  1. [UbuntuGnome] Re: Start up script to run an app is not working properly

    root/root are not permissions. That is just the owner and group. What are the permissions? ls -al shows it. Any script must have execute permissions to be run, depend on the language used, and the...

    [other] Re: Were is "cd //" documenmted ?

    For all programmers, if you always use '/' as your directory separator, it works on all the popular OSes, including MS-Windows. Has for decades.

    Every shell I've used - probably all the popular...
  3. Re: Where can I learn most used Ubuntu Commands?

    No offense taken. Everyone has a point of view to share. There's no way to know what will "click" for any OP. The different perspectives are good, I hope. Once an OP makes a clear choice on the...

    usr/bin/env
    is probably the wrong path.
    /usr/bin/env is what you need.

    Always use sudo visudo to modify the sudoers. It checks for problems in the changes.

  6. Re: Where can I learn most used Ubuntu Commands?

    I use the commands located in

    /bin
    /usr/bin
    /sbin
    /usr/sbin


    on my systems. Each of those has a manpage which provides the official documentation for the command. Manpages are...
  7. Re: What is the minimum hardware requirement for Ubuntu Setup?

    There is little difference between a "desktop" and a "server" internals on Linux, but there is 1 huge difference. "Server" doesn't have any GUI, so if you aren't already comfortable managing a...

    [ubuntu] Re: Difference in LAN paths

    NFS.
    Probably want to use autofs to mount only when requested. Then the storage can be treated like local storage.

    sshfs is another option, but much slower because ssh encryption.
  9. Re: What should be the platform from Web development newbie.

    What languages?
    What sort of programs?
    Are they micro-services, normal REST APIs, or full web-apps for end-users?

    I consider any IDE to be a mistake. A programmer who can be efficient with a...

  11. Re: DNS Records Configuration - Email Going Straight to Spam Box???

    The MX looks fine to me.
    The SPF looks fine to me.
    I don't use DKIM.

    TLS has always been automatic for postfix. A few years ago, I made it mandatory for all connections. My email server doesn't...

    Reverse DNS doesn't seem to be setup. Looks like DO owns that IP. While not strictly required, it is something that spam filters will consider. For a new domain, I suppose gmail is taking the...

    [lxqt] Re: Trouble with XRDP on Lubuntu 20.04 (LXQt)

    There are huge security implications between what xrdp does and what x2go does. On the same LAN, it probably doesn't matter. Over the internet, there is a world of difference. No way should anyone...

    Re: bash scripts and aliasing help please?

    For network backups, I use a root-equivalent account that allows just a few commands to be run, so any check of "root" will fail. Always check the uid ... the number -eq 0.

    Re: bash scripts and aliasing help please?

    Those two filenames are completely different.

  17. [kubuntu] Re: Is it possible to view shortcuts only in some activities?

    I doubt the manpage for ln will be too useful. ln -s is the way to create symlinks.

    .desktop files are completely different. I don't use those. Sorry.
  18. [kubuntu] Re: Is it possible to view shortcuts only in some activities?

    What is a shortcut? Do you mean a symbolic link or something else?
    Symlinks are file system objects. There's a wkipedia article if more info is needed.
