Remove lines containing a number less than/greater than a limit?

Question

I have a lot of lines like this, produced by grep -n:

path/to/dir/file1.txt:4: Match
path/to/dir/file1.txt:40: Another Match
path/to/dir/file2.txt:2: Match
path/to/dir/file2.txt:564: Yet another Match

I'd like to eliminate lines where the line number is less than (say) 10. I know I can get the line number easily with cut -d: -f2, but how could you then use this to discard the lines and continue piping the rest of the output in full so you end up with:

path/to/dir/file1.txt:40: Another Match
path/to/dir/file2.txt:564: Yet another Match

Answer 1

You can do:

your command | awk -F: '$2>=10'
