HI, Thanks for the reply.

I have a question for Sashi, I did want to use VI to do it..

But I don't know how to use VI to specify a range..

If you could tell me the detail , I would be appreciated.

Thanks

Using VI you can specify a range of lines to modify for the editing
command that you use such that your changes are only updated to the
paragraph you're interested in.

HI,

I want to do some global change in one paragraph of my file. 

Define "global change".
Define "paragraph".

Provide sample data.


Is there any way to do that?

Thanks.





I know the following block delimiters for the : commands

.. (dot) the current line
1 the first line
n the nth line
$ the last line
$-1 the second last line
'a the mark a
'n the mark n
'n+1 the line after mark n

Now go to the beginning of your block, do

ma

and you have set the mark a.
Then go to the end of your block, and do the substitute command
between the mark a and the current line

:'a,. s/oldstring/newstring/g

/g (global) means multiple matches within a line are all substituted.

The command
:u
undoes your change.
