    At least in principle: script -a commands-output <<< "tree dir"
    But I actually don't know if script reads from stdin like this anyway.

    So:

    script -ac "tree dir" commands-output

    Note: I do endorse using script for this. A useful command that many don't know about.

    Nope. The OP "... would have liked to have the reference command,
    and then everything else." script -c does /not/ write the command
    into the typescript file.

    11:53 $ cat tree_ac.txt
    cat: tree_ac.txt: No such file or directory

    11:54 $ script -ac "tree tmp" tree_ac.txt
    Script started, file is tree_ac.txt
    tmp
    |-- a.out
    |-- tst
    `-- tst.c

    0 directories, 3 files
    Script done, file is tree_ac.txt

    11:54 $ cat tree_ac.txt
    Script started on Thu 30 Jun 2022 11:54:09 AM EDT
    tmp
    |-- a.out
    |-- tst
    `-- tst.c

    0 directories, 3 files

    11:54 $

    But
    echo "command" | script
    /does/ write the command into the typescript file

    11:56 $ cat tree_a.txt
    cat: tree_a.txt: No such file or directory

    11:56 $ echo "tree tmp" | script -a tree_a.txt
    Script started, file is tree_a.txt
    tree tmp
    11:56 $ tree tmp
    tmp
    |-- a.out
    |-- tst
    `-- tst.c

    0 directories, 3 files
    11:56 $ exit
    Script done, file is tree_a.txt

    11:56 $ cat tree_a.txt
    Script started on Thu 30 Jun 2022 11:56:30 AM EDT
    tree tmp
    11:56 $ tree tmp
    tmp
    |-- a.out
    |-- tst
    `-- tst.c

    0 directories, 3 files

    11:56 $

    Script done on Thu 30 Jun 2022 11:56:30 AM EDT
    11:56 $
