For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
mounting/unmounting scsi

Posted by tommaco (tommaco), 22 December 2006
I'm attempting to create a small GUI using SpecTcl which would simplify mounting and unmounting scsi drives.  Currently I am using the command

exec echo "scsi add-single-device 1 0 1 0" > /proc/scsi/scsi
exec echo "scsi remove-single-device 1 0 1 0" > /proc/scsi/scsi

The add part will work like this, but unmounting the drive brings up and error on how the drive does not exist.  The line still works, and will unmount but the error causes the rest of the function to quit out.

I've narrowed it down to exec which I seem forced to use while in tcl.  Any help on this would be greatly appreciated.

You can probably catch the error so that the function doesn't quit. There's an example of catch here
