[dpdk-stable] [dpdk-dev] [PATCH] devtools: trap SIGINT is not recognizable to dash

[Gavin Hu]

Hi Stephen,

I am no sure only supporting bash is acceptable or not. Any impact to freebsd?

We should seek wider opinions about this.

I did not meet your problem, either bash or dash, what's your shell?

Best Regards,
Gavin
