问使用ls命令时，如何在文件夹名称中添加字符？

EN

#!/bin/bash

lsmod=($(ls)) # Convert ls output to an array
for folder in ${lsmod[@]}; do # Iterate over ls results
        if [[ -d $folder ]]; then # If this is a folder then...
                echo "=> $folder" # Put your char
        else # If not, display normally
                echo "$folder"
        fi
done

for i in `ls`; do echo $([[ -d "$i" ]] && echo "=> $i" || echo "$i"); done;
