BASH PATCH REPORT
=================
Bash-Release: 4.2
Patch-ID: bash42-008
Bug-Reported-by: Doug McMahon <mc2man@optonline.net>
Bug-Reference-ID: <1299441211.2535.11.camel@doug-XPS-M1330>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2011-03/msg00050.html
Bug-Description:
Bash-4.2 does not attempt to save the shell history on receipt of a
terminating signal that is handled synchronously. Unfortunately, the
`close' button on most X11 terminal emulators sends SIGHUP, which
kills the shell.
This is a very small patch to save the history in the case that an
interactive shell receives a SIGHUP or SIGTERM while in readline and
reading a command.
The next version of bash will do this differently.
Patch (apply with `patch -p0'):
