在bash脚本中将变量传递给su命令

Question

I need to issue a command from a eg root to user zimbra. The problem is that I also need to set an env variable and some other variables.

From a command line I do it like this (that's command used for creating a mailbox in Zimbra):

su - zimbra -c 'export LC_ALL=nb_NO.UTF-8 && p="user.name" && domain="@example.com" && displayname="User Name" && givenname="User" && /opt/zimbra/bin/zmprov ca $p$domain "" cn "$displayname" displayName "$displayname" givenName "$givenname" zimbraPrefFromDisplay "$displayname"'

It works fine. The problem occurs when I try to automate the process in bash script. I can't (or don't know how to) pass a variable generated inside script to su command.

#!/bin/bash
var="something";
su - zimbra -c 'export LC_ALL=nb_NO.UTF-8 && echo $var'

When I use script above it doesn't work because $var is declared for root user, not for zimbra user. Is there a way to to baypass this?

I've tried to bypass this by generating a string first:

#!/bin/bash
var="something";
string="'export LC_ALL=nb_NO.UTF-8 && echo $var'";
su - zimbra -c $string

but when I do this I get

LC_ALL=nb_NO.UTF-8: -c: line 0: unexpected EOF while looking for matching `'' LC_ALL=nb_NO.UTF-8: -c: line 1: syntax error: unexpected end of file

Any help?

Unfortunately none of the above comments ideas worked for me. I wound up puzzling out that I could do the following. Escaping the double-quotes and wrapping in actual double-quotes seems absolutely necessary, plus pipe to xargs allowed the realized variable to be passed through.

echo "\\"/web/jboss-eap-7.1/bin/domain.sh -Djboss.domain.base.dir=$NODE/\\ &\\"" | xargs su - jboss -c

Hope this answer helps others!
