@@ -4,6 +4,21 @@ GNU coreutils NEWS -*- outline -*- ** New features + As a GNU extension, 'chmod', 'mkdir', and 'install' now accept operators + '-', '+', '=' followed by octal modes; for example, 'chmod +40 FOO' enables + and 'chmod -40 FOO' disables FOO's group-read permissions. Operator + numeric modes can be combined with symbolic modes by separating them with + commas; for example, =0,u+r clears all permissions except for enabling + user-read permissions. Unlike ordinary numeric modes, operator numeric + modes do not preserve directory setuid and setgid bits; for example, + 'chmod =0 FOO' clears all of FOO's permissions, including setuid and setgid. + + Also, ordinary numeric modes with five or more digits no longer preserve + setuid and setgid bits, so that 'chmod 00755 FOO' now clears FOO's setuid + and setgid bits. This allows scripts to be portable to other systems which + lack the GNU extension mentioned previously, and where ordinary numeric + modes do not preserve directory setuid and setgid bits. + dd now accepts the count_bytes, skip_bytes iflags and the seek_bytes oflag, to more easily allow processing portions of a file. |
