iranzo — Thu, 10 Jun 2004 02:49:19 GMT

Hello,
here my file: 156.152.45.5
156.152.45.58
156.152.45.589
and variable $ADRESSIP=156.152.45.5
i want to do a "grep" $ADRESSIP on my file
with only $ADRESSIP in the output and not
other word (not 156.152.45.58,156.152.45.589)
Thanks a lot.

Hi,

You can do:

grep -w '$ADRESSIP' file

manish.

Try

grep "$ADRESSIP$" file

Note the $ at the end of the ADDRESSIP. This means that you will get any line that contains your IP address, followed by an end of line marker. This should exclude the other addresses from your search.

If that doesn't work, it may be that you have a space or tab character following the IP address. In this case, use

grep "$ADRESSIP " file
or
grep "$ADRESSIP" file

(use the TAB key rather than typing

Did you try:
grep -x $ADRESSIP file?
Using -x (eXact) Matches are recognized only when the entire input line matches the fixed string or regular expression.

Hi,

It works for me:

$cat file
debug
debug1
$DF=debug
$grep -w $DF file
debug

As you can see debug1 is not displayed. It displays only the word which we are looking for.

Check with egrep

$egrep -w $ADRESSIP file_name
$egrep -x $ADRESSIP file_name

Hi,

If you only need $ADRESSIP in the output, you can do a grep and if grep is successful then print the ip, for example:

ADRESSIP=156.152.45.5
grep $ADRESSIP file && echo $ADRESSIP

if no $ADRESSIP in file the command line output nothing, if $ADRESSIP in file the command line outputs the $ADRESSIP only

Hi again,

I made a mistake in the command, the correct one is:

grep $ADRESSIP file > /dev/null && echo $ADRESSIP.

Sorry
Frank.

Frank,
What about this one:

# cat > xyz
one
two three
four
five
#
# VAR=one
# cat xyz | grep "$VAR"
one
#

Remember i am using default POSIX shell of HPUX.
This should work with KSH also.

Regards,

IN RESPONSE TO YOUR: on my HPUX B.11.00 "grep -x and grep -w" not working ! Problem with patches ?

YES, you need to PATCH your system, as "grep -w" and "grep -x" should exist and work.

Sorry,
Earlier one is having bug in that. Try this one. it is bit lengthy, hope you don't mind.

create one script called "myscr" and you have file called "xyz" then:
# cat myscript

#!/usr/bin/ksh
list=`cat xyz`
myfunct()
{
VAR11=$#
while true
do
if [ VAR11 -gt 0 ]
then
echo $1
shift
let VAR11=$VAR11-1
else
exit
fi
done
}
myfunct $list

----- end of script ----------

#chmod +x myscript
#./myscript | grep "$VAR"

I have tested this one and works fine.

Regards,

Bharat Katkar — Thu, 10 Jun 2004 06:57:35 GMT

Now look at this one, more user friendly.
Again don't mind the lenght, it's once for all.

#!/usr/bin/ksh
echo " Enter values to be searched in file : "
read VAR1
echo "\n Enter file name in which the above value to be searched : "
read VAR2
list=`cat $VAR2`
myfunct()
{
VAR11=$#
while true
do
if [ VAR11 -gt 0 ]
then
echo $1
shift
let VAR11=$VAR11-1
else
exit
fi
done
}
myfunct $list | grep "$VAR1"

Let me know if that helped.
Regards,

Hey,

I get this problem when I use -w. Can u download a gnu version of grep and try grep -w ?.

I think HP-UX grep don't have the -w option. Someone mentioned about a patch ??

We resolved this be downloading the gnu grep (ggrep) from www.gnu.org. ggrep has much more than -w to offer in my opinion.

Mark Grant — Thu, 10 Jun 2004 07:15:51 GMT

Does this work

perl -ne '/\b156.152.45.5\b/ && print' datafile

Re: grep command

Mark Grant — Thu, 10 Jun 2004 07:20:26 GMT

Or, if you want it to take the variable

export ADRESSIP="156.152.45.5"
perl -ne '/\b$ENV{ADRESSIP}\b/ && print'

Re: grep command

KapilRaj — Thu, 10 Jun 2004 07:31:31 GMT

i can confirm "-w" doesn't work in AIX as well
