-b Display the block number at the beginning of each line. 
-c Display the number of matched lines. 
-h Display the matched lines, but do not display the filenames. 
-i Ignore case sensitivity. 
-l Display the filenames, but do not display the matched lines. 
-n Display the matched lines and their line numbers. 
-s Silent mode. 
-v Display all lines that do NOT match. 
-w Match whole word

The following command would do it.

 sort FILE  | tr -d 'LIST OF SPECIAL CHARS' > NEW_FILE

grep searches inside all the files to find matching text. It doesn't really sort and it doesn't really chop and change output. What you want is probably to use the sort command

sort <filename>

and the output sent to either the awk command or the sed command, which are common tools for manipulating text.

sort <filename> | sed 's/REPLACE/NEW_TEXT/g'

something like above I'd imagine.
