Pattern Replacement

Pattern replacement in shell scripting involves finding specific patterns within strings and substituting them with other strings. This is a fundamental text processing technique used to modify and transform data, allowing for tasks like cleaning up input, standardizing formats, or extracting relevant information. Shell tools like sed, parameter expansion, and awk are commonly used to achieve pattern replacement.
