Your sed script probably doesn't do what you want it to. The \( and \) should be in the same command because they are used for grouping. If you are trying to replace literal parentheses with nothing, take away the backslashes (and probably the .* and especially the erroneous last * after the closing parenthesis). Or better still, use tr -d '()' < file or the near-equivalent sed 's/[()]//g'
