Unix Tip #4057- March 21, 2012
APPENDING TEXT AT BOTH ENDS
If you need to append some
text to both the ends of a
string in vi, use the
following command in vi:
:/^\(.*\)/s//starttextcomeshere \1 endtextcomeshere/
If "iamworthless" is the text
at the position of the cursor
in the vi editor, the output
of the command:
:/^\(.*\)/s//DONTFEEL \1 ANYTIME/
DONTFEEL iamworthless ANYTIME
As you guessed, "DONTFEEL " and
" ANYTIME" are the strings you
would like to crush
"iamworthless" with. The "\1" is
the variable that stores the
entire pattern searched by
the "/\(.*\)/"
