Hi Petra,

try something like this.

# grep "17[5-6][0-9][0-9]" file

Robert-Jan,

The statement

grep "17[5-6][0-9][0-9]" file

will also include the numbers 17500-17584 and 17644-17699

thus they need to include grep -v 's

# grep "17[5-6][0-9][0-9]" file | grep -v -e "175[0-7][0-9]" -e "1758[0-4]" -e "1764[4-9]" -e "176[5-9][0-9]"

No gerexpr, but:

for i in `cat file`
do
if [ "$i" -gt 17584 ]
then
if [ "$i" -lt 17644 ]
then
echo $i
fi
fi
done

HTH,

Gideon

Thanks for the reply, but it's not exactly what I want. The problem is this I want to match just between 17585 to 17643 this gives a match on 17644 to 17699 as well.

Hi Petra,

Check Harry's second option, he allready added the grep -v options to remove the ranges.

Ps
Thanks Harry for the correction.

She asked "IN" a regex :)

# echo "17485" | perl -nle'/\b(17\d\d\d)\b(??{$x=$^N>=17585&&$^N<=17643?"":"(?<=X)"})\b/ and print "IN"'

# echo "17585" | perl -nle'/\b(17\d\d\d)\b(??{$x=$^N>=17585&&$^N<=17643?"":"(?<=X)"})\b/ and print "IN"'
IN

OK, that's dirty!

# echo "17585" | perl -nle'/\b17(5(8[5-9]|[6-9]\d)|6([0-3]\d|4[0-3]))\b/ and print "Match!"

Enjoy, Have FUN! H.Merijn
