执行bash脚本时出错

Question

我想使用此bash脚本将分支分支到位于子目录中的几个git项目中。

gzz (){

for d in admin_pci merchant_pci gateway_pci gw_plugin gateway_web_console web_payment
do
    ( cd $d && git pull && git checkout $(git branch -r | grep "$1" | awk '{print substr(""$1"",8,length)}'); )
done
}

使用gzz feature/b2017110901_develop_submdoule_update时，我得到：

gzz feature/b2017110901_develop_submdoule_update
Already up-to-date.
D   config/database.yml.example
Already on 'feature/b2017110901_develop_submdoule_update'
Your branch is up-to-date with 'origin/feature/b2017110901_develop_submdoule_update'.

...completed.

但是当我使用gzz开发时，我得到了

error: pathspec 'develop' did not match any file(s) known to git.

如果我手动执行脚本，它将正常运行。

您能给我一些可能出问题的建议吗？
