10.2 Pagers: +more, less, and most

+ +
+

10.2.1 more

+ +

more(1) is what we call a pager utility. Oftentimes the +output of a particular command is too big to fit on one screen. The individual commands +do not know how to fit their output to separate screens. They leave this job to the pager +utility.

+ +

The more command breaks the output into individual screens +and waits for you to press the space bar before continuing on to the next screen. +Pressing the enter key will advance the output one line. Here is a good example:

+ + + + + +
+
+% cd /usr/bin
+% ls -l
+
+
+ +

That should scroll for a while. To break up the output screen by screen, just pipe it +through more:

+ + + + + +
+
+% ls -l | more
+
+
+ +

That is the pipe character (shift backslash). The pipe is short for saying take the +output of ls and feed it into more. You +can pipe just about anything through the more command, not just +ls. Piping is also covered in Section 8.2.3.

+
+ +
+

10.2.2 less

+ +

The more command is quite handy, but often you will find that +you have advanced past the screen you wanted. more does not provide a way to go back. The +less(1) command provides this functionality. It is used in the +same way as the more command, so the previous examples apply +here too. So, less is more than more. +Joost Kremers puts it this way:

+ + +
+

less is more, but more more than more is, so more is less less, so use more less if you want less more.

+
+
+ +
+

10.2.3 most

+ +

Where more and less leave off, most(1) picks back up. If less is more than +more, most is more than less. Whereas the other pagers can only display one file at a time, +most is capable of viewing any number of files, as long as each +file's window is at least 2 lines long. most has a lot of +options, check the man page for full details.
