As noted by others, grep is not the best tool to use in this context. But, if you absolutely must...

grep -E '^((1[1-9])|([2-9][0-9]))$'

Off the top of my head:

grep "^..$" query.txt | grep -v 10

Note that this only works because your range happens to coincide with 'all two digit numbers except 10'.

This might work for you, as long as your requirement is actually 10 <= x < 100, as it would include 10:

grep ^..$ query.txt

grep is the wrong tool to use.

try this one-liner:

awk '($0+0)>10 && ($0+0)<100' file
