Linux Bash Arithmetic Expressions Question:
What is the output of this program?
#!/bin/bash
a=10
b=$(( $a<0?10:$a<100 ))
echo $b
exit 0
a) 10
b) 20
c) 1
d) 0
Answer:
c) 1
Firstly the '$a<0' condition has been checked. Because it is false hence the right hand side condition of the colon (:) has been checked and this is true so program output is 1.
