NAME

cmu_del_logical_group -- Delete a logical group.

SYNOPSIS

#/opt/cmu/bin/cmu_del_logical_group <-f filename -h>

#/opt/cmu/bin/cmu_del_logical_group <logical_group_name1, logical_group_name2, .....>

DESCRIPTION

Delete a logical group.

OPTIONS

-h--help

show help

-f--filename inputfile

delete logical group(s) listed in inputfile

EXAMPLES

To delete the logical groups rh5u5_x86_64 and sles11sp1_x86_64:

#/opt/cmu/bin/cmu_del_logical_group rh5u5_x86_64 sles11sp1_x86_64

To delete a list of logical groups from file logical_group_list:

#/opt/cmu/bin/cmu_del_logical_group -f logical_group_list

The file logical_group_list contains one logical group per line without spaces or blanks.
