grep -v 13 zeros in a string

but wait, what;s with the --hr 100? Are you trying to eliminate all but the first header? if so there's a switch for that too! --hr -1 suppresses all headers (btw - being lazy also invented hr to avoid typing headerrepeat 
), --hr 0 prints a single header and anything >0 repeats the header. generally when I find the need to do something different, I just invent a new switch. wait til you see the next version
It might be more interesting to tell me what you're trying to do and there might even be some more switches to help you out. for example if you're trying to generate output to load into mysql, maybe -P format would be more suitable.
also, how long do you want this command to run for and are the sampling intervals what you want? since this is actually interactive mode, you're sampling disk data every second and process data every 60. you can certainly change those but I often find it more useful to just run as a daemon and letting it run all the time. then, if you just want process/disk data, play back what was recorded and just display the subset you want. you may think you only want process/disk data now, but what if there's a problem and you wish you also had network, memory, etc at least recorded if not loaded into mysql?

diskd
diskd(1) General Commands Manual diskd(1) Name diskd - disk daemon; wait for disk to be inserted Note This manpage has been automatically generated from fdutils's texinfo documentation. However, this process is only approximative, and some items, such as cross-references, footnotes and indices are lost in this translation process. Indeed, these items have no appropriate rep- resentation in the manpage format. Moreover, only the items specific to each command have been translated, and the general information about fdutils has been dropped in the manpage version. Thus I strongly advise you to use the original texinfo doc. * To generate a printable copy from the texinfo doc, run the following commands: ./configure; make dvi; dvips fdutils.dvi * To generate a HTML copy, run: ./configure; make html A pre-made HTML can be found at: `http://www.tux.org/pub/knaff/fdutils' * To generate an info copy (browsable using emacs' info mode), run: ./configure; make info The texinfo doc looks most pretty when printed or as HTML. Indeed, in the info version certain examples are difficult to read due to the quoting conventions used in info. Description The diskd command has the following syntax: diskd [-d drive] [-i interval] [-e command] Diskd waits for a disk to be inserted into a given drive, and then either executes the command or exits. This program can be used to auto- matically mount a disk as soon as it is inserted. Warning This program works by switching the motor on for a very short interval, and then seeking to track -1. This might damage hardware in the long run. Amigas, which also use these techniques, are known for having problems with their disk drives no longer spinning up properly after a few month of usage. Options -d drive Selects the drive to observe for disk insertion. By default, drive 0 (/dev/fd0) is observed. -i interval Selects the polling interval. The interval is given in tenths of seconds. Default is 10 (one second). -e command Gives the command to be executed when a disk is inserted. If no command is given the program simply exits. Typically, the command mounts the disk. It can be a shell scripts which probes for several filesystems and disk geometries until it succeeds. Bugs * Automatic unmounting cannot yet be handled. It is indeed not enough to scan for disk removal, because when the disk is removed, it is already too late: There might be some buffers needing flushing. However, the fdmountd program allows automatic unmounting by using the SYNC mount options, which switches off write buffering (see section fdmount). * The drive motor is running all the time, and on some computers, the drive led flickers at each time the drive is polled.
