== 6. Managing your own program hierarchy (the LFS way) ==LFS stands for "Linux From Scratch". If you want your own set of programs, a few commands in your .profile will help:
# set LD_LIBRARY_PATH if not set
(echo $PATH | grep -q $HOME/usr/bin) || export PATH="$HOME/bin:$HOME/usr/bin:$HOME/usr/local/bin:$PATH"
fi
 
# export MANPATH="$MANPATH:/usr/local/teTeX/man"
# set MANPATH so it includes user's private bin if it exists
(echo $MANPATH | grep -q $HOME/usr/share/man) || export MANPATH="$HOME/usr/local/share/man:$HOME/usr/share/man:`manpath -q`"
fi
 
if [ -d "$HOME/usr/share/info" ]; then
export INFOPATH="$INFOPATH:$HOME/usr/share/info"
fi
 
if [ -d "$HOME/usr/lib/python" ]; then
(echo $PYTHONPATH | grep -q $HOME/usr/lib/python) || export PYTHONPATH="$HOME/usr/local/lib/python:$HOME/usr/lib/python"
fi
 
if [ -d "$HOME/usr/lib/pkgconfig" ]; then
(echo $PKG_CONFIG_PATH | grep -q $HOME/usr/lib/pkgconfig) || export PKG_CONFIG_PATH="$HOME/usr/lib/pkgconfig"
fi
This way, most ordinary commands like "man octave", "info octave", or launching octave itself, will first explore your own hierachy.
