This week, we're updating our course layouts and descriptions. Presentation and materials always gently change over time, but just occasionally there's a need to make a step change to clear out some of the old and roll in the new. That's now happening - but over a long and complex site it's not instant and you'll see sections of the site changing up to and including 19th September.

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