The --width
/-w
flag adjusts the width of the register command's output. Eg:
-w 100
With multiple comma-separated widths, it sets individual field widths:
-w 10,20,30,10,10
A width of "auto" means be as wide as necessary to avoid clipping any fields, up to the current terminal width if that can be detected:
-w auto
Individual fields can also have auto width. The exact semantics of this are TBD:
-w 10,20,auto,auto,auto
