You mean, like, testing $SHELL for being "/bin/ksh"? :) if [ "$SHELL" = "/bin/ksh" ]; then ksh-specific code else plain ol' Bourne shell fi ..or maybe even.. if expr "$SHELL" : '.*ksh$'; then ksh-specific code else plain ol' Bourne shell fi ..which would match 'ksh', '-ksh', '/bin/ksh', '/usr/local/bin/ksh', and other variations.
