Although decades old, vi is still a powerful editor although the kinds of task you describe are usually done with sed.

Well, in VI I just hit "/WORD" or toss in some spaces/whitespace regexpr. Now hit 'dd'.

But I suspect you want more? Like all lines in the file that match? Or like put the whole think in a script?

I would suggest the sed editor for that job instead of vi. Is is more script oriented imho.

But why not simply use:
$ grep -v WORD file-with-word > file-without-word.

Again, add -E or wordboundaies as needed

If GREP can not do the job, then please explain why not. Know that, someone may be able to resolve it, or may be able to come up with a better vi or sed solution based on a refined problem description.

fwiw,
Hein.

Of course, the standard first-line-of-defense cam always be found in the manpages:

Hi,

For searching a word in vi, Go to command mode
/word
Curser will on the word. You can delete the entire line by 'dd'(without quote)

Hello,

As always, take a look at "man vi" for complete listing of commands and this link should be helpful...

I am mystified as to why you (and some other individuals) post the same answers hours or days after other participants. I am mystified why your posts are divided into multiple ones usually minutes apart.

Please read what has alraedy been written in a post and think a little before you write. We need fresh information, not a "me too".

Hi James,

I am mystified as to why you (and some other individuals) post the same answers hours or days after other participants. I am mystified why your posts are divided into multiple ones usually minutes apart.

*** My long posts are not getting into forums.. Thats why i prefer short answers. When i post long answers, i always get Error posting message. May be i need to change my browser from Firefox.. Even, Muthukumar has this problem from his machine.

Please read what has alraedy been written in a post and think a little before you write. We need fresh information, not a "me too".

***I gave a fresh information that defers from what others gave (I used "dd" to delete where your was "dw").

Thanks,
Arun

Ditto.
It ads no value and it distracts.
Myself, and other also I suspect, keep following topics where we opted to reply. So when a good time later a redundant reply is added then not only that reply time is wasted, but my time is also wasted.
I have the same problem with replies only suggesting to add points.
I know, it is entirely my own choice to re-visit, but still...

>>> *** My long posts are not getting into forums..

I beg to differ. You may well be correct, but I suspect it was just the general reply trouble we all went through a while ago. Just wait and the replies would be there, and keep a backup copy handy just in case.

>> change my browser from Firefox..

I tend to use firefox. No problem for me.

>> ***I gave a fresh information that defers from what others gave (I used "dd" to delete where your was "dw").

fwiw: My reply mentioned dd hours earlier.

'nuff said.

I am looking forward to many more great replies from all, just less noise if you could please!

Kindest regards,
Hein.

lots of good references to tutorials, etc above. To answer your question, from the command mode of vi, type ":g/WORD/d"

The : puts you in ed mode,
g/WORD/d
means: globally, search for WORD, and delete the line(s) it is found on
hit the enter key.
