在这个非常简化的示例中,我需要处理数组元素的键和值:
declare -A writer
writer[H.P.]=Lovecraft
writer[Stephen]=King
writer[Clive]=Barker
writer[Jack]=Ketchum
for i in ${!writer[@]}
do
echo "$i ${writer[$i]}"
done
fullname()
{
pointer=$1[@]
for i in "${!pointer}"
do
echo "? $i"
done
}
fullname writer
该函数必须以与示例循环相同的格式显示输出,并且它应该接收数组名称,键列表或值,而我尝试了所有这些操作,但均未成功。任何建议,不胜感激。
最佳答案
indir_keys() {
eval "echo \${!$1[@]}"
}
indir_val() {
eval "echo \${$1[$2]}"
}
fullname()
{
pointer=$1
for i in $(indir_keys $pointer)
do
echo "$i $(indir_val $pointer $i)"
done
}
给出:
Jack Ketchum
Clive Barker
Stephen King
H.P. Lovecraft
