Hi !
Skype crashes time to time due to the webcam.

Is there a way to check the ps -aux if it is running on my X :0, and restart it when it crashed.

Would have someone bash/CODE to propose ?

thnaks a lot, thats very newby question level

assuming that skype (which i've never used, so don't know the behaviour or the binary name...) doesn't fork or have a more complex run logic, just use the fact that it's running to hold a loop...

Code:

while [ 1 ] 
do
  skype
  sleep 3 # could go nuts maybe, worth hanging up for a few seconds
done

use that script as a launcher in X and it'll always respawn automatically.

the thing is that [ 1 ]
should maybe be replaced by

"$(ps -aux | grep skype )" == "skype"
no ?

Also have a look at pgrep.

no?

no.... if skype crashes then the loop just starts again. there's no need to check if skype itself is running at all, that's the point of the infinite loop, just keep reloading it each time.

you could use pidof or something, but i think you're in danger of overengineering an otherwise very simple scenario.

yes
Ah, yes, it is indeed a nice idea, you got. I'd have the following question: how can I close it, when I log in the machine with ssh ?

Code:

killall -e skype

will obviouly not work

maybe:

Code:

# echo "while [ 1 ]  ; do  skype ; sleep 10 ; done" > /usr/bin/skypenocrash
# chmod +x /usr/bin/skypenocrash

then

Code:

$ skypenocrash &
$ killall -e skypenocrash

may work, no ?

I don't know whether it is the best solution. What would you think ?

Thanks !

well if all you want is to literally kill it, close the controlling terminal of ctrl+c it. there is going to be a bash instances which it running skype obviously, so you could easily get the parent process and kill that instance.

well, that might not be possible since it starts with the fluxbox startup, and I would have only ssh access.

no ctrl c. only some kill way...

Good evening & Regards
