That strace(1) command will have created one or more `st.*' files allowing you to see all the system calls the process and its children did, including what led to it deciding not to do any output. -- Cheers, Ralph.

Re: [arch-general] Impossible redirect console buffer to log
The output of the script command can contain all sorts of control characters and ANSI escape sequences since it is exactly what is being written to the terminal. Incidentally, I have written a Python function for cleaning up such output (solely used to document my Arch linux installation): https://bitbucket.org/cbillington/arch_install/src/default/arch_install.py#lines-58 It doesn't just remove the control characters (and ANSI escape sequences), it processes backspace characters and carriage returns etc to result in what you would have seen on your screen. It is not comprehensive but does a pretty good job. So you might want to postprocess your logs with that or similar. -Chris On Fri, Mar 1, 2019 at 3:41 PM Maykel Franco wrote: > El vie., 1 mar. 2019 a las 21:32, Chris Billington > () escribió: > > > > The 'flush' option could help with that: > > [bilbo:~]$ script -h | grep flush > > -f, --flush run flush after each write > > > > So, something like > > > > script -f -c '/usr/local/bin/cccam -d' mylogfile.log > > > > I would want to get to the bottom of why this binary does not play well > with normal tools, but if you just need things working, it looks like you > might have something workable with 'script'. > > > > -Chris > > > > On Fri, Mar 1, 2019 at 3:27 PM Maykel Franco > wrote: > >> > >> El vie., 1 mar. 2019 a las 20:08, Chris Billington > >> () escribió: > >> > > >> > This is pretty strange. > >> > > >> > As for the script command, it can be passed the command to run, but I > am guessing it will have the same symptoms as with 'unbuffer': > >> > > >> > [bilbo:~]$ script -c 'echo hello' mylogfile.log > >> > Script started, file is mylogfile.log > >> > hello > >> > Script done, file is mylogfile.log > >> > [bilbo:~]$ cat mylogfile.log > >> > Script started on 2019-03-01 14:05:28-05:00 [TERM="xterm-256color" > TTY="/dev/pts/0" COLUMNS="137" LINES="24"] > >> > hello > >> > > >> > Script done on 2019-03-01 14:05:28-05:00 [COMMAND_EXIT_CODE="0"] > >> > > >> > On Fri, Mar 1, 2019 at 1:40 PM Maykel Franco via arch-general < > arch-general@archlinux.org> wrote: > >> >> > >> >> El vie., 1 mar. 2019 a las 19:30, Ralph Corderoy > >> >> () escribió: > >> >> > > >> >> > Hi Maykel, > >> >> > > >> >> > > > command &> out > >> >> > > > >> >> > > Not works...

The 'flush' option could help with that: [bilbo:~]$ script -h | grep flush -f, --flush run flush after each write So, something like script -f -c '/usr/local/bin/cccam -d' mylogfile.log I would want to get to the bottom of why this binary does not play well with normal tools, but if you just need things working, it looks like you might have something workable with 'script'. -Chris On Fri, Mar 1, 2019 at 3:27 PM Maykel Franco wrote: > El vie., 1 mar. 2019 a las 20:08, Chris Billington > () escribió: > > > > This is pretty strange. > > > > As for the script command, it can be passed the command to run, but I am > guessing it will have the same symptoms as with 'unbuffer': > > > > [bilbo:~]$ script -c 'echo hello' mylogfile.log > > Script started, file is mylogfile.log > > hello > > Script done, file is mylogfile.log > > [bilbo:~]$ cat mylogfile.log > > Script started on 2019-03-01 14:05:28-05:00 [TERM="xterm-256color" > TTY="/dev/pts/0" COLUMNS="137" LINES="24"] > > hello > > > > Script done on 2019-03-01 14:05:28-05:00 [COMMAND_EXIT_CODE="0"] > > > > On Fri, Mar 1, 2019 at 1:40 PM Maykel Franco via arch-general < > arch-general@archlinux.org> wrote: > >> > >> El vie., 1 mar. 2019 a las 19:30, Ralph Corderoy > >> () escribió: > >> > > >> > Hi Maykel, > >> > > >> > > > command &> out > >> > > > >> > > Not works...

