netread(1) General Commands Manual netread(1) NAME
netread - read data transported over network using netwrite SYNOPSIS
netread [udp] [-f host ] [-c] [-C algorithm ] [-o file ] [-s] [-b] [-h <n> ] [-H] <n> ] [-q] [-v] [-vv] [-V] [-vV] netread is part of the netrw package. It is a simple (but powerful) tool for transporting data over the internet, in conjunction with netwrite(1) DESCRIPTION
The main purpose of netrw is to simplify and speed up file transfers to hosts without an FTP server. It can also be used for uploading data to some other user. It is something like one-way netcat (nc) with some nice features concerning data transfers. Netrw can compute and check message digest (MD5, SHA-1, and some others) of all the data being transferred, it can also print information on progress and average speed. At the end it sums up the transfer. OPTIONS
udp Changes the default TCP protocol can be changed to UDP. -f host Works in the firewall mode; connection is initiated by netread. -c This option is ignored. Transmission checksum is activated by default. -C algorithm Uses the specified algorithm for checksum. This option also implies -c . Supported algorithms (the first is default): sha1 md5 rmd160 none -o <file> Writes data to file instead of stdout. -s In case -o option is specified, open the file for synchronous I/O. Otherwise, this option has no effect. -b print speed in b/s instead of B/s -h <n> Prints `#' after each n KiB transferred (def. 10485.76). -H <n> Prints `#' after each n MiB transferred (def. 10.24). -q Be quiet. -v Be verbose. -vv Be very verbose. -V Show version. -vV Show verbose version. RETURN VALUES
0 no errors. 1 some error occured. 2 checksum validation failed. SEE ALSO

MD5SUM(1) User Commands MD5SUM(1) NAME
md5sum - compute and check MD5 message digest SYNOPSIS
md5sum [OPTION]... [FILE]... DESCRIPTION
Print or check MD5 (128-bit) checksums. With no FILE, or when FILE is -, read standard input. -b, --binary read in binary mode -c, --check read MD5 sums from the FILEs and check them --tag create a BSD-style checksum -t, --text read in text mode (default) The following five options are useful only when verifying checksums: --ignore-missing don't fail or report status for missing files --quiet don't print OK for each successfully verified file --status don't output anything, status code shows success --strict exit non-zero for improperly formatted checksum lines -w, --warn warn about improperly formatted checksum lines --help display this help and exit --version output version information and exit The sums are computed as described in RFC 1321. When checking, the input should be a former output of this program. The default mode is to print a line with checksum, a space, a character indicating input mode ('*' for binary, ' ' for text or where binary is insignificant), and name for each FILE. BUGS
Do not use the MD5 algorithm for security related purposes. Instead, use an SHA-2 algorithm, implemented in the programs sha224sum(1), sha256sum(1), sha384sum(1), sha512sum(1), or the BLAKE2 algorithm, implemented in b2sum(1) AUTHOR
