The Linux Cat command numbers lines

$cat-b/etc/X11/XF86Config... 14#MultipleFontPathentriesareallowed (theyareconcatenatedtogether) 15 percent BydefaultMagazine Red Hat 6.0 and now available server dependents of 16#theXservertorenderfonts. 17FontPath "/ usr/X11R6/lib/X11/fonts/TrueType" 18FontPath "unix/:7100" 19EndSection... $cat-n/etc/X11/XF86Config... 20#MultipleFontPathentriesareallowed (theyareconcatenatedtogether) 21 percent BydefaultRedHat 6.0 and existing existing server dependents of 22#theXservertorenderfonts. 23 24FontPath "/ usr/X11R6/lib/X11/fonts/TrueType" 25FontPath "unix/:7100" 26 27EndSection.

The Linux Cat command can also be helpful when you view files that contain non-print characters such as tabs. You can display tabs with the following options:

-T displays tabs as ^ I

-v displays non-printed characters, except for line breaks and tabs, which use "control sequences" that are equivalent to each other. For example, when you work with a file generated on a Windows system, the file will use Control-M (^ M) to mark the end of the line. Characters with codes greater than 127will be preceded by M-(for "meta"), which is equivalent to adding Alt- before characters in other systems.

-E adds a dollar sign ($) at the end of each line.
