I'm using Ubuntu Hardy Heron, and can't work out how to run DRODTCBSetup-3.2.0.83.mojo.run - it would seem I need to extract it or something. Terminal just comes-up with

bash: DRODTCBSetup-3.2.0.83.mojo.run: command not found

Can someone tell me what I need to do? Thanks!

I am guessing that you run the file like

> DRODTCBSetup-3.2.0.83.mojo.run

This fails, because linux tries to append PATH variable in front of it (it contains /bin, /usr/bin and wherever system commands and programs are placed). Because none of those locations contain TCB installer, bash then tries to execute it as a command, and fails. If you want to run the installer, type

> ./DRODTCBSetup-3.2.0.83.mojo.run

This will direct the console to the current directory, where the file resides. If that still fails, you may have to run chmod to add execution permission (sudo chmod 755 DRODTCBSetup-3.2.0.83.mojo.run).

If you want, you can modify the PATH variable to contain current directory by default. You will have to append '.' (it is a dot) to the end. Just watch the separators, if you do.

EDIT: Correction. Bash first tries to execute the command as a built-in (echo, for example), and then scans for appropriate executable.

Thankyou!

Everytime you add '.' to the path god kills a wubba.

Please, think of the wubbas...

(Seriously: '.' has not been in the PATH for ages for security reasons. Best to keep it that way.)

Windows has '.' is the PATH for ages and this fact haven't created many problems (users know much more simplier ways to kill the system). These security reasons are obsolete if you use file manager like FAR/mc/totalcmd - you always see the full list of files in the current directory.

Well, there's also the fact that no one uses the command line on Windows, since, well, it sucks.

It's pretty easy to avoid the security issues if you just make sure to add '.' to the end of the path:

echo 'export PATH="$PATH:."' >> ~/.bashrc

For that to break, a hacker has to rely on you doing just the wrong misspelling at just the wrong filesystem location, and probably as just the wrong user.

I actually like keeping '.' out of my path because it makes it clear to me when I'm executing a local command (that's just me, maybe).

For anyone else having trouble getting DROD to work, remember to chmod +x the .run!

And to run it from GNOME, just right=click, properties, permissions, allow executing, then double-click. Presto, graphical installer.
