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 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'.

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
