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.
Selecting file names in a shell - one word or another

If you want to select all file names that include the words "cat" or "dog" in them with file name matching, you can do so using curly braces - that's supported by most modern shells as part of what is known as "globbing".

Here's an example - I've just been copying images off my digital camera and I wanted all files from 28th January, 31st January and 1st February - so file names starting P128, P131 and P201, and this is what I wrote:

cp /Volumes/Untitled/DCIM/100OLYMP/P{128,131,201}* .

Sometimes, there is confusion between square brackets and curly braces in file name matching. If I had written
[128,131,201]
I would have been looking for any ONE character from the list in the brackets - so that's a 0 1 2 3 8 or comma (and the specification of the comma 1 and 2 several times would have shown that I didn't realise what I was doing. And if I had written
[128][131][201]
then I would have been looking for a 1 2 or 8 followed by a 1 or 3 (or 1!) followed by s 2 a 0 or a 1

Oh - want to see one of the pictures?
