Keep ls Output from Scrolling

Q: When ls Output Scrolls Off the Screen

Whenever I type ls I can barely see the output of the directory because it scrolls by too quickly. How can I actually read the output?

A: "Piping" the Output of ls

You can prevent the output of ls from scrolling by too quickly by piping the output to a pager, such as less or more . The results are akin to the DOS command dir somedirectory /p , because you'll see the output one screen, or "page" at at time.

To read the output of /etc with less , for example, at the shell prompt, type:



ls -al /etc | less

To move forward a screen, press Space ; to move back a screen, press the B key; to quit, press Q .

You can achieve the same results with more , another pager.

Printing Output of ls

You can also print the directory by piping the output to a printer in the same way that you piped the output to your screen. Assuming you've configured a printer, to pipe the output type:



ls -al /etc | lpr
