Bash programming does not have support for ternary operator syntax.
Ternary operators are written in the java language
The syntax is similar to if and else conditional expression. if expression is true, value1 is returned,else value2 is returned.
How to use ternary Operator in Bash
There are several ways we can write syntax in place of ternary operator syntax.
The first way, use if-else with expression syntax.
AGE=25 if [ "$AGE" -eq 25 ]; then result="true"; else result="false"; fi echo "$result" ;
The second way, use Arithmetic expressions using && and || Syntax is
[expression1] && Expression2|| Expression3
if the expression1 is true, Expression2 is evaluated, else Expression3 is evaluated
Here is an example program
[ $AGE == 25 ] && result="true" || result="false" echo "$result" ;
There is another way in which we can assign variables instead of expressions.
using let we can assign variables based on condition expression result
first=10 second=true third=false let result="(first==10)?second:third" echo $result # true
