set a fancy prompt

PS1=’${debian_chroot:+($debian_chroot)}\u@\h:\w\$ ‘

BLU=”[\033[0;34m]” #Blue. LGY=”[\033[0;37m]” #Light Gray. LGR=”[\033[1;32m]” #Light Green. LBU=”[\033[1;34m]” #Light Blue. LCY=”[\033[1;36m]” #Light Cyan. LRE=”[\033[1;31m]” #Light Red. YEL=”[\033[1;33m]” #Yellow. WHT=”[\033[1;37m]” #White. RED=”[\033[0;31m]” #Red. OFF=”[\033[0m]” #None. LASTSTAT=”\$(if [ \$? -eq 0 ] ; then echo -n ‘${LGR}:-)${LBU}’ ; else echo -n ‘${LRE}:-(${LBU}’ ; fi )”

PS1=”${LASTSTAT} ${BLU}[${LGR}\H${OFF}${BLU}][${LCY}\w${BLU}]${LBU}\$${OFF} “

PS1=”${LASTSTAT} ${debian_chroot:+($debian_chroot)}${YEL}\u${LBU}@\h:${LCY}\w${LBU}\$${OFF} “
