[PATCH] devtools: check_symbol_change requires bash

[PATCH] devtools: check_symbol_change requires bash

[Stephen Hemminger]

The syntax of check_symbol_change uses some bash syntax.
It does not run correctly on Debian where /bin/sh is not the
same as /bin/bash.

I think this fix may be required for devtools/checkpatches.sh as well
since it seems to use bash specific call to trap().

I saw this in an internal bug report but didn't have a system to check
the fix on. Could you do a quick check.

Yes, checkpatches also needs to be bashifyed.

I would prefer we fix the root cause.
What is the error?

I see there are some == bashisms. Is there something else?

[PATCH] devtools: fix symbol check for dash

[Thomas Monjalon]

The script check-symbol-change.sh was not running when
/bin/sh redirects to dash.
