AWK syntax and structure

AWK programs consist of a series of rules, where each rule specifies a pattern to match and an action to perform. The basic syntax of an AWK rule is as follows: pattern { action } The `pattern` specifies a regular expression or condition to match against each line of input, and the `action` specifies one … Read more

History of AWK

AWK was created in the late 1970s by Alfred Aho, Peter Weinberger, and Brian Kernighan at Bell Labs, as a tool for processing text files. Prior to AWK, text processing was typically done using general-purpose programming languages like C or Fortran, which required a lot of boilerplate code to handle common tasks like parsing and … Read more
