While gzip itself works on single files, it is commonly used in conjunction with tar to handle multiple files and directories, providing a versatile solution.
In Bash, exit codes (also known as return codes or status codes) are numeric values returned by executed commands or scripts to indicate the result of their execution.
It allows you to test a variable or an expression against a set of patterns and execute a block of code corresponding to the first matching pattern.
In Bash, the printf command is used to format and print text to the terminal. It works similarly to the printf function in other programming languages.
A special line that tells the operating system which interpreter to use to execute the rest of the script, also used in other scripting languages, such as Python, Perl, and Ruby.
Similar to functions in other programming languages, a Bash function takes input arguments, processes them, and may produce output results.
String comparisons in Bash are essential for various scripting scenarios including validating user input, checking for specific patterns, or sorting data.
While loops are commonly used to process files, read input, validate data, or perform any task that requires iterative execution until a specific condition is met.
The most common approach is to use the IFS variable to specify the delimiter character and then use read or parameter expansion to split the string.
With the for loop, Bash scripts can efficiently iterate over lists, arrays, file contents, or numerical ranges, making it a powerful tool for automation and repetitive tasks.
