将当前文件名回显到文本文件 ubuntu 中？

Question

I normally just browse around and not looking to post questions however I am currently learning how to shell script and I've fallen into a pickle.

At the moment I have a structure of:

Main
---Hub1
---Hub2
---Hub3
---Hub4

All the way to Hub20.

What i want the structure to be is:

Main
---Hub1
--------Notes_1.txt >> "The <file_name> belongs to <user> and was created in Hub1"
---Hub2
--------Notes_2.txt >> "The <file_name> belongs to <user> and was created in Hub2"

and so on. At the moment my code is looking like this

i=1
until (($i>20))
filename="~/Main/Hub${i}/Notes_$i.txt"
do 
touch ~/Main/Hub${i}/Notes_$i.txt
echo "The $(basename -- "$filename") belongs to $USER was created in the Hub${i}" >> ~/Main/Hub${i}.txt
((i++))
done

Its not doing what it needs to be doing and I just cant figure out what I am doing wrong. I am aware it's not formatted right. It may be a simply solution or maybe I am completely off. I want to get it working before I start moving it around. Any advice would be great. Thank you!

You can use a brace range instead of until .

Don't put the pathname in quotes, that prevents expanding ~ .

You need $ before filename in the echo statement to expand the variable.

for i in {1..20}; do
    filename=~/Main/Hub${i}/Notes_$i.txt
    touch "$filename"
    echo "The $(basename -- "$filename") belongs to $USER was created in the Hub${i}" >> ~/Main/Hub${i}.txt
done
