A line, or dash (6)

I believe the answer is:

career

This clue is a double definition.

'a line' is the first definition.
(career is a kind of line)

'dash' is the second definition.
(thesaurus)

'or' is the link.

(Other definitions for career that I've seen before include "Rush madly" , "Quick" , "Life's work path" , "Life (in terms of work etc)" , "Run - profession" .)

I've seen this clue in the Evening Standard.
