14<title>/etc/issue (Customizing your logon)</title>
16<para>When you first boot up your new <acronym>LFS</acronym> system, the logon
17screen will
18be nice and plain (as it should be in a bare-bones system). Many people
19however, will want their system to display some information in the logon
20message. This can be accomplished using the
21file <filename>/etc/issue</filename>.</para>
23<para>The <filename>/etc/issue</filename> file is a plain text file
24which will also accept certain Escape sequences (see below) in order to
25insert information about the system. There is also the file
26<filename></filename> which can be used when logging on remotely.
27<command>ssh</command> however, will only use it if you set the option in the
28configuration file and will also <emphasis>not</emphasis> interpret the
29escape sequences shown below.</para>
31<para>One of the most common things which people want to do is to clear
32the screen at each logon. The easiest way of doing that is to put a
33"clear" escape-sequence into <filename>/etc/issue</filename>. A simple way of doing
34this is to do <userinput><command>clear &gt; /etc/issue</command></userinput>.
35This will insert the relevant escape code into the start of the
36<filename>/etc/issue</filename> file. Note that if you do this, when
37you edit the file, you should leave the ^[c character on
38the first line alone.</para>
40<para>The following escapes are recognized by agetty (the program which
41usually parses <filename>/etc/issue</filename>). This information is from
42<command>man agetty</command> where you can find extra information
43about the logon process.</para>
45<para>The <filename>issue</filename> file can contain certain escape codes to
46display various information. All escape codes consist of a backslash
47(\) immediately followed by one of the letters explained
48below (so <option>\d</option> in <filename>/etc/issue</filename> would
49insert the current date).</para>
51<screen>b Insert the baudrate of the current line.
52d Insert the current date.
53s Insert the system name, the name of the operating system.
54l Insert the name of the current tty line.
55m Insert the architecture identifier of the machine, e.g., i486
56n Insert the nodename of the machine, also known as the hostname.
57o Insert the domainname of the machine.
58r Insert the release number of the kernel, e.g., 2.4.16.
59t Insert the current time.
60u Insert the number of current users logged in.
61U Insert the string "1 user" or "&lt;n&gt; users" where &lt;n&gt; is the
62 number of current users logged in.
63v Insert the version of the <acronym>OS</acronym>, e.g., the build-date etc.</screen>
