An array is a list of variables. For example, we can create an array FRUIT
, which will contain many fruit names. The array does not have a limit on how many variables it may contain. It can contain any type of data. The first element in an array will have the index value as 0:
student@ubuntu:~$ FRUITS=(Mango Banana Apple) student@ubuntu:~$ echo ${FRUITS[*]} Mango Banana Apple student@ubuntu:~$ echo $FRUITS[*] Mango[*] student@ubuntu:~$ echo ${FRUITS[2]} Apple student@ubuntu:~$ FRUITS[3]=Orange student@ubuntu:~$ echo ${FRUITS[*]} Mango Banana Apple Orange
You will learn about creating an array in the Bash
shell.
If the array name is FRUIT
, then we can create an array as follows:
FRUIT[index]=value
Index
is the integer value. It should be 0 or any positive integer value.
We can also create an array as follows:
$ declare -a array_name $ declare -a arrayname=(value1 value2 value3)
Example:
$ declare -a fruit=('Mango' 'Banana' 'Apple' 'Orange...
