get-index() { Item=$1 Array="$2[@]" ArgArray=( ${!Array} ) NewArray=( ${!Array%%${Item}*} ) Index=${#NewArray[@]} [[ ${#ArgArray[@]} == ${#NewArray[@]} ]] && echo -1 || echo $Index } 您可以随后调用:
格式一:ARRAY_NAME[{#ARRAY_NAME[@]}]=value //标红部分表示数组长度,即要追加元素的下标 格式二:ARRAY_NAME[{#ARRAY_NAME[*]}]=value //标红部分表示数组长度,即要追加元素的下标 ⑥、删除数组中的某元素 撤销变量:#unset VAR //VAR是变量名 撤销数组中的某元素:#unset ARRAY[INDEX] //注意:不要加...
one more element than the array contains, resulting in an empty output on the last iteration. To avoid this, ensure that your loop condition isindex -lt ${#numbers[@]}(less than the length of the array), notindex -le ${#numbers[@]}(less than or equal to the length of the array)...
Associative Array Indexed arraysare a type of array where elements (values) are stored and assigned with an integer number starting from0toN. The elements inside the array are referenced using the index number. You will get to know more about this in the upcoming article. The main focus of ...
