When running checkpatch.sh, it generates the following error
on some linux distributions(like Debian) with Dash as the
default shell interpreter.
trap: SIGINT: bad trap

The fix is to replace SIGINT with INT signal, it works for
both bash and dash.

Fixes: 4bec48184e ("devtools: add checks for ABI symbol addition")
Cc: stable@dpdk.org

Checked with Ubuntu 16.04.4 LTS, it works.

This patch alone is not sufficient to make checkpatch run successfully

./devtools/checkpatches.sh: 52: read: Illegal option -d

It looks like the -d flag to read is also a bash extension.

I recommend changing both checkpatches.sh and check-symbol-changes to have #!/bin/bash

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

I am running Debian testing, still see complaints about -d

$ dpkg -S /bin/sh
diversion by dash from: /bin/sh
diversion by dash to: /bin/sh.distrib
dash: /bin/sh


Also, requiring bash is not that big an issue on FreeBSD. We already require gnu make
so requiring gnu shell is not something developers should really mind.
