  "message": "Add new \"$_shell(CMD)\" internal function\n\nFor testing a following patch, I wanted a way to send a SIGINT to GDB\nfrom a breakpoint condition.  And I didn\u0027t want to do it from a Python\nbreakpoint or Python function, as I wanted to exercise non-Python code\npaths.  So I thought I\u0027d add a new $_shell internal function, that\nruns a command under the shell, and returns the exit code.  With this,\nI could write:\n\n  (gdb) b foo if $_shell(\"kill -SIGINT $gdb_pid\") !\u003d 0 || \u003cother condition\u003e\n\nI think this is generally useful, hence I\u0027m proposing it here.\n\nHere\u0027s the new function in action:\n\n (gdb) p $_shell(\"true\")\n $1 \u003d 0\n (gdb) p $_shell(\"false\")\n $2 \u003d 1\n (gdb) p $_shell(\"echo hello\")\n hello\n $3 \u003d 0\n (gdb) p $_shell(\"foobar\")\n bash: line 1: foobar: command not found\n $4 \u003d 127\n (gdb) help function _shell\n $_shell - execute a shell command and returns the result.\n Usage: $_shell (command)\n Returns the command\u0027s exit code: zero on success, non-zero otherwise.\n (gdb)\n\nNEWS and manual changes included.\n\nApproved-By: Andrew Burgess \u003caburgess@redhat.com\u003e\nApproved-By: Tom Tromey \u003ctom@tromey.com\u003e\nApproved-By: Eli Zaretskii \u003celiz@gnu.org\u003e\nChange-Id: I7e36d451ee6b428cbf41fded415ae2d6b4efaa4e\n",
