In that bracketed expression, every single backslash intended as an escape sequence is absolutely unnecessary. Not only are the characters following the backslashes not special when in a bracketed expresion, neither is the backslash itself.

The repeated use of | is probably intended as an alternation operation, but since the pipe symbol is not special in this context, it is unintentionally added to the list of matched characters.

I recommend reading http://pubs.opengroup.org/onlinepubs...html#tag_09_03 to learn how bracketed expressions work within basic regular expressions.

The short version: There's almost nothing special within bracketed expressions, except for ], ^ (only if it occurs as the first character), and an embedded - (in the POSIX locale, used for range expressions).

Assuming I understood your intent (which is not a foregone conclusion), the following is a corrected version of what you suggested:
Code:
sed -e 's/[!@#\$%^&*()]//g'
