I have this in my .kshrc on my non-prod Oracle logins: export PS1='^[[0;32m^[[1m${HOST}:^[[1;33m${PWD}:^[[0;32m^[[1m${ORACLE_SID}^[[0m> ' And for the prod ones: export PS1='^[[0;31m^[[1m${HOST}:^[[1;33m${PWD}:^[[0;31m^[[1m${ORACLE_SID}^[[0m> ' The "32" changes the color to green, while "31" changes to red.
