xtermcontrol enables dynamic control of XFree86 xterm properties. It makes it easy to change colors, titles, fonts, and the geometry of a running xterm, as well as to report the current settings of the properties. Window manipulations such as (de)iconify, raise and lower, maximize and restore, and reset are also supported. It also lets advanced users issue any xterm control sequence.
The xterm program is the standard terminal emulator for the X Window System. It provides DEC VT102/VT220 and Tektronix 4014 compatible terminals for programs that can't use the window system directly. If the underlying operating system supports terminal resizing capabilities (for example, the SIGWINCH signal in systems derived from 4.3bsd), xterm will use the facilities to notify programs running in the window whenever it is resized.
terminal_colors is a tool to display a terminal color chart for 8, 16, 88, and 256 color terminals. It provides all the functionality of the various similar scripts found around the Web with some additional bells and whistles. It automatically detects 8, 16, 88, and 256 color capabilities (via ncurses) and displays the appropriate color charts. It can display the colors as blocks or (2D) cubes, optionally with color values overlaid in int or hex values. It can show the full rgb text string as well. It can also show the display with a vertical (default) or horizontal orientation. It has the option of additional padding and supports -h --help as well. It also works as a utility for converting between 256 and 88 color values.
