This program prints the current working dir to the standard output, shortening it nicely if it is too long. It can be used to build a nice bash prompt. E.g.
/home/johndoe/documents/some-project/src/
becomes
.../some-project/src/
These instructions apply to Debian based systems.
If you need g++ run sudo apt-get install g++. Compile the program
by executing
g++ small-prompt.cpp -o small-prompt
To use this as your bash prompt, put it somewhere in your PATH (for
instance, create ~/bin/ and put it there). Now run
echo 'PS1="$(small-prompt 30)\$ "' >> ~/.bashrc
If you want a color version, instead run
echo 'PS1="\[\033[0;31m\]\$(small-prompt 30)\$\[\033[0m\] "' >> ~/.bashrc
Restart your session for the change to take effect.
