Print out file lines with special characters - Linux

I have a txt file with that is formatted like this:

xxxxxxxxx,xxx

with a few thousand lines. I have this command right now to delete the special characters from the file sed -i -e:a -e 's/[^0-9]\(.*,\)/\1/;ta' file.txt

instead of editing the actual file, is there a way to print out the line of text that each individual one lies on?

I only need to test the first 9 characters as every line has a comma in it. :)

It SOUNDS like all you want is:

grep '[^[:alnum:]]' file

but without sample input/output we're just guessing.
