Install bash 4.2.45 in 3 minutes or less

So here we go.

I set PS1 to '\t \$ ' in order to document the time required to do this. Everything was typed by hand and done from memory except a short alt-tab to nvALT to ensure proper numbering for curl'ing the patches.

• md src
• curl -OL http://ftpmirror.gnu.org/bash/bash-4.2.tar.gz
• tar xzf bash-4.2.tar.gz
• cd bash-4.2
• md patches
• curl -L "http://mirror.anl.gov/pub/gnu/bash/bash-4.2-patches/bash42-0[01-45]" -o "bash42-0#1"

• cd ..
• for patchfile in ./patches/*; do patch -p0 <"$patchfile"; done

• ./configure
• make -j4
• sudo make install

To wrap up simply edit /etc/shells like in my previous post and chsh -s on your user.
