If your using bash, set extglob option:

Code:
#!/bin/bash
ftp_servers="b|c|d|e"
 
shopt -s extglob
case $1 in
    @($ftp_servers)) echo "server OK" ;;
    *) echo "Invalid server: $1" ;;
esac
shopt -u extglob

With ksh93 just put var straight in the case:

Code:
#!/bin/ksh93
ftp_servers="b|c|d|e"
 
case $1 in
    $ftp_servers) echo "server OK" ;;
    *) echo "Invalid server: $1" ;;
esac

otherwise, you can eval it, but it's pretty messy especially if you have any sort of complex code within the case,
I'd tend to call functions rather that putting too much code in there:

Code:
ftp_servers="b|c|d|e"
 
eval "case \$1 in
    $ftp_servers) echo \"server OK\" ;;
    *) echo \"Invalid server: \$1\" ;;
esac"

rabbitmq-env.conf

RABBITMQ-ENV.CONF(5)						  RabbitMQ Server					      RABBITMQ-ENV.CONF(5)

NAME

       rabbitmq-env.conf - default settings for RabbitMQ AMQP server

DESCRIPTION

       /etc/rabbitmq/rabbitmq-env.conf contains variable settings that override the defaults built in to the RabbitMQ startup scripts.

       The file is interpreted by the system shell, and so should consist of a sequence of shell environment variable definitions. Normal shell
       syntax is permitted (since the file is sourced using the shell "." operator), including line comments starting with "#".

       In order of preference, the startup scripts get their values from the environment, from /etc/rabbitmq/rabbitmq-env.conf and finally from
       the built-in default values. For example, for the RABBITMQ_NODENAME setting,

       RABBITMQ_NODENAME

       from the environment is checked first. If it is absent or equal to the empty string, then

       NODENAME

       from /etc/rabbitmq/rabbitmq-env.conf is checked. If it is also absent or set equal to the empty string then the default value from the
       startup script is used.

       The variable names in /etc/rabbitmq/rabbitmq-env.conf are always equal to the environment variable names, with the RABBITMQ_ prefix
       removed: RABBITMQ_NODE_PORT from the environment becomes NODE_PORT in the /etc/rabbitmq/rabbitmq-env.conf file, etc.

       # I am a complete /etc/rabbitmq/rabbitmq-env.conf file.
       # Comment lines start with a hash character.
       # This is a /bin/sh script file - use ordinary envt var syntax
       NODENAME=hare

SEE ALSO

       rabbitmq-server(1) rabbitmqctl(1)

EXAMPLES

       # I am a complete /etc/rabbitmq/rabbitmq-env.conf file.
       # Comment lines start with a hash character.
       # This is a /bin/sh script file - use ordinary envt var syntax
       NODENAME=hare

       This is an example of a complete /etc/rabbitmq/rabbitmq-env.conf file that overrides the default Erlang node name from "rabbit" to "hare".
