-n: Suppresses the default behavior of sed, which is to print all lines to standard output.‘sed’ has several flags and arguments that can be used to control its behavior: Here’s an example that replaces all occurrences of the word “apple” with the word “banana” in a file named fruits.txt: Example of Sed Command Replacing Occurrences of a Particular Word The command part is used to differentiate between the various actions, such as insert, delete, and substitute. An address can be a line number, a string literal, or even a regular expression. The address specifies the location where the change is to be made. The sed command has two parts: an address and a command. To make changes to the original file (not recommended) “-i” flag can be used.
The redirection operator (>) has to be used to redirect the output to a file.

One important thing to note while working with sed is that the original input file is unchanged, and the results are sent to standard output. If no input file is specified, sed will process input from standard input.
inputfile(s): The name of the input file(s) to be processed by sed. This can be a simple search and replace operation or a more complex transformation using regular expressions. command or script: The text processing command to be executed by sed. Some standard options include -n suppressing the default printing of all lines, -i to edit files in place, and -e specifying multiple commands. options: optional flags that control the behavior of sed. Some common examples of stream data in Linux include: In Linux, stream data refers to a continuous flow of text-based data that can be processed in real-time. Here Are Some Common Examples of Stream Data in Linux Because of this, it is now feasible to carry out complicated transformations on extremely huge files without running out of memory. This allows the data to be processed more quickly. Stream editing is a handy technique when dealing with enormous volumes of data since it may process the data one line at a time rather than putting the full file into memory. Because data is processed continuously with sed, it is possible for it to be much quicker and more efficient than other text editors, which load the entirety of the file into memory before making any modifications. It reads text data from an input source (such as a file or standard input), edits the text according to a set of editing commands, and then sends the edited text to an output destination (such as standard output or a file).
