Title: How to delay the launch of an application?
Post by: elrick on August 30, 2013, 11:00:58 AM

Hi guys,
I need your help. I'am trying to set up Putty, to load session on startup in Core Plus. I've wrote short script:

Code: [Select]

putty -load SessionNameI've saved file as putty.sh and I placed it in .X.d folder, its working, but it fails to load session, I think its because network is not ready, so how can I delay startup of putty?

I tried:

Code: [Select]

putty -load SessionName | wait:20s

Code: [Select]

putty -load SessionName -wait:20s

Code: [Select]

putty -load SessionName -wait 20

Code: [Select]

putty -load SessionName -sleep:20s
and few other configurations, nothing works, what am i doing wrong?

hi elrick,

perhaps you were looking for the sleep command?

#!/bin/sh

sleep 10
putty -load SessionName

Hi netnomad
If his problem is waiting for the network card to be ready, the solution posted by gerald_clark in the thread I linked to
is more robust.

Yes, a fix dealay is a bad practice, just a final solution. Much better to wait for the network is up with timeout.

ok its working but not always, I have two separate networks, maybe that's causing problems, when my PC is connected to the hub and to the one of networks, script is working, and when it's boot I can see IP address for a second, when my PC is connected to the other network, when it boot I see quick message "sending discover" or "waiting for IP 60", after this putty fails to load session, and its taking about 30-60 seconds network to start working.

Here my bootlocal.sh script:

Code: [Select]

#!/bin/sh
~ put other system startup commands here
/opt/eth0.sh &
SEC=60
while [ $SEC -gt 0 ] ; do
   ifconfig | grep -q "Bcast" && break || sleep 1
   echo -ne "Waiting for IP $((SEC--))  \r"     
done                                       
echo

and putty.sh in .X.d folder

Code: [Select]

#!/bin/sh
putty -load SessionName
