man cwgen (Commandes) - generate groups of random characters for Morse code practice
NAME
cwgen - generate groups of random characters for Morse code practice
SYNOPSIS
cwgen [-g groups] [--groups=groups] [-n groupsize] [--groupsize=groupsize] [-c charset] [--charset=charset]
cwgen also accepts the -h, --help, -v and --version options.
The LINUX version understands both short form and long form command line options. Other versions 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. Only the short form options are 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 the number random characters in each group. The default value is 5.
- -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 --hz=850
