listOfNames="db_one db_two db_three"
for databaseName in $listOfNames
do
  echo $databaseName
done

或者只是

for databaseName in db_one db_two db_three
do
  echo $databaseName
done

这些答案中没有一个包含计数器。。。

#!/bin/bash
## declare an array variable
declare -a array=("one" "two" "three")

# get length of an array
arraylength=${#array[@]}

# use for loop to read all values and indexes
for (( i=0; i<${arraylength}; i++ ));
do
  echo "index: $i, value: ${array[$i]}"
done

输出：

index: 0, value: one
index: 1, value: two
index: 2, value: three

试试这个。它正在运行和测试。

for k in "${array[@]}"
do
    echo $k
done

# For accessing with the echo command: echo ${array[0]}, ${array[1]}

这与user2533809的答案类似，但每个文件都将作为单独的命令执行。

#!/bin/bash
names="RA
RB
R C
RD"

while read -r line; do
    echo line: "$line"
done <<< "$names"

如果您使用的是Korn shell，则有“set-A databaseName”，否则有“declare-A databaseName”

要在所有外壳上编写脚本，

 set -A databaseName=("db1" "db2" ....) ||
        declare -a databaseName=("db1" "db2" ....)
# now loop 
for dbname in "${arr[@]}"
do
   echo "$dbname"  # or whatever

done

它应该在所有外壳上工作。

声明数组不适用于Korn shell。对Korn shell使用以下示例：

promote_sla_chk_lst="cdi xlob"

set -A promote_arry $promote_sla_chk_lst

for i in ${promote_arry[*]};
    do
            echo $i
    done
