Adding characters at the start and end of each line in a file

April 30, 2023 by Tarik

In vim, you can do

:%s/^\(.*\)$/"\1"/

s/regex/replace/ is vim command for search n replace.
% makes it apply throughout the file
^ and $ denotes start and end of the line respectively.
(.*) captures everything in between. ( and ) needs to be escaped in vim regexes.
\1 puts the captured content between two quotes.
