rwswapbytes(1) SiLK Tool Suite rwswapbytes(1) NAME rwswapbytes - Change the byte order of a SiLK Flow file SYNOPSIS rwswapbytes { --big-endian | --little-endian | --native-endian | --swap-endian } [--note-add=TEXT] [--note-file-add=FILE] [INPUT_FILE [OUTPUT_FILE]] rwswapbytes --help rwswapbytes --version DESCRIPTION Read the SiLK Flow records from INPUT_FILE, change the byte order of each record as specified by the --big-endian, --little-endian, --native-endian, or --swap-endian switch, and write the records to OUTPUT_FILE. rwswapbytes reads the input from the standard input either when no non-switch arguments are given or when INPUT_FILE is the string "stdin" or "-". rwswapbytes writes the output to the standard output either when the number of non-switch arguments is less than two or when OUTPUT_FILE is the string "stdout" or "-". rwswapbytes exits with an error code if an attempt is made to read or write binary data from or to a terminal. rwswapbytes is able to read and write files that have been compressed with gzip(1) when the file's name ends with ".gz". OPTIONS Option names may be abbreviated if the abbreviation is unique or is an ex- act 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. One of these switches must be provided: --big-endian Write the output file in big-endian (network byte-order) format. --little-endian Write the output file in little-endian (Intel) format. --native-endian Write the output file in this machine's native format. --swap-endian Unconditionally swap the byte-order of the input file. --help Print the available options and exit. --version Print the version number and information about how SiLK was configured, then exit the application. These switches are optional: --note-add=TEXT Add the specified TEXT to the header of the output file as an annota- tion. This switch may be repeated to add multiple annotations to a file. To view the annotations, use the rwfileinfo(1) tool. --note-file-add=FILENAME Open FILENAME and add the contents of that file to the header of the output file as an annotation. This switch may be repeated to add multiple annotations. Currently the application makes no effort to en- sure that FILENAME contains text; be careful that you do not attempt to add a SiLK data file as an annotation. ENVIRONMENT SILK_CLOBBER The SiLK tools normally refuse to overwrite existing files. Setting SILK_CLOBBER to a non-empty value removes this restriction. SILK_CONFIG_FILE This environment variable contains the location of the site configura- tion file, silk.conf(5). For additional locations where site configu- ration file may reside, see the "FILES" section. SILK_DATA_ROOTDIR This variable specifies the root of the directory tree where the data store of SiLK Flow files is maintained, overriding the location that is compiled into the tools (/data). rwswapbytes may search for the site configuration file, silk.conf, in this directory. See the "FILES" sec- tion for details. SILK_PATH This environment variable gives the root of the directory tree where the tools are installed. As part of its search for the site configura- tion file, rwswapbytes may use this variable. See the "FILES" section for details. FILES ${SILK_CONFIG_FILE} ${SILK_DATA_ROOTDIR}/silk.conf /data/silk.conf ${SILK_PATH}/share/silk/silk.conf ${SILK_PATH}/share/silk.conf /usr/local/share/silk/silk.conf /usr/local/share/silk.conf Possible locations for the SiLK site configuration file.
