Subject: [PATCH 26/42] perf tools: Check existence of _get_comp_words_by_ref when bash completing
Date: Thu,  4 Oct 2012 15:08:26 -0300	[thread overview]
Message-ID: <1349374122-27806-27-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1349374122-27806-1-git-send-email-acme@infradead.org>

From: Namhyung Kim <namhyung@kernel.org>

The '_get_comp_words_by_ref' function is available from the bash
completion v1.2 so that earlier version emits following warning:

  $ perf re<TAB>_get_comp_words_by_ref: command not found

Use older '_get_cword' method when the above function doesn't exist.
