greenplum默认环境是bash，如何改成zsh环境

我发现一个好的解决办法，不知道有什么潜在的危险，首先gp给出了gp用到的命令有python写的，有perl写的，还有一部分是bash写的
如下:

List of Management Scripts Written in Bash
------------------------------------------
bin/gpcheckos.bash      -  Like gpcheckos, but in bash
bin/gpcrondump          -  Dumps a database
bin/gpdbrestore         -  Restores a database dumped from gpcrondump
bin/gpinitsystem        -  Creates a new Greenplum Database
bin/gpload              -  Sets env variables and calls gpload.py
bin/gpprintdbsizes      -  Removed in 4.0
bin/gprebuildsystem     -  Deprecated in 3.4

通过以上命令提供的线索找到bin目录下的lib目录下的gp_bash_functions.sh，注释一下代码即可

# Location Functions
#******************************************************************************
#Check that SHELL is /bin/bash
#       if [ $SHELL != /bin/bash ] && [ `ls -al /bin/sh|grep -c bash` -ne 1 ];then
#               echo "[FATAL]:-Scripts must be run by a user account that has SHELL=/bin/bash"
#               if [ -f /bin/bash ];then
#                       echo "[INFO]:-/bin/bash exists, please update user account shell"
#               else
#                       echo "[WARN]:-/bin/bash does not exist, does bash need to be installed?"
#               fi
#               exit 2
#       fi

gp有大量的管理脚本是bash的，你最好还是用bash来管理GP，或者修改一下已有的管理脚本，改成zsh兼容的。
