CWGEN(1)						      General Commands Manual							  CWGEN(1)

NAME

       cwgen - generate groups of random characters for Morse code practice

SYNOPSIS

       cwgen   [-g --groups=groups]   [-n --groupsize=groupsize]   [-n --groupsize=group_min-group_max]   [-r --repeat=repeat]	[-x --limit=limit]
       [-c --charset=charset]  [-h --help] [-V --version]

       cwgen installed on GNU/Linux systems understands both short form and long form command line options.  cwgen installed  on  other  operating
       systems may understand only the short form options.

       Options	may  be predefined in the environment variable CWGEN_OPTIONS.  If defined, these options are used first; command line options take
       precedence.

DESCRIPTION

       cwgen provides a simple method to generate groups of random characters for use as input into cw.  Command line options  control	the  group
       size, number of groups, and character set from which the random characters are selected.

   COMMAND LINE OPTIONS
       cwgen understands the following command line options.  The long form options may not be available in non-LINUX versions.

       -g, --groups
	      Specifies the number of groups of random characters to generate.	The default value is 128.

       -n, --groupsize
	      Specifies  either  the  number  of  random characters in each group, if a single value is given, or a range for the number of random
	      characters in each group if a dash-separated pair of values is given.  If a range is given, cwgen generates  groups  sized  randomly
	      between 'group_min' and 'group_max'.  The default value is 5.

       -r, --repeat
	      Specifies the number of times to repeat each group.  The default value is 0, indicating that each group is printed just once.

       -x, --limit
	      Specifies  an  upper  limit  on  the number of characters printed.  This option is useful when using random group sizes, to ensure a
	      given amount of practice text.  The default value is 0, indicating no upper limit on the number of characters printed.

       -c, --charset
	      Defines the  character  set  from  which	the  random  characters  are  selected.   The  default	value  is  'ABCDEFGHIJKLMNOPQRSTU-
	      VWXYZ0123456789'.

EXAMPLES

       Generate  20  groups  of 10 characters from the set EISH5, and sound them as Morse code.  Both short-form and long-form option examples are
       shown:

	      cwgen -g 20 -n 10 -c "EISH5" | cw -w 25 -t 850

	      cwgen --groups=20 --groupsize=10 --charset="EISH5" | cw --wpm=25 --tone=850
