I created a little script that allow to make a rotation of values in an array. The goal was to shift the values to the right and that the last value of the array became the first value in order to create a rotation.
The purpose of the exercice was to do it without using a temporary array but to create a temporary variable in which I can put one of the values of the array then shifted all values to the right and then, put the temporary variable in the array.
Here my script :
Code:
#!/bin/bash
clear
declare -a array
read -rp " How many cases ? " box
read -rp " shift : " n
array=( $(seq 1 "$box"))
tmp=${array[-2]}
for((i=$tmp;i>0;i--))
do
array[$i]=${array[$i -1]}
done
array[0]=$tmp
for((i=0; i<$box;i++))
do
array[$i]
done
echo " Original array : " ${array[*]}
echo " Temporary variable : " $tmp
echo " Array shifted : ${array[*]}"

ARRAY_KEYS(3) 1 ARRAY_KEYS(3)array_keys - Return all the keys or a subset of the keys of an arraySYNOPSIS
array array_keys (array $array, [mixed $search_value], [bool $strict = false])
DESCRIPTION array_keys(3) returns the keys, numeric and string, from the $array.
If the optional $search_value is specified, then only the keys for that value are returned. Otherwise, all the keys from the $array are
returned.
PARAMETERS
o $array
- An array containing keys to return.
o $search_value
- If specified, then only keys containing these values are returned.
o $strict
- Determines if strict comparison (===) should be used during the search.
RETURN VALUES
Returns an array of all the keys in $array.
EXAMPLES
Example #1
array_keys(3) example
<?php
$array = array(0 => 100, "color" => "red");
print_r(array_keys($array));
$array = array("blue", "red", "green", "blue", "blue");
print_r(array_keys($array, "blue"));
$array = array("color" => array("blue", "red", "green"),
"size" => array("small", "medium", "large"));
print_r(array_keys($array));
?>
The above example will output:
Array
(
[0] => 0
[1] => color
)
Array
