Usage
    ansi [OPTIONS] [TEXT TO OUTPUT]

Option processing stops at the first unknown option or at "--".  Options
are applied in order as specified on the command line.  Unless --no-restore
is used, the options are unapplied in reverse order, restoring your
terminal to normal.

Optional parameters are surrounded in brackets and use reasonable defaults.
For instance, using --down will move the cursor down one line and --down=10
moves the cursor down 10 lines.

Display Manipulation
    --insert-chars[=N], --insert-char[=N], --ich[=N]
                             Insert blanks at cursor, shifting the line right.
    --erase-display[=N], --ed[=N]
                             Erase in display. 0=below, 1=above, 2=all,
                             3=saved.
    --erase-line=[N], --el[=N]
                             Erase in line. 0=right, 1=left, 2=all.
    --insert-lines[=N], --insert-line[=N], --il[=N]
    --delete-lines[=N], --delete-line[=N], --dl[=N]
    --delete-chars[=N], --delete-char[=N], --dch[=N]
    --scroll-up[=N], --su[=N]
    --scroll-down[=N], --sd[=N]
    --erase-chars[=N], --erase-char[=N], --ech[=N]
    --repeat[=N], --rep[=N]  Repeat preceding character N times.

Cursor:
    --up[=N], --cuu[=N]
    --down[=N], --cud[=N]
    --forward[=N], --cuf[=N]
    --backward[=N], --cub[=N]
    --next-line[=N], --cnl[=N]
    --previous-line[=N], --prev-line[=N], --cpl[=N]
    --column[=N], --cha[=N]
    --position[=[ROW],[COL]], --cup[=[ROW],[=COL]]
    --tab-forward[=N]        Move forward N tab stops.
    --tab-backward[=N]       Move backward N tab stops.
    --column-relative[=N], --hpr[=N]
    --line[=N], --vpa[=N]
    --line-relative[=N], --vpr[=N]
    --save-cursor            Saves the cursor position.  Restores the cursor
                             after writing text to the terminal unless
                             --no-restore is also used.
    --restore-cursor         Just restores the cursor.
    --hide-cursor            Will automatically show cursor unless --no-restore
                             is also used.

Report:
    ** NOTE:  These require reading from stdin.  Results are sent to stdout.
    ** If no response from terminal in 1 second, these commands fail.
    --report-position        ROW,COL
    --report-window-state    "open" or "iconified"
    --report-window-position X,Y
    --report-window-pixels   HEIGHT,WIDTH
    --report-window-chars    ROWS,COLS
    --report-screen-chars    ROWS,COLS of the entire screen
    --report-icon
    --report-title

Miscellaneous:
    --color-table            Display a color table.
    --color-codes            Show the different color codes.
    --icon=NAME              Set the terminal's icon name.
    --title=TITLE            Set the terminal's window title.
    --no-restore             Do not issue reset codes when changing colors.
                             For example, if you change the color to green,
                             normally the color is restored to default
                             afterwards.  With this flag, the color will
                             stay green even when the command finishes.
    -n, --no-newline         Suppress newline at the end of the line.
    --bell                   Add the terminal's bell sequence to the output.
    --reset                  Reset colors, clear screen, show cursor, move
                             cursor to (1,1), and reset the font.
