next word of a particular word in linux


Hi all,

In linux is there a way to find the next word of a particular word of a file.

grep displays entire line of the particular word.

But i want only the exact next word of that particular word.is there any command for that.


Thanks in advance,
Dinesh.

Not exactly sure what you mean. It is often best to give an example. As far as grep goes, have a look at the -o option will give you only the text you are looking for and
maybe the -m option which allows you to stop after a particular number of matches.

I am not sure I understand your question. If you know the next word of a particular word is going to be that word, whats the point?

Do you want to know how many times a particular word appears in a text file?
Do you want to know on which line is the next appearance of a particular word?

In my mind there would be know reason for a command that just returns a word that you already know.

For example.. Let stay I have a text file containing all the text above this line.

grep word file.txt
The above command would return all the lines containing the word, therefore giving you some context as to how the word was being used, or where it was in the file.

A word search as your asking can be done in editors like vi and nano. In vi you can use the following command (while in command mode) to find the next "word".


/word

I think that what the OP wants is for a file that contains this line:

Code:
stuff stuff theword next more stuff
searching for the word "theword" will return "next".

Hi all,

for example i am having

Name Indians are great

in a file. if i use "grep Name <filename>" then the output would be "Name Indians are great"


But i want only "Indians" to be displayed if i use "grep Name <filename>"

i.e. the next word to "Name".

I think you can use awk for this, For example:

Code:
echo Name Indians are great | awk '{for(i = 1; i<=NF; i++) if($i=="Name") print $(i+1);}'
prints Indians

So you Can pipe the output of grep to it.

Hi Ashkan,

Thanks it works,

But i want some thing like awk '{for(i =0; i<NF; i++) if($i=="Name") print $(i+1);}' <filename>

then it should print indians.

This text "Name Indians are great" would be inside a file.

Could it be a little different?

grep the text in the file the pipe its output to awk, like this:
Code:
grep "Name" <filename> | awk '{for(i = 1; i<=NF; i++) if($i=="Name") print $(i+1);}'
it should work.

P.S.
I edited the first code a little it was wrong, (for(i =0; i<NF; i++) must be for(i = 1; i<=NF; i++))

You're Welcome

And it must be
Quote:
grep "Name" <filename>
not
Quote:
grep "Name Indians are great" <filename>
I'll edit it.

Why so complicated:
Code:
awk '/Name/{getline;print;exit}' RS=" " <filename>
If there are more possible versions of Name in the file that you want as well, simply remove the exit

A sed alternative:
Code:
sed -nr "s/.*Name (\w+) *.*/\1/p" file
