One-dimensional arrays are supported by the Korn shell. On most systems, arrays can have a maximum of 512 elements. Array subscripts start at 0 and go up to 511. Any variable can become an array by simply referring to it with a subscript.

Array Variable Assignment Format

variable[0]=value variable[1]=value... variable[n]=value set A variable value0 value1... valuen typeset variable[0]=value variable[1]=value... variable[n]=value	assign values to array variable elements
set +A variable value0 value1... valuen	reassign values to array variable elements
typeset ?/span>attributes variable[0]=value variable[1]=value... variable[n]=value	assign attributes and values to array variable elements
typeset ?/span>attributes variable	assign attributes to array variable
typeset +attributes variable	remove attributes from array variable (except readonly)

Array Variable Evaluation

${array}, $array	array element zero
${array[n]}	array element n
${array[*]}, ${array[@]}	all elements of an array
${#array[*]}, ${#array[@]}	number of array elements
${#array[n]}	length of array element n
