Compilation and Installation

To compile GNU Bash, run the following command:

make

The tests are not designed to work correctly running uner the root user. The tests will be run later when it is rebuilt as an RPM.

Finally, to install GNU Bash into the build tree, run the following command:

make DESTDIR=$PWD/DESTDIR install
pushd DESTDIR
    ln -sv usr/bin/bash usr/bin/rbash
    ln -sv usr/bin/bash usr/bin/sh
    install -v -d -m755 -o root -g root etc
    install -v -d -m755 -o root -g root etc/skel
    install -v -d -m755 -o root -g root etc/skel/.bashrc.d
    install -v -d -m755 -o root -g root etc/profile.d
popd
cat <<EOF > DESTDIR/etc/skel/.bashrc

    . /etc/bashrc

export PATH

# Comment the following line if you like systemctl's auto-paging feature:
export SYSTEMD_PAGER=

# User specific aliases and functions
if [[ -d ~/.bashrc.d ]]; then
    for rc in ~/.bashrc.d/*; do
        if [[ -f "$rc" ]]; then
            . "$rc"
        fi
    done
fi
unset rc

# check for other alias or environment files
if [[ -f $HOME/.aliases ]]; then
    . $HOME/.bash.aliases
elif [[ -f $HOME/.bash.environ ]]; then
    . $HOME/.bash.environ
fi

if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi
