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'

NAME
anm - print name list SYNOPSIS
anm [-gnoprus] file ... OPTIONS
-g Global symbols only -n Sort numerically -o Prepend the filename to each line -p No sorting--use symbol table order -r Sort in reverse order -u List undefined symbols only -s Sort in section order EXAMPLES
anm -gn test.o # Print global symbols in numerical order DESCRIPTION
Anm prints the name list (symbol table) of each ACK format object file in the argument list. If no file name is given, a.out is used. Each symbol name is preceded by its value, a section indicator and a type indicator. The section indicators are: U Undefined symbol A Absolute symbol - Other symbol The type indicators are: F Filename M Module name S Section name E External (global) symbol - Local symbol The output is sorted alphabetically, unless otherwise specified. Notice that anm can only be used on ACK format object files (that is: .o and .out files). If you want to get the name list of an executable program use nm instead. SEE ALSO
