In array operator in bash

Question

Is there a way to test whether an array contains a specified element?

e.g., something like:

array=(one two three)

if [ \"one\" in ${array} ]; then
...
f         


        

Answer 1

if you just want to check whether an element is in array, another approach

case "${array[@]/one/}" in 
 "${array[@]}" ) echo "not in there";;
 *) echo "found ";;
