Add additional configuration to the user's Bash profile

additional_configuration.sh

#
# Append those lines to the user's `.bashrc`
#
# If the `.bash.d` folder exists, it would 'source' any `sh` script file.
# Keep your configuration organized :)
#

if [ -d ~/.bash.d ]; then {
    for i in ~/.bash.d/*.sh; do {
        if [ -r $i ]; then {
            source $i;
        } fi;
    } done;
    unset i;
} fi;

Thanks for sharing!

I'm not sure whether it was intentional or not, but you don't really need the curly braces or semicolon at the end of each statement, so this could be simplified to:

if [ -d ~/.bash.d ]; then
    for file in ~/.bash.d/*.sh; do
        if [ -r $file ]; then
            source $file
        fi
    done

    unset file
fi
