grep command

[iranzo]

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,

# grep '$ADRESSIP' file

Hi,

You can do:

grep -w '$ADRESSIP' file

manish.

[Chris Wilshaw]

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.

manish

on my HPUX B.11.00
"grep -x and grep -w" not working !
Problem with patches ?

[Sanjay Kumar Suri]

Check with egrep

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

Hi,

If you don't hate awk 8))):

awk `$1==A {print }' A=$ADDRESSIP $FILE

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
