text transformation

In the world of Unix-like operating systems, several tools make text processing a breeze, and one of the most potent among them is sed, short for Stream Editor. It provides a way to perform text transformations on input stream (a file or input from a pipeline), making it an invaluable tool for scripting and data processing. If you're interested in learning how to install and use sed to simplify your command-line text processing tasks, you've come to the right place! Sed is a non-interactive stream editor that performs basic text transformations on an input stream (a file or input from a pipeline). While it’s mostly used for substituting text, its capabilities extend to more complex pattern matching and manipulation tasks.

In the world of UNIX and Linux, simple commands are the strongholds that make complex tasks feasible. One such command that often flies under the radar but is incredibly powerful in text processing is the tr command. Short for "translate", tr is used for transforming and deleting characters from input text. It reads bytes from the standard input, processes them to make required substitutions, and writes the result to standard output. This might not sound glamorous at a first glance, but its utility in scripting and text manipulation is unmeasurable. The syntax of tr is straightforward : tr [OPTION] SET1 [SET2] Here, SET1 is the set of characters to be replaced or removed, and SET2 is the set of characters to replace with.
