This matches the open group specifications. http://pubs.opengroup.org/onlinepubs/009695399/utilities/echo.html ... APPLICATION USAGE It is not possible to use echo portably across all POSIX systems unless both -n (as the first argument) and escape sequences are omitted. The printf utility can be used portably to emulate any of the traditional behaviors of the echo utility as follows (assuming that IFS has its standard value or is unset): The historic System V echo and the requirements on XSI implementations in this volume of IEEE Std 1003.1-2001 are equivalent to: printf "%b\n" "$*" The BSD echo is equivalent to: if [ "X$1" = "X-n" ] then shift printf "%s" "$*" else printf "%s\n" "$*" fi New applications are encouraged to use printf instead of echo. - Graham _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
