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?

convert - convert an audio file SYNOPSIS
[source_file] [target_file] [] [] [] [] [] [] [] DESCRIPTION
This command converts audio files from one supported file format, data format, sampling rate, and number of channels to another. The unconverted file is retained as a source file. are the file formats for the source and destination files. Each format can be one of these: Sun file format NeXT file format Microsoft RIFF Waveform file format MuLaw format ALaw linear 16-bit format offset (unsigned) linear 8-bit format linear 8-bit format If you omit uses the header or filename extension in the source file. You can omit if you supply a filename extension for the des- tination file. is the data type for the destination files. data_type can be one of these: MuLaw ALaw linear 16-bit offset (unsigned) linear 8-bit data linear 8-bit data If you omit uses an appropriate data type, normally the data type of the source file. are the number of samples per second for the source and destination file. Typical sampling rates range from 8 to 11k (for voice quality) to 44,100 (for CD quality). You can use to indi- cate thousands. For example, means 8,000 samples per second. If you omit uses a rate defined by the source file header or its filename extension. For a raw file with no extension, 8,000 is used. By playing the file, you can determine if 8,000 samples is too fast or too slow. If you omit uses a sampling rate appropriate for the destination file format; if possible, it matches the sampling rate of the source file. are the number of channels in the source and destination files. Use for mono; for stereo. If is omitted, uses the information in the header; for raw data files, it uses mono. If is omitted, matches what was used for the source file (through the header or option); for raw data files, it uses mono. EXAMPLES
Convert a raw data file to a headered file. Convert a raw data file to a headered file when the source has no extension, was sampled at 11,025 per second, and has stereo data. To save disk space, convert an audio file with CD quality sound to voice quality sound. AUTHOR
