comment How to display open file descriptors but not using lsof command
You probably want to know if your ulimit is exceeded, right? I blogged about this under linuxintro.org/wiki/Is_my_ulimit_exceeded; most importantly, the ulimit is a per-process restriction that you can find under /proc/PID/limits and instead of lsof I would use ls /proc/PID/fd to list the process' file descriptors.

you are right, I verified this with a test program, pasted to linuxintro.org/wiki/Ulimit

comment How to display open file descriptors but not using lsof command
@Gilles, do you have any reference for your statement? I looked into the man page and it explicitely states for -v that it is a per-process limitation but does NOT state this for -n.

/proc/sys/fs/file-nr gives me 3872 (and two other numbers). How can this be the count of files I have open if ulimit -n shows me 1024?

we need to understand exactly what you are doing. Call ekiga, click on the camera symbol, right?

Trying to add this issue to my tutorial on linuxintro.org/wiki/Set_up_a_web_cam. So your webcam works perfectly everywhere but in ekiga, right?

Thanks Gilles. And the second part of the second question - I can find this out with strace -s 9999.

comment how do applications communicate via sockets
when calling strace speaker-test I find a line connect(7, {sa_family=AF_LOCAL, sun_path="/run/user/0/pulse/native"}, 110) = 0 and then /proc/<pid-of-speaker-test>/fd/7 points to the receiving socket.

comment Where is “export var=value” not available?
Thanks Ulrich, Solaris may well be the culprit why this long syntax is still around.

comment Where is “export var=value” not available?
I can tell you I am using Linux since 2000 and I always tried to find out why people would do var=value;export var instead of export var=value and I never found a reason.

thanks I finally understood why I see so often the thing that I thought was useless: var=value;export var
