[bbarrons]

I get an error when I try to install I tried sudo, as root, as zimbra user.... I know it must be something simple but I am lost.....
here is what I get
zimbra@ms2:/home/bbarrons/Documents$ sh ./zmbac.sh -install
[: 118: Illegal number:
touch: cannot touch `/var/log/zim_backup.log': Permission denied
./zmbac.sh: 124: Syntax error: "(" unexpected
this was as zimbra user as root I get
root@ms2:/home/bbarrons/Documents# ./zmbac.sh -INSTALL
bash: ./zmbac.sh: Permission denied
root@ms2:/home/bbarrons/Documents# sh ./zmbac.sh -INSTALL
[: 118: Illegal number:
./zmbac.sh: 124: Syntax error: "(" unexpected
What am I doing wrong?
thanks
Bill
