Unix Tip #4485- June 22, 2014


SEARCH : Home : Help : Today's Tip

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 "/\(.*\)/"
