<title>Introduction to <application>Ed</application></title>
<para><application>Ed</application> is a line-oriented text editor. It
is used to create, display, modify and otherwise manipulate text files,
both interactively and via shell scripts. Ed isn't something which many
people use. It's described here because it can be used by the patch
program if you encounter an ed-based patch file. This happens rarely
because diff-based patches are preferred these days.</para>

<title>Installation of <application>Ed</application></title>
<para><application>Ed</application> normally uses the
<emphasis>mktemp</emphasis> function to create temporary files in
<filename class="directory">/tmp</filename>, but this function contains
a vulnerability (see the section on Temporary Files at
<ulink url="http://en.tldp.org/HOWTO/Secure-Programs-HOWTO/avoid-race.html"/>).
Apply the following patch to make <application>Ed</application> use
<emphasis>mkstemp</emphasis> instead, a secure way to create temporary
files:</para>
<screen><userinput><command>patch -Np1 -i ../ed-&ed-version;-mkstemp-1.patch</command></userinput></screen>
<para>Install <application>Ed</application> by running the following
commands:</para>
<screen><userinput><command>./configure --prefix=/usr --exec-prefix="" &amp;&amp;
make</command></userinput></screen>
<para>Now, as the root user:</para>
<screen><userinput role='root'><command>make install</command></userinput></screen>
</sect2>
<sect2>
<title>Command explanations</title>
<para><parameter>--exec-prefix=""</parameter>: This forces the programs
to be installed into the <filename class="directory">/bin</filename>
directory. Having the programs available there is useful in the event of
the <filename class="directory">/usr</filename> partition being
unavailable.</para>
