Bug-Description:
|
|
|
462fb2 |
|
|
|
462fb2 |
Bash-4.2 does not attempt to save the shell history on receipt of a
|
|
|
462fb2 |
terminating signal that is handled synchronously. Unfortunately, the
|
|
|
462fb2 |
`close' button on most X11 terminal emulators sends SIGHUP, which
|
|
|
462fb2 |
kills the shell.
|
|
|
462fb2 |
|
|
|
462fb2 |
This is a very small patch to save the history in the case that an
|
|
|
462fb2 |
interactive shell receives a SIGHUP or SIGTERM while in readline and
|
|
|
462fb2 |
reading a command.
|
|
|
462fb2 |
|
|
|
462fb2 |
The next version of bash will do this differently.
