diskusg(ADM)                    19 June 1992                    diskusg(ADM)


 Name

    diskusg - generate disk accounting data by user ID

 Syntax

    /usr/lib/acct/diskusg [ options ] [ files ]

 Description

    diskusg generates intermediate disk accounting information from data in
    files, or the standard input if omitted.  diskusg outputs lines on the
    standard output, one per user, in the following format: uid login #blocks

    where

    uid         the numerical user ID of the user.

    login       the login name of the user; and

    #blocks     the total number of disk blocks allocated to this user.

    diskusg normally reads only the inodes of file systems for disk
    accounting.  In this case, files are the special filenames of these de-
    vices.

    diskusg recognizes the following options:

    -s          the input data is already in diskusg output format.  diskusg
                combines all lines for a single user into a single line.

    -v          verbose.  Print a list on standard error of all files that
                are charged to no one.

    -ifnmlist   ignore the data on those file systems whose file system name
                is in fnmlist.  fnmlist is a list of file system names
                separated by commas or enclosed within quotes.  diskusg com-
                pares each name in this list with the file system name stored
                in the volume ID (see labelit(ADM)).

    -p file     use file as the name of the password file to generate login
                names.  /etc/passwd is used by default.

    -u file     write records to file of files that are charged to no one.
                Records consist of the special filename, the inode number,
                and the user ID.

    The output of diskusg is normally the input to acctdisk (see acct(ADM))
    which generates total accounting records that can be merged with other
    accounting records.  diskusg is normally run in dodisk (see acctsh(ADM)).

 Examples

    The following will generate daily disk accounting information:

    for i in /dev/dsk/0s1 /dev/dsk/0s3; do
            diskusg $i > dtmp.`basename $i` &
    done
    wait
    diskusg -s dtmp.* | sort +0n +1 | acctdisk > disktacct


 File

    /etc/passwd         used for user ID to login name conversions
