Grep a line with between 3 and 5 digits

ceemh3 · #1 (**permalink**) 09-17-2007

Hi,

I am having problems using grep to extract only 3,4 or 5 digit numbers from a text file, using:

grep '\<[0-9]\{3,5\}\>' test.txt
or
grep '[0-9]\{3,5\}' test.txt
or
egrep '[0-9]{3,5}' test.txt

I would appreciate any help that anyone can give me

thanks

On Linux, this command works correctly:

Code:

grep '\<[0-9]\{3,5\}\>' test.txt

On Solaris you may try this (not tested though):

Code:

/usr/xpg4/bin/grep -E '\<[0-9]\{3,5\}\>' test.txt
