Manuel,

James F.'s method should work.

Hi (again) Manuel:

This is clearer:

# grep mmarano filename| grep -v smmarano|grep -v mmarano1

That is, is your file. No assumptions are made as to where one any line(s) the tokens appear.

The 'grep -x mmarano' form suggested above and the regular expression ^mmarano$ accomplish the same thing -- they assume that the entire input line matches the string or regular expression.

Regards!

Hi Manuel,

# grep mmarano file
ore
# cat file | grep mmarano

1. Look at if the different regex exploitation of egrep can help
2. use word bounds in regex engines that support it (why do I always think in perlish styles ? :)

# perl -ne'/\bmmarano\b/ or print' datafile

Give this a try

cat | grep '^mmarino$'

Manuel,

Try grep -x mmarano.

funny - when I try the same thing it works perfectly for me

[John Meissner]

Oh I see - are you just typing grep "^mmarano$"...
no i was typing cat file | grep "^mmarano$"
that works for me.

[Pete Randall]

John,

Me, too.

Hi:

Here's one simple way"

# cat /tmp/grep|grep mmarano|grep -v smmarano|grep -v mmarano1

The easiest way (of course) is to use GNU grep with the -w option:

-w, --word-regexp force PATTERN to match only whole words

# grep -w mmarano infile

[harry d brown jr]

grep -e "^mmarano$" -e " mmarano$" -e "^mmarano " -e " mmarano "

Hi,

Use -x (eXact) option, this Matches are recognized only when the entire input line matches the fixed string or regular expression.

grep -x mmarano file

Of course, to do this between "mmarano" must exist al least blank spaces that limit the name like a one word.

I've tried with "grep ^mmarano file" and works fine!

If you have an inmediate charater delimiting mmarano name, you will use it into the match string, i.e. if you have a ":" character after "mmarano" string, you can specify exactly by: "grep mmarano: file"

Rgds.
