This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --WdKWsxsqsVCARrjrJ62n0GQWOPiuDPn1U Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Hello. I cannot use dtrace in FreeBSD for my need due to next bug. It's said that there's a build-in variable "cwd" contains "the name of the current working directory of the process associated with the current thread" [1] [1] http://docs.oracle.com/cd/E18752_01/html/819-5488/gcfpz.html But when I try to use the variable I get a failure: > dtrace: invalid probe specifier syscall:::entry { printf("%s", cwd); }: in action list: failed to resolve cwd: Unknown variable name You can get the same error by running a dtrace-script from official FreeBSD distribution: > /usr/share/dtrace/toolkit/opensnoop -c --=20 Best regards, Dmitry, head of UNIX-tech department NRNU MEPhI, tel. 8 (495) 788-56-99, add. 8255 --WdKWsxsqsVCARrjrJ62n0GQWOPiuDPn1U Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Using GnuPG with Icedove - http://www.enigmail.net/ iQIcBAEBAgAGBQJTiKIvAAoJEK2K5AyOMGec5NIQALeBg/HROWFknIyjbippK3HP Ll+iJJuK6G6YzSHLvo2brZO+rIH02nawVCRfZ4fn/iM1QYt/HZLGf9o/tdRCCGwP FXPd7Z8fm+cPZD1VbBw9YTN9z+9p0wkDJyaBEEqlmwSTKof/MCHw0oyk4mrqhemh 21BTLIzL49GvkZ5fSi/SjHK/puUAVFFoo7fmtVoYfxp0i3KPxNazNkcYQ4xCJuQx pF23aWsh6s7WemTwc3OWDE4jhXKjA5WJhYtY4Amx4yUHhMvMUrVgDONSxuDJe7BF HcBxcUd+OhR2LxQ2IgXLw+sPRk0bNMwKj+8XQ0B/CuKRWPjVhZiz7ctTTYyGVsNL N0c9ZZ1vXX+s1/VO/C1nm8fBX0NqiN/HuaQTuoJsiOj3gAm0RHDC90imjABwby33 ROisa+8FI947GeoDf7aSXjwiWPPKx22FvHz/VqnmOasdGAsJkpQLqILJ58WGjovu B65lTVwRYmJlh8MvVBcZxqMeGW2w/RmP+ttGhe7rZ7dLc7KjcxmJr9sUJ143JOJK tJyP1fwDfynPBTfpDe6VvVrhNbhEHi8EvveWB8yLTA4e2inZ2vpf8H3UYhoV9zLo /kOWim/8YyjToh9fNPoIvEs6wT+ISWnXFzLmDzdNJRLuouVr2kwFBLtFLZzm8GWZ rgYkOuR1AhhDAoMILw85 =N8Nf -----END PGP SIGNATURE----- --WdKWsxsqsVCARrjrJ62n0GQWOPiuDPn1U--
