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

array="one two three"
if [ $(echo "$array" | grep one | wc -l) -gt 0 ] ; 
  then echo yes; 
fi

If that's ugly, you could hide it away in a function.
