Description
*Monthly Update*Oct 2021 : Added/ Updated Grep and Egrep VideosApr 2021 : Updated AWK VideosJan 2021 : Added Questions & ExercisesAWK & SEDMany UNIX utilities generates rows and columns of information. AWK is an excellent tool for processing these rows and columns, and is easier to use AWK than most conventional programming languages. It can be considered to be a pseudo-C interpreter, as it understands the same arithmetic operators as C. AWK also has string manipulation functions, so it can search for particular strings and modify the output. AWK also has associative arrays, which are incredible useful, and is a feature most computing languages lack. Associative arrays can make a complex problem a trivial exercisesAWK Coverage Basic to Advance AWKEnvironment Setup with Test DataBasic Operations : Fetch One or Multiple Columns DataBasic Operations : Fetch One or Multiple Columns Data with SeparatorConditionally Fetch Data using Logical OR and Logical ANDCondition Handling with AWK CommandsAWK Looping AWK BlocksSave AWK Results to the fileSED CoverageSED IntroductionDisplay one or Few lines in OutputDisplay Data by Search conditionsSkip Data to display in outputFind and Replace DataSearch | Insert | Update and Delete DataSearch Data using GREP commandsSearch Data in one or Multiple FilesSearch Data in All filesSearch data with case or ignoring caseSearch data with surrounding wordsAdvance Search Conditioncut CommandsCut ColumnsCut Range of ColumnsCut by characters
