Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "For Linux users, ssh root@192.168.7.2 will log you in to the board."

A block of code is set as follows:

$ ifconfig -a
….
eth1      Link encap:Ethernet  HWaddr 1c:ba:8c:95:18:a0  
          inet addr:192.168.7.1  Bcast:192.168.7.3 Mask:255.255.255.252
          inet6 addr: fe80::1eba:8cff:fe95:18a0/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:21 errors:0 dropped:0 overruns:0 frame:0
          TX packets:101 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:5280 (5.2 KB)  TX bytes:21808 (21.8 KB)
….

Any command-line input or output is written as follows:

$ mount | grep sdb
/dev/sdb1 on /media/HYBOOT type vfat (rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks)
$ sudo umount /dev/sdb1
