从rhel6.2服务器上的ksh脚本停止neo4j 2.0.0 M06时出错

Question

我的脚本包含以下代码：

bin_dir="/export/neo4j-community-2.0.0-M06/bin"
...snip...
  `$bin_dir/neo4j stop`
  stoprc=$?
  if [ "${stoprc}" -ne "0" ] ; then
    echo "Error stopping neo4j.  Please check that it is running."
    exit ${stoprc}
  fi

结果是

Stopping: not found [No such file or directory]
Return code is 127

以下是此脚本的ksh -x的输出。

+ /export/neo4j-community-2.0.0-M06/bin/neo4j stop
+ Stopping Neo4j Server '[13634]....' done
restore_graph.ksh[42]: Stopping: not found [No such file or directory]
+ stoprc=127

但是当我从命令行运行=“/ export / neo4j-community-2.0.0-M06 / bin / neo4j stop”时我没有问题：

: /export/neo4j-community-2.0.0-M06/bin/neo4j stop
Stopping Neo4j Server [12975].... done
: echo $?
0

Answer 1

这一行是问题

`$bin_dir/neo4j stop`

neo4j停止，但由于反引号，你执行neo4j stop的输出作为命令。

删除那些反引号。
