Searching through lines without lower case

I'm looking to search through a line where I must indicate the 3rd and 4th characters should not be lowercase. This is what I have so far however, I'm not sure how to indicate both characters in one line of code.

    ls grep | $...[!a-z].$....[!a-z]

Try this. I did the following and it worked for me.

ls | grep -e '^..[^a-z][^a-z].*$'

Example:

mkdir abcD abcd abcde abCD ABCD ABcd abCDe
ls | grep -e '^..[^a-z][^a-z].*$'

When I executed the above commands, I go the following output:

$ ls | grep -e '^..[^a-z][^a-z].*$'
ABCD
abCD
abCDe
$

You are trying to restrict lower case using [!a-z]. You should use [^a-z] for this purpose.

Hope this helps.
