That=20 could perhaps become a feature request for GNU grep: with -o and -n, also= =20 print the column number of the first character. That being said, if you truncate the N first characters of the matching=20 line, you have to parse the original line (that is, not the line that grep= =20 or another tool outputs) to find the matches anyway. --6ZRdvFg1td--
