https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=199976 Bug ID: 199976 Summary: [patch] implement xargs -P0 Product: Base System Version: 11.0-CURRENT Hardware: Any OS: Any Status: New Keywords: patch Severity: Affects Some People Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: lifanov@mail.lifanov.com Keywords: patch Created attachment 156407 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=156407&action=edit xargs: implement -P0 This simple patch implements GNU-like xargs -P0 to run "as many processes as possible". This option is convenient and allows many of my scripts to port. There are a couple of differences from GNU behavior to make this consistent with other options in our xargs: -P takes negative numbers, which mean the same as -P0, and the maximum number of procs is equal to maxargs rather than some *_MAX macro. This is probably what the user wants, performs a lot better, and doesn't hurt intended -P0 portability. Tested with: kyua test -k /usr/tests/Kyuafile usr.bin/xargs (passed) -- You are receiving this mail because: You are the assignee for the bug.
