#printA time-saving feature of context searches isthat the editor remembers the last regular expressionmentioned, and if you just say // or ??with no expression, it assumes the same one.  Thus /abc/s//def/searches for a line with 'abc', and, on finding it,changes the 'abc' to 'def'.    Similarly /qqq/s///finds a 'qqq' and then throws it away, as if thecommand were /qqq/s/qqq//In this directory is a file 'error' which contains"servixe" as a mistyping for "service".  Findthe bad instance and fix it, if possible with one command.Then rewrite the file and type 'ready'.#create RefThis file contains many copiesof the word servicebut in all of those lineswith service in themthe next line has aservice that is spelledwrong unlike the otherservices.#create errorThis file contains many copiesof the word servicebut in all of those lineswith service in themthe next line has aservixe that is spelledwrong unlike the otherservices.#user#cmp error Ref#log#next55.1a 1054.1b 8
