배열선언

array_name_1=("value 1" "value 2" "value 3")

array_name_2=(1 2 3)

배열참조

array_name=("value 1" "value 2" "value 3")

 

echo "array_name[0]     = ${array_name[0]}"  #print array_name[0]

echo "array_name[2]     = ${array_name[2]}"  #print array_name[2]

echo "array_name[*]     = ${array_name[*]}"  #print array_name all item

echo "array_name[@]     = ${array_name[@]}"  #print array_name all item

echo "array_name index  = ${!array_name[@]}" #print array_name index number

echo "array_name size   = ${#array_name[@]}" #print array_name size

echo "array_name[0] size= ${#array_name[0]}" #print array_name[0] size

출력결과

array_name[0]     = value 1

array_name[2]     = value 3
array_name[*]     = value 1 value 2 value 3
array_name[@]     = value 1 value 2 value 3
array_name index  = 0 1 2
array_name size   = 3
array_name[0] size= 7
