Subject: vstart.sh: quote cmd params when display executing cmd
X-Git-Tag: v13.0.1~1123^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=refs%2Fpull%2F17057%2Fhead;p=ceph.git

vstart.sh: quote cmd params when display executing cmd

vstart.sh will echo executed cmd to the stdout:

/root/jiaying/ceph/build/bin/radosgw -c /root/jiaying/ceph/build/ceph.conf --log-file=/root/jiaying/ceph/build/out/rgw.j.log --debug-ms=1 -n client.rgw --rgw_frontends=civetweb port=8000

As params contain whitespaces, pasting the above cmd into the shell didn't start rgw
on the port 8000. Now the vstart.sh output is like the following:

'/root/jiaying/ceph/build/bin/radosgw' '-c' '/root/jiaying/ceph/build/ceph.conf' '--log-file=/root/jiaying/ceph/build/out/rgw.j.log' '--debug-ms=1' '-n' 'client.rgw' '--rgw_frontends=civetweb port=8000'

We can paste above cmd to the shell to restart rgw, it's more convenient for debugging.
