Don't even know the language the "s/" thingie is from
My only exposure to it is on these forums and I submit that with only that knowledge of usage, it was correct.

It appears in several, including Perl
Here is your bug. That substitution on that subject line would give How mperny do you need to consume a month?
After you see why, you'll see why my version fixed it.
Cheers,
Ben

Gotcha
Need the spaces or all the a's get replaced.
Makes sense

s/all the a's/the first a/
you can add a g at the end of the command to replace all the occurences:
s/oldtext/newtext/g will replace all occurences of 'oldtext' with 'newtext' in the set of text you feed it.

Started in sed
Unix ed, ex/vi, and then Perl stole it from there.

That's the shell's behaviour, not sed's
Try it:
echo How many do you need to consume a month? | sed 's/ a / per /'
