I use a program that is saved in my /home/vincent/Downloads directory (program is actually a game, I downloaded it...AppImage file), I normally start the program by double-clicking on it... Now I would like this program to be available to all users.

Is it correct that I just need to move the AppImage file to e.g. /opt and give all users the permissions to execute the AppImage file ? Would chmod 1 be enough permissions?

I could also download the program into each user's home but that seems wrong...

  • You didn't provide OS/release details; but for my non-corporate desktops, I usually put my global executables in /usr/local/bin/ as that directory is empty on new installs (thus anything in it I put there), is already in the $PATH for systems I use (thus no changes required). Of course if using a corporate/enterprise system - I follow site policies on where files get placed.

Is it correct that I just need to move the AppImage file to e.g. /opt

Correct except /opt is not in the default path of all users, but /usr/local/games is and seems the right place for your purpose.

... and give all users the permissions to execute the AppImage file ? Would "chmod 1" be enough permissions ?

You mean chmod 111 file ... No, users will also need the reading permissions set as well i.e. chmod 555 file is the minimum for what you want unless all the users are in the same group as the owner of the file where in this case chmod 550 file will suffice.

Notice according to man chmod "Omitted digits are assumed to be leading zeros" ... Therefore, taking what you wrote literally, chmod 1 will actually translate to chmod 001 denying all permissions from owner user:group and leaving executable permissions for anyone else ... I already assumed you didn't mean to do that, but if you indeed meant to deny all permissions from the owner user and group, then the minimum for you is chmod 5 file or more explicitly chmod 005 file which will allow, ironically, only Others to execute the file.

    Generally for /opt/ you have an executable you need to link to file in PATH. Or start an systemd service.

  • @Rinzwind I've also seen /opt/bin added to paths before

  • @Rinzwind I'm not, but the people who did it certainly were.
