Hi Damian,

It's the first expression which is the problem.
$ sed -e 's%[[./*$^\\]%\\&%g' </dev/null
sed: -e expression #1, char 18: unterminated `s' command
$ sed -e 's%.*%/^&:/d%' </dev/null
$
That's using the sed 4.7-1 package on Arch Linux.
It's because ‘[’ represents itself inside a character class unless it's
followed by a colon, dot, or equals because then it looks like the start
of a ‘[:digit:]’ or similar. Re-ordering works:
$ sed -e 's%[.[/*$^\\]%\&%g' </dev/null

Cheers, Ralph.
