I means walk the straight and narrow, don't screw up and get into trouble. He should have a steady job and take care of his family like a man is suppose to do.
Yes, "Walk the Line" is the title of the movie about Johnny Cash. It was also the title of one of his songs.

"What does the expression "walk the line" mean?"
In the case of the songs, the expression to "walk the line," means to be faithful and true to the person that you're supposed to be in love with. In the song "I Walked the Line," it was a pledge by Johnny Cash, to remain true , and be faithful, to his then wife Vivian.

That's a reference to the Johnny Cash song "I Walk The Line". It means to be faithful and be on guard to protect the relationship.
Johnny was in the US Air Force. In the USAF, planes are parked on the tarmac in a line (the flight line) and they are fueled and ready to go at a moment's notice. So, guards patrol the flight line to protect the planes against someone who would do harm to them. That guard duty is called "walking the line".
