NAME

rwfileinfo - Print information about a SiLK file

SYNOPSIS

  rwfileinfo [--fields=FIELDS] [--summary] [--no-titles] FILE [ FILE ... ]

DESCRIPTION

rwfileinfo prints information about a SiLK file. The information that may be printed is:

format. The output file format, a string and its hexadecimal equivalent: FT_RWSPLIT(0x12), FT_RWFILTER(0x13), etc
version. The version of the above, an integer
byte-order. The byte-order (endian-ness) of the file, a string
compression. The compression library used to compress the data-section of the file, a string and its decimal equivalent (none(0), lzo1x(2). Does not include any external compression, such as if the entire file has been compressed with gzip(1).
header-length. The length of the header in bytes
record-length. The length of a single record in bytes
count-records. The number of records in the file
file-size. The size of the file
command-lines. The command(s) used to generate this file, for tools that support writing that information to the header and for formats that store that information.

OPTIONS

Option names may be abbreviated if the abbreviation is unique or is an exact match for an option. A parameter to an option may be specified as --arg=param or --arg param, though the first form is required for options that take optional parameters.

--fields=FIELDS

Determines which information about the file is printed. FIELDS is a list of integers representing fields to print. The FIELDS may be a comma separated list of integers; a range may be specified by separating the start and end of the range with a hyphen (-). The available fields are listed above. Fields are always printed in the order given above. If the --fields option is not given, all fields are printed.

--summary

Prints a summary that lists the number of files processed, the sizes of those files, and the number of records contained in those files.

--no-titles

Suppresses printing of the file name and field names; only the values are printed, left justified and one per line.

    byte-order      BigEndian
    compression     none(0)
    header-length   69
    record-length   32
    count-records   1109
