] Here are some of the most commonly used options: -c: This option counts the number of occurrences of each line and displays it with the output. -d: This option only displays lines that are duplicated. -i: This option ignores case distinctions in both the input and the comparison of lines. -u: This option only displays lines that are unique (non-duplicated). If an input_file is specified, uniq reads the file and removes any consecutive duplicate lines. If an output_file is specified, uniq writes the output to that file instead of printing it to the standard output. Here's an example usage of the uniq command: $ cat example.txt apple banana banana cherry apple $ uniq example.txt apple banana cherry apple $ uniq -c example.txt 2 apple 2 banana 1 cherry In the above example, uniq removes the consecutive duplicate lines and prints the unique lines to the standard output. The -c option is used to count the number of occurrences of each line in the input file. If you want to see all the solutions for these challenges, you can find them on my Github repository: 🤍 Also, you can find me on my website: 🤍 where I write about different programming topics, and you can see my other projects.

Welcome to this in-depth series of videos where we will be providing solutions and explanations for various BASH challenges from Hackerrank. In this video, we will be tackling the "Remove the First Capital Letter from Each Element" challenge, which can be found at this link: 🤍 Our goal in this series is to document my thought process and solutions, and to focus on concepts and ideas rather than details. I will also be highlighting the differences between BASH and popular programming languages like Python and JavaScript. BASH is a powerful command-line interface for interacting with an operating system. It's a shell, and the most popular one. It can be used directly in the terminal or in scripts, which are text files containing a series of instructions. BASH is particularly useful for tasks such as text processing, file operations, connecting multiple programs, and system maintenance. It is also portable, working by default on many platforms. In bash, you can perform pattern matching using parameter expansions and the syntax ${array[🤍]/pattern/replacement}. This syntax allows you to search for a pattern in each element of an array and replace it with a specified replacement string. The pattern can contain wildcard characters, such as *, to match zero or more characters. For example, the pattern *[aA]* will match any string that contains either an 'a' or an 'A'. Here's an example of using pattern matching in an array in bash: # Define an array countries=(Argentina Australia Austria) # Use pattern matching to replace all occurrences of "A" or "a" with "X" echo "${countries[🤍]/[aA]/X}" This code will output: Xrgentina Xustrlia Xustria If you want to see all the solutions for these challenges, you can find them on my Github repository: 🤍 Also, you can find me on my website: 🤍 where I write about different programming topics, and you can see my other projects.

Welcome to this comprehensive series of videos where we will be giving solutions and explanations for various BASH challenges from Hackerrank. In this video, we will be addressing 7 tasks, including "Sort Command #1" (🤍 "Sort Command #2" (🤍 "Sort Command #3" (🤍 "Sort Command #4" (🤍 "Sort Command #5" (🤍 "Sort Command #6" (🤍 "Sort Command #7" (🤍 Our goal in this series is to document my thought process and solutions, and to focus on concepts and ideas rather than details. I will also be highlighting the differences between BASH and popular programming languages like Python and JavaScript. BASH is a powerful command-line interface for interacting with an operating system. It's a shell, and the most popular one. It can be used directly in the terminal or in scripts, which are text files containing a series of instructions. BASH is particularly useful for tasks such as text processing, file operations, connecting multiple programs, and system maintenance. It is also portable, working by default on many platforms. The sort command in Unix-like operating systems is used to sort the lines of a file or the output of a command in a specified order. By default, sort sorts the lines in ascending order and prints the result to the standard output. The basic syntax of the sort command is as follows: sort [options] [file] Here are some of the most commonly used options: -r: This option sorts the lines in descending order. -n: This option sorts the lines numerically. -f: This option ignores case distinctions. -u: This option removes duplicate lines. If a file is specified, sort reads the file and sorts its lines. If no file is specified, sort reads from standard input. Here's an example usage of the sort command: $ cat example.txt 4 2 3 1 $ sort example.txt 1 2 3 4 $ sort -r example.txt 4 3 2 1 $ sort -n example.txt 1 2 3 4 In the above example, sort sorts the lines of the input file example.txt in ascending order by default, but it also can sort in descending order using the -r option, sort numerically using the -n option, or ignore case distinctions using the -f option. If the input file contains duplicate lines, the -u option can be used to remove them from the output.
