Below is a command<br />
&nbsp; &nbsp; sort -t: +2n myfile<br />
I know it will sort the 3rd field numerically<br />

Now I have this<br />
&nbsp; &nbsp; sort -t: +2n -3 myfile<br />
I see this in my textbook but then what is the use? I don't understand :(

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
