fiThe usage is mentuioned above of the script.
when i am running the script it is not throwing any error but not giving me the desired output for the one case that is--
mt_clean -a mtbackup
or
mt_clean -a mtBackup
first of all it is taking both without displaying any error and taking the doing some weird thing which i do not want.
first of all it should display a message that mtbackup is specified without -l/-L option.
can anybody help me out in this.
Thanks
