    Hi Berni,

    1.- Debian and AlmaLinux are different operating systems, AlmaLinux is binary compatible with Red Hat. So, on Debian iotiop doesn't come installed by default.

    2.- The packages for binaries and man-pages are different on Debian and Debian based distros (in general). For example: you can install the wireshark-doc package -which is the documentation- without installing wireshark, which is the binary.

    For example: wireshark-doc is the documentation package for the wireshark tool.

    3.- For searching and installing the iotop tool you just can do the following:

    luis@debiansrv:~$ apt search iotop
    iotop/stable 0.6-42-ga14256a-0.3+b1 amd64
    simple top-like I/O monitor

    iotop-c/stable 1.30-1 amd64
    simple top-like I/O monitor (implemented in C)

    luis@debiansrv:~$ sudo apt install iotop
    Installing:
    iotop

    Summary:
    Upgrading: 0, Installing: 1, Removing: 0, Not Upgrading: 14
    Download size: 24.0 kB
    Space needed: 111 kB / 20.5 GB available

    Once installed you can run it using sudo.

    Regards,
    Luis.

    Hi Berni,

    If you do 'su' only, you won't have all the root's environment, including the PATH environment variable. So use 'su -' instead.

    Luis.
