Attribute Lists

Many commands need to specify attributes to operate upon. For example, the modify command allows attributes to be changed and the create command often allows attributes to be created along with the object. In all cases, you can use an attribute list to specify the attributes and their values. This makes passing information from one command to another very easy. For example, an ACL copy operation can be written as follows:

# copy acl name1 to acl name2
# no error checking
proc acl_copy {name1 name2} {
acl replace $name2 -acl [acl show $name1]
}
