-a             Adds the specified subsystem entry to the target
                   file.

    -d             Deletes the specified subsystem entry from the
                   target file.

    -f file        Specifies the input file, a stanza file that
                   contains entries for one or more subsystems. The
                   default target file is the SYSCONFIGTAB.DAT file.
                   Specify another target file by using the -t target
                   flag.

    -l             Lists the specified subsystem entries in the
                   target file. If you do not specify a subsystem
                   name, all subsystem entries in the target file are
                   listed. The SYSCONFIGTAB.DAT file is the default
                   target file.

    -m             Merges subsystem attributes specified in the input
                   file with the subsystem attributes in the target
                   file. If you do not specify a subsystem name, all
                   subsystem entries in the input file are merged.
                   The SYSCONFIGTAB.DAT file is the default target
                   file.

    -r             Removes the subsystem entries specified in the
                   input file from the target file. The only entries
                   removed are those that have attribute names and
                   values that exactly match those in the input
                   file. If you do not specify the subsystem name,
                   all subsystem entries in the input file with
                   attributes that match are removed from the target
                   file. The SYSCONFIGTAB.DAT file is the default
                   target database file.

    -t file        Specifies the target file for the operation. If
                   you do not specify this flag, the default target
                   file is the SYSCONFIGTAB.DAT file.

    -u             Replaces a subsystem entry in the target file with
                   the subsystem entry specified in the input file.
