| Subject | [PATCH 10/10] perf test shell: Replace '|&' with '2>&1 |' to work with more shells |
| Date | 2017-08-16 22:30 +0200 |

From: Kim Phillips <kim.phillips@arm.com>
Since we do not specify bash (and/or zsh) as a requirement, use the
standard error redirection that is more widely supported.
