grep command

[iranzo]

Thanks to all
OK, "grep -x" works !
but the reel file is :
156.152.45.5 toto
156.152.45.58 titi
156.152.45.589 bubu
And that i want is only the field "toto"
of the file when $ADRESSIP=156.152.45.5

why don't you ,....

grep "156.152.45.5 toto" file

Because, I don' know that the text is 'toto'.
This is en example.
I search a comment by the variable $ADRESSIP.

This is not so easy...

Hi Iranzo,
if the name "toto" or whatever is the second field, you can do:

awk '/'$ADRESSIP' / {print $2}' file

This prints only the second field if the first one matches $ADRESSIP. Be carefully with the space after '/'$ADRESSIP' /
^ this one

Hope this helps.

Frank.

Hi,

Sorry but the space is not clear enought in the previus message,

awk '/'$ADRESSIP'/ {print $2}' file

I think this is "more" clear.

I think this is not possible with grep/egrep/fgrep. May be gnu grep will help.

Without gnu grep, you can do it as follows.

grep "156.152.45.5" ./file|awk -F " " '{if(length($1)==12)print}'

similar to Mr. Soler's

awk -v var=$ADRESSIP '
$1 == var {print $2;}' yourFile

Hai,

We can use ^ and $ to notify the begin and end of string. It is easy to get the exact string.

ADRESSIP=156.152.45.5
grep ^${ADRESSIP}$
