MRM(1)

NAME

mrm - Remove partitioned dataset members.

SYNOPSIS

mrm [-dfhv] <DATASET_PATTERN>[(<MEMBER_PATTERN>)]

-d
    Print out debug messages.

-f
    Force member deletion, use with caution!
    Note: wildcards will delete every matching member, whether or not
    it is being used.

-h
    Display syntax help.

-v
    Print out verbose command information.

DESCRIPTION

The mrm utility removes partitioned dataset members that match MEMBER_PATTERN. If no member pattern is specified, or if a member pattern of * is specified, all members of the dataset will be removed.

The partitioned dataset can be specified with wildcards, but only one partitioned dataset can match the pattern, otherwise an error is issued.

mrm is able to delete the members of a partitioned generation datasets (GDS). GDS relative name notation is supported when not using wildcard characters.

NOTE: Care should be taken with wildcards to avoid unintentionally deleting dataset members.

Using the -f option will use DISP=SHR on the whole PDS directory, so extra caution is advised when using wildcards. Changes made after the member has been deleted may create it once again.

EXAMPLES

Remove all members in dataset IBMUSER.PROJ23.LOAD:

mrm ibmuser.proj23.load

Remove members matching "MEM?" from two datasets:

mrm 'zoauser.pds1(mem?)' 'zoauser.pds2(mem?)'

Remove all members of IBMUSER.LOAD that start with TST and end with the character '1' followed by one additional character:

mrm 'ibmuser.load(tst*1?)'

Remove all members of IBMUSER.PROJ23.LOAD, assuming no other datasets also match the pattern IBMUSER.*23.LOAD:

mrm 'ibmuser.*23.load(*)'

Forcibly remove members that are in use:

mrm -f 'ibmuser.proj23.load(*)'

Remove all the members of the latest generation in the generation data group ZOAUSER.GDG:

mrm 'ZOAUSER.GDG(0)'

EXIT VALUES
