The ‘awk’ command is a versatile Unix utility used for processing and manipulating text files or input streams. It is particularly useful for parsing structured data and extracting specific fields or patterns from text. The awk command processes input line by line and applies user-defined patterns and actions to each line. In short, awk stands for “Aho, Weinberger, and Kernighan”, the names of its creators. It is commonly used in command-line and scripting environments for data processing and text manipulation tasks.
