# OPTIONS

--all
  Select all the available programs. Be aware that the list of available programs is long. You will need a terminal window with more than 40 lines for the user interface to fit. Also make sure that the $LINES shell variable is exported, so txt2regex can detect the current number of available lines.

-h, --help
  Print the help message and quit.

--history <value>
  Print a regex from the given history data. The history value is shown in the last screen of the wizard, when you quit.

--make <label>
  Print a ready regex for the specified label. Inform an empty label to see the list of available labels.

--nocolor
  Do not use colors.

--prog <program1,program2,...>
  Specify which programs to use, separated by commas. Use --showmeta to see the complete list of available programs.

--showinfo <program>
  Print regex-related info about the specified program. Use --nocolor to have a text-only output (no control characters).

--showmeta
  Print a metacharacters table featuring all the programs.

-V, --version
  Print the program version and quit.

--whitebg
  Adjust colors for white background terminals.

# EXAMPLES
