how do I identify files with characters beyond a certain range.

I have a directory with hundreds of files that can not have data pass column 80. I do not know of way to combine "grep" and "cut" command.

I tried:
cat * | cut -c 81-120 |pg
but it only shows me the line, not the file name.

Any help would be appreciated. Been on this all day.

grep -l "^.\{81\}$" *

81 is used because you are serching for files which contain at least 1 line with 81 or more characters.

I think I was over engineering it all day today. Thanks. I'd buy you a beer if I could.

I prefer vodka.
