ARRAYS (DEFINE & ACCESS) IN SHELL SCRIPTING || LINUX || UNIX || ARRAY INITIALIZATION AND ACCESSING
Define Array
1) array_name[index]=value1
array_name[index]=value2
- - - - -
2) array_name=(value1 value2 value3 .........)
3) array_name=([index]=value1 [index]=value2 [index]=value3 . . . . .)
Access Elements of Arrays
1) ${array_name[index]} - accessing single element
2) ${array_name[@]} - access all the elements of array
${array_name[*]} - access all the elements of array
3) ${array_name[@]:start_index} - access all the elements of array starts from given index.
4) ${array_name[@]:start_index:No_of_elements} - access given number of elements from given start index.
