Hello Guys , This video is about understanding advanced text processing using awk command in linux . awk , being a scripting language for text processing provides various features to process text as per requirement. It also provides various programming features like variables, if else , loops , functions etc that can be used to process text . I had started with explaining the basics of awk command with examples . I had explained pattern and actions of awk command which are two major parts of awk command. I elaborated using pattern matching , regex match , relational expressions pattern , comparison operators , logical OR and logical AND operator , providing range in awk and some special expression patters like BEGIN and END . Some Built in variable like OFS, FS , NR , NF , FILENAME , RS and ORS is also discussed with examples. At the end , I had explained how programming features can be used with awk command.
