  1. #!/bin/sh
  2. # gen v1.6.7 - Generates random patterns of characters with the option to exclude certain regions of the ASCII table.
  3.  
  4. ERROR(){ # display error message, infotext and exit with return code 1
  5.     printf "\n\033[0;31mError - $1\033[0;32m\n\n"
  6.     cat <<EOF
  7.  Usage: gen.sh -c [number of characters] -luns -e [start-end] -i [character(s)] -m
  8.  
  9.     -c [n] .............. number of random characters to be generated
  10.     -l ................................... exclude lower case letters
  11.     -u ................................... exclude upper case letters
  12.     -n .............................................. exclude numbers
  13.     -s ........................................ exclude special signs
  14.     -e [start-end] .............. exclude a custom ASCII table region
  15.     -i [character(s)] .................. include certain character(s)
  16.     -f ......................... no linefeed at the end of the string
  17.     -d [string] .... put [string] between each character as delimiter
  18.     -m .......................... memorize (copy string to clipboard)
  19.  
  20.  If using the -e option, you may enter a single ASCII code or a whole range from start to end code with a minus "-"
  21.  in between. You can also enter several codes and ranges, all separated by comma (i.e. -e 33,58-64,... and so on).
  22.  The -i option will add characters on top of of the excluded ones meaning that they will be added even if they belong
  23.  to an excluded group. Using this option you may enter a single character or a whole group in a single row.
  24.  If you try to include special signs you may put them in quotes (single ' or double " while single quotes are more secure)
  25.  to prevent the shell from misinterpreting them as function (i.e. -i '&/\' ). Thus single and double quotes can't be
  26.  used as part of the random pattern at all. Remember that xclip must be installed in order to use the -m option.
