Run a program transparently, but print a stack trace if it fails

gdb -batch -ex "run" -ex "bt" ${my_program} 2>&1 | grep -v ^"No stack."$
For automated unit tests I wanted my program to run normally, but if it crashed, to add a stack trace to the output log. I came up with this command so I wouldn't have to mess around with core files. The one downside is that it does smoosh your program's stderr and stdout together.
Sample Output
Should be identical to what ${my_program} normally generates, unless ${my_program} crashes, in which case it ends with a stack trace.

Running this program smoothly as they are dealing with the best so far. I am grateful to this blog for sharing this program with us. I am looking forward to such kind of many programs to be offered by them in such a positive way and go to CocoFinder site to check imei tracking number and locate cell phone. So try to learn how to run them smoothly.
