Bash scripting: Local script execute function on remote server and return variables

[jdh239]

First off, I don't have a preference as to using a function or just a command. Function would be cool though. I need to create some populated variables (lists) on remote servers in order to execute commands against them. I can execute the command remotely, but can't get my variables populated.




create_lists () {
for i in $( ls $HOME_DIR | grep ^d | awk '{print $NF}' ); do
if id $i > /dev/null 2>&1 ; then
LIST="$LIST $i"
else
COMPARELIST="$COMPARELIST $i"
fi
done
export LIST
export COMPARELIST

for i in $COMPARELIST; do
if ! echo $IGNORELIST | grep $i > /dev/null 2>&1 ;then
GONELIST="$GONELIST $i"
fi
done
export GONELIST
echo $GONELIST
}



I was trying the following command to execute it remotely, but I really need to populate the variables. I know I could do this all with files, I was just hoping to avoid jumping through all of the hoops. Unsure if this is even possible (due to security or some other reason):




sshpass -p ${ROOT_PW} typeset -f | ssh ${BACKUP_USER}@${SERVER} "$(cat);create_lists"

If it helps, this passes a list across (I'm using passwordless login but that shouldn't matter):

~$ a="www xxx yyy zzz"
~$ ssh pi@192.168.0.103 "a='$a' ; echo \$a"
www xxx yyy zzz
