less: how to scroll horizontally by a screenful [closed]

Question

Using the unix command line tool less, how do I scroll horizontally? I need to scroll one (or a half) screen to the right or left

Escaut

Try less -S for horizontal scrolling and scroll horizontally with the arrow keys. – Clouse

No need for option -S Horizontal scroll works (using cygwin) even without it – Escaut

-S causes lines longer than the screen width to be chopped rather than folded. The default is to fold long lines; that is, display the remainder on the next line. Default could be chopped in your system, though. – Clouse

For horizontal scrolling , left arrow/right arrow would work (considering I understood your question) or do you wish to enable line wrap? – Strickland

No, the default is "Fold long lines" and not chopped - found this default value by using _S on less's "command prompt" – Escaut

You can use less -SEX (S for scrolling horizontaly, E to quit on the first EOF & X to disable first clear) – Firenew
