So for example, I have this text file:

use

user_99

12345

+10k lines...

And I want to remove those that have less than 4 characters from the command line,
I've already searched in google but no results came.

Any ideas? : )

I'd also like to remove lines with more than 3 numbers in the beginning.

sed or awk are good choices:

sed -rn '/^.{0,3}$/n; /^[0-9]{3,}/n; p' file



awk --re-interval 'length > 3 && !/^[0-9]{3,}/' file
