Bash Shell determines if there is a given element in the array

#判断数组中是否有给定元素 #参数: 1 arrays; 2 element #返回: Yes/no # Example:
# Determine if there are elements in array Xrsh_array i3 # xrsh_array= (i1,i2,i3) # xrsh_tmp= ' echo ${xrsh_array[*]} ' # Xrsh_arrhasitem ' $XR Sh_tmp "" i3 "# returns YES # Note: The array needs to be converted when used as a parameter function xrsh_arrhasitem ()
{
   Local _xrsh_tmp
   Local _xrsh_array= ' echo ' $ ' '
   for _xrsh_tmp in ${_xrsh_array[*]}; do
     if test "$" = "$_xrsh_tmp"; then
       echo Yes
       return
     fi
   done
   echo no
}
