Each line read starts a cycle. To the pattern space, sed applies one or more operations which have been specified via a sed script. sed implements a programming language with about 25 commands that specify the operations on the text. For each input line, after running the script, sed ordinarily outputs the pattern space (the line as modified by the script) and begins the cycle again with the next line. Other end-of-script behaviors are available through sed options and script commands, e.g. d to delete the pattern space, q to quit, N to add the next line to the pattern space immediately, and so on. Thus a sed script corresponds to the body of a loop that iterates through the lines of a stream, where the loop itself and the loop variable (the current line number) are implicit and maintained by sed. linux,sed,sed command,linux tutorial,linux for beginners,linux sed command tutorial,command line,substitute,regular expression,linux basic commands,linux sed command,learn linux sed command,sed tutorial,sed examples,sed linux,sed command tutorial,sed command linux,sed search and replace,linux sed,linux tutorial for beginners,shell script,sed command in linux,linux text processing,linux filtering,linux tutorial 2021,linux tutorial sed,text edit sed sed command in hindi
