Copy content of parent directory to sub directory

Question

I need to copy the content of the parent directory to the newly created sub-directory.

Initially, the structure is like this:

Parent
    abc.txt
    work_dir/
        script.sh

Expected Output:

Parent
    abc.txt
    work_dir/
        script.sh
    sub_dir/
        abc.txt
        work_dir/
            script.sh

Now I am in the work_dir, and I am executing script.sh. The content of this file is below:

/bin/sh
mkdir ../sub_dir
shopt -s extglob
cp -r ../!(sub_dir) ../sub_dir/

I get the following error: syntax error near unexpected token `('. Error: exit status 2

If I change it to this cp -r '../!(sub_dir)' ../sub_dir/, I get cp: ../!(sub_dir): No such file or directory

Any help is appreciated, Thanks

`bash != sh` The `!( ... )` is an extglob feature from the `bash` shell. — Jetchisel, Nov 03 '21 at 12:14
when I change it to `bash` and then I run `mkdir ../sub_dir; shopt -s extglob; pwd; cp -r ../!(sub_dir) ../sub_dir/ ` I get `bash: !: event not found` — disp_name, Nov 03 '21 at 12:20
That is history expansion, It only happens from interactive shell. Disable it via `set +H` — Jetchisel, Nov 03 '21 at 12:22
The goal is to copy the parent folder content to the child folder. Is there any other way? — disp_name, Nov 03 '21 at 12:26
Just run `cp -r !("my sub dir") "my sub dir"` in the parent directory. Note that where the script lives has nothing to do with where it executes. — dan, Nov 03 '21 at 12:33
`cp -r ../!(sub_dir) ../sub_dir/` in a script works here with bash 5.0.3 and `extglob` enabled. — Renaud Pacalet, Nov 03 '21 at 12:38
Is the first line of your script really, literally `/bin/sh`? This would just start a new interactive subshell. — user1934428, Nov 03 '21 at 12:54
@Jetchisel : You are right, but in this case, the OP would see an error message saying that `shopt ` is not found. — user1934428, Nov 03 '21 at 12:56
You also did not say how you invoked your script. This makes it difficult to judge what's really going on. — user1934428, Nov 03 '21 at 12:56

rsync solved the issue. See the updated code:

/bin/sh
mkdir ../sub_dir
rsync -a --exclude=../sub_dir ../ ../sub_dir/
