grep exact pattern

kapila · 07-31-2009, 01:02 AM

Hello,

Need to find a particular pattern from a file-

$grep -w "titan/WEB-INF/resources/mmt_engine.properties" a
titan/WEB-INF/resources/mmt_engine.properties.b2c.prod 1.2.2.1
titan/WEB-INF/resources/mmt_engine.properties 1.2.2.1
titan/WEB-INF/resources/mmt_engine.properties.b2c.prod 1.2.2.2

where i need only result as-
titan/WEB-INF/resources/mmt_engine.properties 1.2.2.1

how can i do this?

regards
Kapila

You can do,

Code:

grep -w  "titan/WEB-INF/resources/mmt_engine.properties " a

Mind that extra space after properties.

Hope this helps

grep 'titan/WEB-INF/resources/mmt_engine.properties 1.2.2.1' somefile

note single quotes, not backquotes

Thanks all for your replies.
But have tried with -w & -x option keeping pattern in quotes. its gives same thing.
My command knows pattern in which version 1.2.1.2 is not known.

What if you add a trailing space in the pattern, as suggested by Vikas above?

kapila · 07-31-2009, 09:09 AM

I have tried command like
grep -w "pattern " file

but this also fails then

colucix · 07-31-2009, 09:20 AM

At this point is not clear what is the result you expect. Please, can you post the input file (or a relevant part of it) and the desired result? Use CODE tags to preserve the original formatting of the file (spacing, indentation and so on). Thanks.

Like colucix said, more information would be nice.
Without knowing the layout of the file you are trying to get this data from, you could use awk to do:

Code:

awk '$1 ~ /titan\/WEB-INF\/resources\/mmt_engine.properties/ && $1 !~ /.b2c.prod/ && $2 ~ /1.2.2.1/' file

when i do --

>>grep "titan/WEB-INF/resources/mmt_engine.properties" a
get o/p as -->

titan/WEB-INF/resources/mmt_engine.properties.b2c.prod 1.2.2.1
titan/WEB-INF/resources/mmt_engine.properties 1.2.2.1
titan/WEB-INF/resources/mmt_engine.properties.b2c.prod 1.2.2.2

I want output as -
titan/WEB-INF/resources/mmt_engine.properties 1.2.2.1

So constant pattern known is – “titan/WEB-INF/resources/mmt_engine.properties” not version !!

So I should be able to do something like-
>>grep "titan/WEB-INF/resources/mmt_engine.properties" a--- how????
o/p
titan/WEB-INF/resources/mmt_engine.properties 1.2.2.1

any help?

Please refer to my earlier post. This can not fail.

Code:

grep -w  "titan/WEB-INF/resources/mmt_engine.properties " a

There is an extra space after properties, how could you get same result ? It CAN NOT search character after properties (.b2c.prod) in your case.

Please find my logs.

Code:

-sh-3.00$ cat a
titan/WEB-INF/resources/mmt_engine.properties.b2c.prod  1.2.2.1
titan/WEB-INF/resources/mmt_engine.properties   1.2.2.1
titan/WEB-INF/resources/mmt_engine.properties.b2c.prod  1.2.2.2
-sh-3.00$
-sh-3.00$ grep -w "titan/WEB-INF/resources/mmt_engine.properties " a
titan/WEB-INF/resources/mmt_engine.properties   1.2.2.1

svn CCR-Tag # grep -w "titan/WEB-INF/resources/mmt_engine.properties " a
svn CCR-Tag #..

I tried teh same with extra space. Its giving nothing

Wim Sturkenboom · 08-06-2009, 02:58 AM

Are you sure it's a space between properties and version, not a tab character or other whitespace?

You can try

Code:

wim@btd-techweb01:~/test/lq744068$ grep  "titan/WEB-INF/resources/mmt_engine.properties[[:space:]]" a
titan/WEB-INF/resources/mmt_engine.properties   1.2.2.1
titan/WEB-INF/resources/mmt_engine.properties   1.2.2.x

The latter one contains a tab character
