[PATCH 21/31] perf tools: Fix the bash completion to support listing events for --event

From: Arnaldo Carvalho de Melo
Date: Thu Mar 19 2015 - 13:17:19 EST

From: Yunlong Song <yunlong.song@xxxxxxxxxx>

The bash completion only supports -e rather than --event, so fix it.


Before this patch:

$ perf record --event <TAB>

As shown above, the events of record does not come out.

After this patch:

$ perf record --event <TAB>
lignment-faults cpu/instructions/
L1-dcache-prefetch-misses node-prefetches
branch-instructions cpu/mem-loads/
L1-dcache-store-misses node-prefetch-misses
branch-load-misses cpu-migrations
L1-dcache-stores node-store-misses
branch-loads dTLB-load-misses
L1-icache-load-misses node-stores

As shown above, the events of record can come out now.
