Incorrect auto-indent bash

Question

Result of auto-indent in vim (filetype indent on)

main() {
    case $1 in  
        --ssh)
        echo "sshing into ${aws_ips[$1]}"
        ssh -i VPN_NODE_1.pem ${aws_ips[$1]}
    ;;  
    --scp)
        echo "scping $2 from ${aws_ips[$1]} to $3"
        scp -r -i VPN_NODE_1.pem ${aws_ips[$1]}:$2 $3  
        ;;  
    esac 

}

Expected:

main()
{
    case $1 in  
        --ssh)
            echo "sshing into ${aws_ips[$1]}"
            ssh -i VPN_NODE_1.pem ${aws_ips[$1]}
            ;;
        --scp)
            echo "scping $2 from ${aws_ips[$1]} to $3"
            scp -r -i VPN_NODE_1.pem ${aws_ips[$1]}:$2 $3
            ;;
    esac
} 

EDIT: My original post was incorrect. I was not using filetype indent on in my .vimrc, I was using it in the vim command prompt

Answer 1

I asked in comments for some of your settings and you replied with filetype=sh autoindent nocindent indentexpr=

If for indentexpr you instead had value GetShIndent() you'd have the indent scheme you want. You can manually set it up with :source $VIMRUNTIME/indent/sh.vim. But that's not what we want. With the proper configuration this should be picked up automatically when you open a shell file.

What's missing in your configuration? My best guess is that you need to add this to your vimrc:

filetype indent on

Check the current "indent" value (as well as a couple others, "plugin" and "detection" ) with plain :filetype. If you see indent:OFF then I'm on the right track and you should update your vimrc as suggested.
