PS1 is set and $- includes i if bash is interactive, allowing a shell script or a startup file to test this state. You can also test if you want with these two tests: if [[ "$-" =~ 'i' ]]; then echo interactive; fi if ( echo $- |grep i > /dev/null ); then echo interactive; fi Marian -- Best regards, Marian Marinov