Re: [arch-general] Impossible redirect console buffer to log
This is pretty strange. As for the script command, it can be passed the command to run, but I am guessing it will have the same symptoms as with 'unbuffer': [bilbo:~]$ script -c 'echo hello' mylogfile.log Script started, file is mylogfile.log hello Script done, file is mylogfile.log [bilbo:~]$ cat mylogfile.log Script started on 2019-03-01 14:05:28-05:00 [TERM="xterm-256color" TTY="/dev/pts/0" COLUMNS="137" LINES="24"] hello Script done on 2019-03-01 14:05:28-05:00 [COMMAND_EXIT_CODE="0"] On Fri, Mar 1, 2019 at 1:40 PM Maykel Franco via arch-general < arch-general@archlinux.org> wrote: > El vie., 1 mar. 2019 a las 19:30, Ralph Corderoy > () escribió: > > > > Hi Maykel, > > > > > > command &> out > > > > > > Not works...

Otherwise, `LC_ALL=C strace -ff -o st /usr/local/bin/CCcam -d' will capture the write(2)s or similar and you can see what file descriptors its writing to and work backwards to see how that was obtained, e.g. by opening /dev/tty. -- Cheers, Ralph.

Re: [arch-general] Impossible redirect console buffer to log
The program could also explicitly be modifying its behaviour based on whether stdout is a tty or not. You can trick it into thinking its stdout is a tty with the program 'unbuffer'. For example: [bilbo:~]$ python -c 'import sys; print(sys.stdout.isatty())' | cat False [bilbo:~]$ unbuffer python -c 'import sys; print(sys.stdout.isatty())' | cat True So you might try: unbuffer /usr/local/bin/CCcam -d > file On Fri, Mar 1, 2019 at 1:04 PM Maykel Franco wrote: > El vie., 1 mar. 2019 a las 19:01, Chris Billington > () escribió: > > > > Perhaps the program writes its log to stderr, and not to stdout? > > > > If so, you can redirect both stdout and stderr to file with: > > > > command &> out > > > > > > > > On Fri, Mar 1, 2019 at 12:47 PM Maykel Franco via arch-general < > arch-general@archlinux.org> wrote: > >> > >> HI, I playing with cccam for a proyect with decoder and I like stdout > >> console log to specific log but not work... > >> > >> I try all: > >> > >> >> /var/log/test.log > >> > >> tee -a /var/log/test.log > >> > >> strace -p pid > >> > >> The command is: > >> > >> /usr/local/bin/CCcam -d > >> 18:43:15.717 CCcam: > >> == > >> 18:43:15.717 CCcam: starting CCcam > >> == > >> 18:43:15.717 CCcam: online using nodeId 91dd747775a31f66 > >> 18:43:15.735 CCcam: create 1 cam device(s) > >> 18:43:15.739 CCcam: readKeyfile: cannot open /var/keys/SoftCam.Key or > not found > >> 18:43:15.739 CCcam: readKeyfile: cannot open /var/keys/AutoRoll.Key or > not found > >> 18:43:15.739 CCcam: static cw not found or bad > >> 18:43:15.746 CCcam: parsed 11522 entries from /var/etc/CCcam.prio > >> 18:43:15.747 CCcam: added 1005 provider names from > /var/etc/CCcam.providers > >> 18:43:15.798 CCcam: added 11097 channel names from > /var/etc/CCcam.channelinfo > >> 18:43:15.798 CCcam: server started on port 47015 > >> > >> > >> > >> The binary program is: > >> > >> /usr/local/bin/CCcam: ELF 64-bit LSB executable, x86-64, version 1 > >> (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, > >> for GNU/Linux 2.6.32, BuildID[sha1]=6ab44025c0a35a3 > >> 83d63f30e96e489f29df424b5, stripped > >> > >> > >> I've tried everything, I do not know what to do to have that output > >> write it to log. > >> > >> I've tried inclusy with tty, pts but it's impossible. > >> > >> Does somebody knows why it could be? with any other command / program > works well > >> > >> with the only thing that I have managed to write to log is add: > >> > >> | stdbuf -oL > >> > >> but the program closes > > Thanks for your reply. > > Not works...
