. 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.

Springtime in the Solar System . In our case, we can use the tilt theory of the seasons to make a prediction: that any tilted planet will have seasons, and that the strength of these seasons will depend on the amount of the tilt. ... At summer solstice, the north pole points straight at the Sun; the north polar regions have tropical weather, but the Southern Hemisphere is in total darkness. ... With a little trigonometry, you can calculate the angle of the Sun and the intensity of solar heating. ...
