In Actor Prolog a resident is a special mechanism that helps processes to inspect state of other processes. A resident observes the state of a specified (target) process and if the state of the process changes (for instance, after message handling) it proves a specified predicate of the process. ...

. The shell uses a command called test to evaluate conditional expressions. Full details of this command can be found in the test manual page. For example: if test ! -f $FILE then if test "$WARN" = "yes" then echo "$FILE does not exist" fi fi . First, we test to see if the filename specified by the variable $FILE exists and is a regular file. If it does not then we test to see if the variable $WARN is assigned the value yes , and if it is a message that the filename does not exist is displayed.
