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.

I don't know without seeing your sed statement, which I'm guessing is in shell not in Tcl (even though this is the Tcl forum?)

Wild guess - the space is delimiting shell parameters - place the whole of your sed edit instruction into quotes. So not

sed s/x/ /g abc.txt
sed 's/x/ /g' abc.txt
