Bruce: According to "Mastering Regular Expressions," by Jeffrey E.F. Friedl, \xNN hex codes are not supported in sed. :-( For that you need awk, Perl, tcl, Emacs or Python. -----Original Message----- Just for my own edification, is there any way to grep for a certain non-printing ascii character? The Linux programming bible says \xyy would find ascii yy, for instance \x07 finds the ascii bell. But I wonder if maybe that only works in perl. bruce -- This is the [email protected] list.
