[PATCH 0/3] trace-cmd: Updated bash tab completion

[Steven Rostedt]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

Played a bit with tab completion to fix some of the annoyances I've had,
and wanted with tab completion.

Steven Rostedt (VMware) (3):
  trace-cmd record: Add bash tab completion for -A
  trace-cmd record: Update -e event bash tab completion
  trace-cmd completion: Add instance completion for -B

[PATCH 1/3] trace-cmd record: Add bash tab completion for -A

[Steven Rostedt]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

Add a virsh lookup of guest names when -A is the option for trace-cmd
record and tab is done.

[PATCH 2/3] trace-cmd record: Update -e event bash tab completion

[Steven Rostedt]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

Update the tab completion to find events instead of needing to know the
systems.

[PATCH 3/3] trace-cmd completion: Add instance completion for -B

[Steven Rostedt]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

All commands but trace-cmd list use -B for instances. Since the list
command already has its own logic, make the default logic for all other
commands search the instances when -B is the previous command to complete.
