# s is substitute command # / is a delimiter # REGEXP is regular expression to match # REPLACEMENT is a value to replace
FLAGS can be any of the following # g Replace all the instance of REGEXP with REPLACEMENT # n Could be any number,replace nth instance of the REGEXP with REPLACEMENT. # p If substitution was made, then prints the new pattern space. # i match REGEXP in a case-insensitive manner. # w file If substitution was made, write out the result to the given file. # We can use different delimiters ( one of @ % ; : ) instead of /
