I tried it too, but things didn't work as described above, from line
one. After assigning to MY and doing a simple echo, bash printed:
aaabbb.c
The initial single backslashes are stripped to begin with (normal escape
processing). So I could not get any output looking like "/aaa/bbb.c".
Perhaps I missed something in an earlier post?
I got the last part, unterminated `s' command, in both bash
2.03.0(2)-release (CD 1.0) and 2.04.0(1)-release (from the net). As
Chris notes this is normal behavior due to two passes through the
interpreter for command substitution rather than one as in the first sed
case.
