Continuing from previous lessons....

Replacement Commands:-

Sometimes it's need to replace a particular word with another text in a file.It can be made "globally" or "specifically",the respective terms are better understood in the following example:

Suppose there is a text:

[code]Hello guys,this is Saptarshi Nag

I want to say you "hello world"[/code]

Now one wants to replace "hello" with "hi" globally,that is it will be-

[code]Hi guys,this is Saptarshi Nag

I want to say you "hi world"[/code]

Again one wants to replace the only one "hello" with "hi" like this

[code]Hi guys,this is Saptarshi Nag

I want to say you "hello world"[/code]

Now both are possible through last line mode.

For global replacement type the following in last-line mode:

[code]%s/text/replacement/g[/code] [g stands for global]

So in the first example it will be:

[code]%s/hello/hi/g[/code]

But for specific replacement,we have to use the following:

[code]%s/text/replacement/gc[/code] [gc stands for global with confirmation]

Here for every replacement system wants to know if user wants to replace text or not.If yes,press 'y' else 'n'.

Therefore the second example can be done with:

[code]%s/hello/hi/gc[/code]

Now apply it yourself
