In newer strace's, when both -c and -ff are invoked, strace returns the following error: "strace: -c and -ff are mutually exclusive options". This is also now documented in the strace(1) manpage with:
-ff If the -o filename option is in effect, each processes trace is written to filename.pid where pid is the numeric process id of each process. This is incompatible with -c, since no per-process counts are kept. Given that the current behavior notifies the user won't do what is requested, and it is documented in the strace manpage, closing as Fix Released.Thanks! ** Changed in: strace (Ubuntu) Status: Confirmed => Fix Released -- 'strace -ff -c -o filename' spits out null output https://bugs.launchpad.net/bugs/53974 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
