Lists all attributes of the transaction logs. For each
    transaction log, both the full file specification of the
    transaction log and its size are displayed.

    If you do not specify which transaction log you want to display,
    the SHOW LOG command lists all transaction logs of the form
    SYSTEM$*.LM$JOURNAL, in all directories pointed to by the logical
    SYS$JOURNAL, which must be defined in executive mode in the
    system logical name table.
