I need to create an If Else awk script to count the following: How many times does Information Technology occur? How many Freshmen there are? How many Sophmore there are? How many Juniors there are? How many Seniors there are? How many Post-Bacc Undergrads there are? and output this info to the screen.

So far I only have this and needs some help tooling my script to work for all the questions one after the other in an If elseif else structure. Please help I know it needs alot of work, but I have been tinkering with it for 2 days now. the letters were my count variables.

Explanation / Answer

There are easier approaches to do this without if else

The simplest script is

tr -s ' ' ' ' < classroster | grep Information | wc -l
tr -s ' ' ' ' < classroster | grep Freshman | wc -l
tr -s ' ' ' ' < classroster | grep Junior | wc -l
tr -s ' ' ' ' < classroster | grep Sophmore | wc -l
tr -s ' ' ' ' < classroster | grep Senior | wc -l
tr -s ' ' ' ' < classroster | grep Post | wc -l

If we need to use if else then

information=0;

freshman=0;

junior=0;

sophmore=0;

senior=0;

post=0;

for i in `cat $filename`;

do if [ $i == "information" ];

then ((information++))

elif [ $i == "freshman" ];

then ((freshman++))

elif [ $i == "junior" ];

then ((junior++))

elif [ $i == "sophmore" ];

then ((sophmore++))

elif [ $i == "senior" ];

then ((senior++))

elif [ $i == "post" ];

then ((post++))fi $i;

done;

echo $information;

echo $freshman;

echo $junior;

echo $sophmore;

echo $senior;

echo $post;
