NAME rand -- randomize the order of a stream SYNOPSIS rand [-lwvh] [-f <input file>] [-o <output file>] [--help] [--version] DESCRIPTION rand has 2 major modes of operation. The first is as a pipe. The sec- ond is to act on a specified file. There are 2 minor modes of opera- tion, the data can be randomized by line or word. As a pipe, rand collects the stream until it terminates, then displays the randomized results of this completed stream. If the stream is the result of several operations, then the stream as a whole is randomized. When operating on a file, rand will read the input from a single given file, and display the results to stdout. The two command line parameters control if the randomization is per line or word. The default behavior is to randomize by line. rand will randomize by word, and return one word on every line. A word in this sense is any string delimited by a whitespace. Tabs, spaces, and new- lines are ignored. OPTIONS [-l] Line shuffle [-w] Word shuffle [-c] Character shuffle [-v, --version] Show version and exit. [-h, --help] Show help and exit. [-f <file>] Read from <file> instead of stdin. [-<file>] Write to <file> instead of stdout. EXAMPLES play `find -name *.wav | rand ` rand -w -f COPYING -o whatever rand -l -f history.test -o test.1 /bin/ls | rand -w DIAGNOSTICS rand returns EXIT_SUCCESS on success or EXIT_FAILURE on failure. The only cases where EXIT_FAILURE may be returned are • -f file can not be read. • -o file cannot be written to. • An unknown option is presented (in which case, usage is also printed) SEE ALSO sort(1), rand(3) HISTORY rand was created in October of 1998 when Erik Greenwald got tired of hacking things to shuffle stuff. BUGS rand has no known bugs. Please report any to <erik@brlcad.org> AUTHOR Erik Greenwald <erik@brlcad.org> <erik@brlcad.org> December 11, 1998 RAND(1)
