====== bash variables ======

<2014.6.24>

===== List names, values and types of all variables =====

Useful on the command line, to see what you're working with:

<code bash>
declare -p
</code>

====== bash command prompt customization ======

<2016-01-27>

===== Show cwd basename, not entire absolute path =====

First, back up the copy of ''.bashrc'' that came with Ubuntu:

<code bash>
anthony@anthony-VirtualBox:~$ cp -p .bashrc .bashrc.orig
</code>

Changed ''\w'' (absolute path, I think) to ''\W'' ("basename", just the single directory name):

<code bash>
if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
# orig. line:
#    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
# adc changed 2016.01.27:
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\W\$ '
fi
</code>
