如何在Ksh中迭代多个字符串

您可以对此使用间接寻址:

for i in {1..6}
do
  file="file$i"
  dest="dest$i"
  echo "${!file} ${!dest}" #or whatever you want to do with each file
done

从…起 How can I use variable variables (indirect variables, pointers, references) or associative arrays?

BASH允许您间接扩展一个参数,即 变量可以包含另一个变量的名称:

 # Bash
 realvariable=contents
 ref=realvariable
 echo "${!ref}"   # prints the contents of the real variable

file[1]="${HOME_PATH}/data1.dat"
file[2]="${HOME_PATH}/one/model1/data2.dat"
file[3]="${HOME_PATH}/two/model2/data3.dat"
file[4]="${HOME_PATH}/three/model3/data4.dat"
file[5]="${HOME_PATH}/three/model4/data5.dat"
file[6]="${HOME_PATH}/three/model5/data5.dat" 

dest[1]="${DEST_PATH}/data1.dat"
dest[2]="${DEST_PATH}/one/model1/data2.dat"
dest[3]="${DEST_PATH}/two/model2/data3.dat"
dest[4]="${DEST_PATH}/three/model3/data4.dat"
dest[5]="${DEST_PATH}/three/model4/data5.dat"
dest[6]="${DEST_PATH}/three/model5/data5.dat"

for i in "${file[@]}"
do
    cp ${file[i]} ${dest[i]}
done
