Explanation / Answer

1)$pwd
/Home
$ls
HW3.pdf q1,sh
$cat q1.sh
if [ -e /HW3.pdf ]
then
echo the full path of HW3.pdf is 'pwd'
else
echo HW3 does not exist in current directory.
fi
$./q1.sh

Output: HW3 does not exist in current directory.

2) $cat q2.sh
#!/bin/sh
res=0
x=0
check command line
if [ $ -lt 2 ] ; then
echo "Oops! I need atleast 2 command line args"
echo "Syntax: $0: number1 number2 ... numberN"
echo "Example:$0 56 66 34"
exit 1
fi
for i in $0
do x= 'expr $x + $i '
done
res='expr $x / $4 '
echo "res = $res"
$.q2.sh 3

Output: res= expr $x / $4

4) a) printf("%6d,%4d", 25, 1234);

Output: 25,1234

b) printf("%.4f", 3.1415926);

   Output: 3.1416

c) printf("%8.5e", 20.253);

  Output: 2.02530e+01
