<para>Bash has a number of bugs in it that cause it to not behave the
|
|
way it is expected at times. Fix this behavior with the following
|
|
patch:</para>
|
|
|
|
<screen><userinput>patch -Np1 -i ../bash-&bash-version;-gnu-fixes-2.patch</userinput></screen>
|

<para>Now prepare Bash for compilation:</para>
|

|
|
<screen><userinput>./configure --prefix=/usr --bindir=/bin \
|
|
--without-bash-malloc --with-installed-readline</userinput></screen>
|
|
|
|
<para>Compile the package:</para>
|
|
|
|
<screen><userinput>make</userinput></screen>
|
|
|
|
<para>To test the results, issue:
|
|
<userinput>make tests</userinput>.</para>
|
|
|
|
<para>Install the package:</para>
|
|
|
|
<screen><userinput>make install</userinput></screen>
|
|
|
|
<para>Now run the newly compiled <command>bash</command> program (replacing the one you are currently executing):</para>
|
|
|
|
<screen><userinput>exec /bin/bash --login +h</userinput></screen>
|
|
|
|
<para>Note that the parameters used make it an interactive login instance
|
|
(so /etc/profile is read, if it exists, and the first found
|
|
~/.bash_profile, ~/.bash_login or and ~/.profile) and continue to
|
|
disable hashing so that new programs are found as they become
|
|
available.</para>
